🇺🇸 U.S.A. FIRST

Ares Acres LLC is a U.S.-based authorized DJI Agras reseller supporting American agricultural drone operators with genuine DJI Agras OEM replacement parts, accessories, and field-ready inventory.

FREE & FAST Shipping is included for all U.S. customers.

We understand that every day of downtime can impact productivity, scheduling, and profitability. That's why we focus on providing fast fulfillment, responsive customer support, and reliable access to the parts operators need most.

When an isolation sleeve cracks or wears out, the pump loses its secure, cushioned seating. Vibration that used to be absorbed starts transferring straight into the airframe and plumbing — loosening fittings, stressing hoses, and accelerating wear across the whole spray system.

We use specialized technicians to verify and dispatch the Impeller Pump Isolation Sleeve ordered.

Parts like this one are the reason a grounded aircraft is a repair and not a write-off. A single component held in U.S. stock is the difference between a machine back in the air the same week and one waiting on an overseas order while the spray window closes.

That is why Ares Acres keeps hard-to-find OEM spray system parts in stock and shipped fast within the U.S.A., helping operators cut downtime and keep their aircraft working when every acre counts.

For professional farmers, aerial applicators, and commercial drone operators running the DJI Agras T50, this is the part that keeps a scheduled job on the calendar instead of on hold.

Ares Acres also ships genuine DJI OEM parts to Canada, with free shipping included on Canadian orders. Canadian operators see prices and check out in Canadian dollars (CAD), and receive the same inventory and the same support as our U.S. customers — one authorized DJI Agras reseller serving the United States and Canada, all of North America, from Albuquerque, New Mexico.

🔧 Component Overview

The DJI Agras T50 OEM Impeller Pump Isolation Sleeve is a molded OEM isolation housing designed for the impeller pump assembly of the DJI Agras T50 and DJI Agras T25 agricultural drones.

This sleeve seats around the impeller pump, providing the cushioned, isolated mounting the pump was engineered to operate in. It is the component that stands between a high-output spray pump and the rest of the aircraft — absorbing vibration, keeping the pump firmly positioned, and protecting both the pump body and the surrounding structure from wear.

Designed for the DJI Agras T50 and T25 platforms, this OEM sleeve is manufactured to match the impeller pump assembly for proper seating and secure hold. OEM construction helps maintain factory fitment and consistent isolation performance, so the pump runs the way it was designed to — tank after tank, season after season.

Commercial agricultural drones operate in demanding environments every day, including:

• Crop spraying
• Liquid fertilizer application
• Herbicide treatments
• Fungicide applications
• Insecticide spraying
• Orchard operations
• Vineyard spraying
• Specialty crop programs
• Precision agriculture missions
• Daily commercial deployments
• Fleet operations
• High-acreage contract work

Throughout these operations, pump mounting and isolation components are routinely exposed to:

• Continuous pump motor vibration
• Thousands of pump start-stop cycles
• Chemical contact and overspray
• Concentrated product exposure
• Fertilizer residue
• Pressure-washing and rinse cycles
• Heat generated by continuous pump operation
• UV exposure
• Rain and humidity
• Transport vibration
• Routine assembly and disassembly
• Long commercial operating hours

Over time, this combination of stress and exposure can crack, harden, or deform isolation sleeves — and a worn sleeve stops doing the one job it exists for: keeping pump vibration away from the rest of the aircraft.

The OEM Impeller Pump Isolation Sleeve helps maintain:

• Secure impeller pump seating
• Proper pump alignment
• Effective vibration isolation
• Reduced vibration transfer to the airframe
• Protected pump housing
• Reduced stress on hoses and fittings
• Quieter, smoother pump operation
• Consistent spray system output
• Consistent maintenance standards
• Increased fleet readiness
• Maximum aircraft uptime
• Reliable commercial operation

For operators whose aircraft generate revenue every day, replacing worn pump mounting components before they fail is one of the cheapest forms of downtime insurance available.

Prove the mount before you condemn the pump. With the system depressurized and the tank empty, take hold of the pump body and try to rock and twist it in its seat. A sleeve that is still doing its job pushes back with a springy, damped resistance and returns the pump to where it started. A sleeve that has hardened feels dead and solid, with the pump moving as one piece with the bracket. A sleeve that has torn or taken a set lets the pump shift and then stay shifted. Those three feels are the whole diagnosis, and none of them require a tool.

Use a thumbnail on the material itself, not your eyes. Press firmly into a section of the sleeve away from a fastener. Compliant material dents and springs back within a second or two. Material that has been cooked by heat cycling and concentrated chemical resists the nail, leaves a white stress mark, or shows fine crazing where it was pressed. That is a sleeve that will keep looking perfectly serviceable in a photograph while transmitting every bit of pump vibration straight into the airframe.

Feel where the vibration steps down. Set the aircraft on a stand, put clean water in the tank, and run the pump. Lay a fingertip on the pump body, then on the bracket or airframe immediately outboard of the mount. There should be a clear drop in what you feel across that boundary, because that drop is the entire function of the part. If the two locations feel the same, nothing is being isolated regardless of how the sleeve looks. Repeat the check on a sibling aircraft if you have one and the comparison becomes obvious.

Separate a mounting problem from a plumbing problem by changing the tank level. Cavitation, a sucking air leak on the intake side, or a partially blocked strainer all change character as the tank empties and as the pump primes, and they usually come with pressure that wanders. Vibration caused by a failed isolator does not care how much liquid is in the tank; it is there from the first second the pump runs and it stays the same until the pump stops.

Look for the dust the part leaves behind as it dies. A sleeve that is fretting against metal sheds fine dark rubber powder that collects in the corners of the cradle and around the fastener heads, and it polishes bright witness marks onto the surfaces it is rubbing. Both are proof of relative movement that should not exist. Paint pen witness marks across the pump hardware are worth adding at the same time, because hardware that repeatedly breaks its own witness line is telling you the vibration is not being absorbed anywhere.

Distinguish hardening from chemical swelling, because they look nothing alike on the bench and they mean different things about your operation. A hardened sleeve is stiff, sometimes glossy, and often slightly shrunken so the pump feels loose in it. A chemically attacked sleeve is the opposite: swollen, tacky or spongy to the touch, sometimes noticeably larger than the new part beside it, and it may refuse to go back over the pump body. Swelling points at concentrated product sitting in the pump bay rather than at hours in service.

⚙️ Functional Purpose

The OEM Impeller Pump Isolation Sleeve is designed to house, seat, and isolate the impeller pump assembly of the DJI Agras T50 and T25.

The component helps:

• Seat the impeller pump securely
• Maintain proper pump positioning
• Isolate pump vibration from the airframe
• Dampen pump operating noise
• Protect the pump body from contact wear
• Reduce stress on spray hoses and fittings
• Support consistent pump output
• Support stable spray system pressure
• Replace cracked or hardened sleeves
• Restore factory pump mounting
• Maintain OEM fitment
• Preserve factory isolation geometry
• Protect adjoining spray components from vibration wear
• Simplify pump service and reassembly
• Support preventative maintenance
• Reduce preventable repairs
• Reduce preventable downtime
• Improve long-term spray system reliability
• Increase fleet readiness
• Keep spare-parts inventory field-ready

Reliable spraying starts with a pump that runs smooth, seated exactly the way the factory intended.

A properly seated OEM isolation sleeve keeps the pump cushioned and aligned through thousands of acres of commercial work, protecting spray output, the pump itself, and every component around it.

A worn, cracked, or hardened isolation sleeve may contribute to:

• Excess pump vibration
• Vibration transfer into the airframe
• Loosening fittings and fasteners
• Stress cracking in hoses and connections
• Pump movement or misalignment
• Increased pump operating noise
• Accelerated pump housing wear
• Inconsistent spray pressure
• Interrupted spraying missions
• Unexpected downtime
• Higher repair costs over time
• Reduced fleet reliability

Replacing worn isolation components helps restore the smooth, secure pump operation the spray system was engineered around.

Do the dirty work before you open anything. Flush the spray system with clean water, run the pump long enough to clear concentrate out of the plumbing, then depressurize and drain. Everything you are about to touch has been wet with concentrated crop protection product, so gloves and eye protection are not optional here even though the part itself is only a piece of molded rubber. Have a rag and a catch tray ready, because there is always residual liquid trapped in the pump and the hose behind the fitting.

Photograph the assembly before a single fitting comes loose, and pay particular attention to the pump's clocking, meaning the angular position of its outlet and its cable exit relative to the bracket. That angle is what gives the hoses their natural, unstressed routing. A pump reinstalled a quarter turn from where it was will fit, run, and quietly load the hose and the fitting for the rest of the season. Note the routing and every clip the wiring passes through as well.

Break the electrical connection first, then the plumbing, then the mounting hardware, and support the pump as the last fastener comes out. Never let the pump hang on its hoses or its cable, even for a moment, because that is exactly how a barb cracks or a connector pin gets tugged. Once it is free, work the sleeve off by easing it around evenly rather than levering at one point with a screwdriver; a torn sealing lip on an old sleeve you were going to discard is fine, but the same technique on a new one is expensive.

Clean before you assemble. Wipe the pump body and the inside of the cradle until both are dry and free of grit, because a single piece of sand trapped between the pump and the sleeve becomes an abrasive point that will wear a hole through the wall from the inside where you cannot see it. If the new sleeve is a tight fit, use water or a weak soap solution as an assembly aid and let it dry. Do not use petroleum grease or spray lubricants on it. Those attack and swell many elastomers, and you would be starting the new part halfway to failure.

Seat the sleeve fully home so the pump body bottoms in it, then set the assembly into the cradle without twisting. An isolator that goes in wound up is preloaded before the pump has run a minute, and it fails early and unevenly on the side that was stretched. Check that any relief notch, cable slot, or deeper cup end lines up the way the removed part did, and confirm the orientation on the bench by laying old and new side by side rather than trying to work it out with the pump in your other hand.

The most important thing you can get wrong on refit is torque, because an isolator only works while it is free to flex. Crushing the sleeve down solid turns it into a rigid spacer and gives you an unisolated pump with a brand new part fitted. Bring the hardware down evenly, in stages, and only until the sleeve is properly captured. If the mount uses a metal shoulder or crush limiter, tighten to it. DJI does not publish a torque figure for this hardware in the general operator documentation, so if you do not have the service value, match the compression you saw on the removed sleeve and go no further.

⚠️ Common Replacement Indicators

Replacement may be recommended when operators observe:

• Cracked sleeve body
• Hairline stress fractures around mounting points
• Hardened or brittle sleeve material
• Deformed or warped sleeve
• Loose pump seating
• Pump shifting or rotating in its mount
• Increased pump vibration or noise
• New rattles from the pump area in flight
• Chemical-related deterioration or discoloration
• Visible wear at pump contact surfaces
• Missing or damaged sleeve sections
• Repeated re-tightening of pump hardware
• Maintenance inspection findings
• Pump replacement or rebuild projects
• Seasonal rebuilds
• Fleet refurbishment projects
• Preventative maintenance replacement
• Long-term commercial wear

Common causes of isolation sleeve failure include continuous vibration cycling from pump operation, chemical contact with concentrated crop protection products, heat cycling from long pump runs, UV degradation from all-day field exposure, over-tightening during pump service, and simple accumulated fatigue from thousands of operating hours.

Replacing isolation sleeves at the first sign of wear helps prevent the follow-on damage a loose, vibrating pump can cause. For commercial operators, preventative replacement is almost always less expensive than the downtime and secondary wear caused by an unisolated pump mid-season — and it is standard practice to replace the sleeve whenever the pump itself is serviced.

Spray pressure that flickers or hunts on the app while the aircraft is holding a steady flow rate and the strainer is clean: the pump is moving in its mount and the plumbing is flexing with it. The pump itself is still delivering, which is why operators chase the nozzles and the filter first and only get to the mounting after they have replaced things that were never wrong.

Pump hardware you find yourself re tightening every few weeks: the sleeve is no longer absorbing energy, so it is going into the fasteners instead. Retightening buys a short reprieve and does nothing about the cause, and every cycle of it works the bracket holes a little larger. Treat repeated loosening at one location as a diagnosis rather than a chore.

Fine dark rubber powder or bright polished witness marks around the pump mount: the sleeve is fretting against metal instead of flexing within itself. That is a part that has hardened, torn, or been crushed by overtightening, and the powder it is shedding is material it will not get back.

New buzzing or rattling from the pump bay that only appears in flight and cannot be reproduced on a stand: the pump vibration is now reaching the airframe and finding a resonance that only exists when the aircraft is loaded and airborne. A pump that sounds normal on the bench and awful in the air is almost always a mounting story rather than a pump story.

A sleeve that is swollen, tacky, or spongy, or that will not stretch back over the pump body: chemical attack from concentrated product sitting in the pump bay rather than fatigue. Fix the rinse routine at the same time as the part, because a new sleeve in the same environment goes the same way on the same schedule.

A sleeve that has visibly shrunk or gone glossy and hard, with the pump now a loose fit in it: heat cycling and age. This is the failure mode that hides best, because the sleeve is intact, correctly located, and completely useless, and nothing about a visual inspection will tell you so.

Cracks or tearing radiating from a fastener location rather than from the general body: overtightening, either on the last service or the one before. Look at the bracket hole underneath while you are there, because a fastener that has been working in an isolator that could no longer hold it has usually started to elongate its own hole.

📐 Specifications

DJI Material Number (SKU): YC.JG.ZS003417

Component Type: Impeller pump isolation sleeve / pump mounting housing

Compatibility:

• DJI Agras T50
• DJI Agras T25

Package Quantity: 1 Piece

Installation Area: Impeller pump assembly

Function: Houses, seats, and isolates the impeller pump; dampens pump vibration

Construction: Molded OEM component

Mounting Type: Direct-fit OEM replacement component

Application: Agricultural drone spray system maintenance

Mounting torque: Not published for this hardware in the general operator documentation. Use the DJI service figure if you have it. Without it, bring the hardware down evenly in stages and stop when the sleeve is captured, matching the compression witnessed on the removed part. Crushing an isolator solid removes its function entirely.

Failure mode to expect: Hardening rather than visible breakage. The part typically stiffens from heat cycling, chemical exposure, and age long before it cracks, and a stiff sleeve transmits vibration while looking new. Judge it by feel and by symptoms, not by appearance.

Orientation: Fitment is directional. Note which end of the removed sleeve carried the deeper cup, relief notch, or cable slot and match it on the bench before the pump goes near the aircraft. Also record the pump's clocking so hose routing returns unstressed.

Assembly aids: Water or a weak soap solution only, allowed to dry before running. Petroleum grease and spray lubricants attack and swell many elastomers and will shorten the life of a new sleeve from the day it is fitted.

Replacement grouping: Where an aircraft carries more than one pump, replace the sleeves as a set rather than one at a time, so both mounts have matched stiffness. Fit a new sleeve any time the pump itself is removed for service.

🧰 Fitment Verification Before You Order

This listing is DJI material number YC.JG.ZS003417. That number, not the description, is what makes a part match. Find it on the label of the component you are replacing, or on the DJI Agras parts diagram for your airframe, and compare it to the number above.

Revision suffixes are still the same part. DJI labels sometimes carry a trailing revision such as .01, .02, or .F. Those denote a production revision, not a different component. Match the base number and disregard the suffix.

Visually similar is not the same. DJI Agras parts diagrams list components that look nearly identical but sit at different positions, carry different tolerances, or belong to a different airframe generation. Ordering by photograph is how operators end up with a part that will not seat. Order by number.

Verified fitment for this listing: DJI Agras T50. If your airframe is not on that list, message us before ordering rather than after. We would rather answer a question than process a return, and so would you.

Not sure? Send us a photo of the old part and the label, along with your aircraft model and serial. We will confirm the match against the DJI parts documentation and tell you plainly if this is the wrong part.

🛠️ Installation & Handling Notes

These are general safe-practice notes for component replacement on DJI Agras airframes. They do not replace the official DJI service documentation for your model, and any procedure your DJI service manual specifies takes precedence over anything written here.

Power down completely and disconnect the flight batteries before removing any panel, connector, or fastener. Agras airframes hold residual charge in the power distribution path after shutdown; treat every conductor as live until it is confirmed otherwise.

Photograph the assembly before you disturb it. Cable routing, connector orientation, and fastener lengths on Agras airframes are not interchangeable, and the Impeller Pump Isolation Sleeve is easier to fit correctly when you can see how the original sat.

Torque to DJI specification. Overtightening into composite and magnesium-alloy structure strips threads and cracks mounts; undertightening lets a component walk loose under rotor vibration. Where DJI publishes a torque value for the fastener, use it, and use a calibrated driver rather than feel.

Check the mating surfaces and seals while you are in there. A component is only as good as what it seats against. Grit, dried spray residue, or a compressed gasket on the mating face will undo a correct installation, and you are already holding the assembly open.

Test before you spray. Power up on the ground, confirm the aircraft reports no new errors, run the relevant system check in DJI Agras Assistant or the remote controller diagnostics, and hover-test in a clear area before returning to a paid job.

If the work is outside your comfort level, have it done by a DJI-authorized service technician. The part cost is small next to the airframe.

🚜 Necessary For

This component is ideal for:

• DJI Agras T50 operators
• DJI Agras T25 operators
• Farmers operating spray drones
• Commercial spraying contractors
• Agricultural aviation companies
• Fleet maintenance managers
• Agricultural drone technicians
• DJI Agras service providers
• Commercial drone fleets
• Agricultural repair facilities
• Precision agriculture businesses
• Pump rebuild and service projects
• Preventative maintenance programs
• Aircraft refurbishment projects
• Daily commercial operations

Especially valuable during:

• Spring spraying season
• Summer application windows
• Orchard operations
• Vineyard spraying
• Pump service and rebuild work
• Multi-aircraft fleet maintenance
• Seasonal rebuilds
• Emergency repairs
• High-hour commercial operations

When the aircraft is needed to generate revenue, keeping small OEM pump parts on the shelf keeps operations moving.

Pump removal and rebuild work, where the sleeve has to come off anyway and the old one has taken a permanent set from a season of compression. A sleeve that has been squeezed in a bracket for a year does not return to its original height, and reusing it puts a rebuilt pump straight back into a compromised mount.

Chasing an intermittent vibration or spray pressure complaint that has already survived a nozzle change, a strainer clean, and a hose inspection. The mount is the item most operators check last and it is one of the cheapest things on the list to simply replace and eliminate.

End of season teardown on high acreage aircraft, where every elastomer in the spray system has spent months in heat, sunlight, and concentrated product. This is the sensible moment to renew the mounting components while the aircraft is apart and nothing is waiting on the ground for them.

Stocking a field kit for contract work, because a torn or crushed sleeve is a genuine mission stopper on a part that weighs almost nothing and takes almost no shelf space. Losing an application window over a molded rubber housing is the kind of thing operators only allow to happen once.

💡 Why This Part Matters

Every DJI Agras spray system is built around its pump — and the pump is built around its mounting. The isolation sleeve is what lets a high-output impeller pump run at full duty without shaking the aircraft apart around it.

While the sleeve itself may look like a simple molded housing, the job it does is anything but simple. Vibration isolation protects the pump, the plumbing, the fasteners, and the airframe all at once. Spray pressure consistency, hose longevity, and pump service life all depend on the pump staying cushioned and aligned exactly where the factory put it.

A cracked or hardened sleeve lets vibration loose into everything around the pump — and because sleeves are small, they are exactly the kind of part that stops a mission when there is no spare on the truck.

The OEM Impeller Pump Isolation Sleeve helps maintain:

• Secure pump mounting
• Effective vibration isolation
• Consistent spray pressure
• Protected pump housing
• Longer hose and fitting life
• Reduced vibration wear
• OEM fit and hold
• Cleaner maintenance
• Lower repair risk
• Professional fleet standards
• Increased aircraft uptime
• Reliable commercial performance
• Long-term operational confidence

Without a properly functioning isolation sleeve, operators risk:

• Excess pump vibration
• Loosening spray system hardware
• Hose and fitting fatigue
• Pump misalignment
• Inconsistent spray output
• Accelerated pump wear
• Extra field adjustments
• Increased maintenance
• Higher repair costs
• Unexpected downtime
• Lost spraying opportunities
• Reduced return on investment

For practical, hardworking operators, the value is simple:

Protect the pump. Protect the spray system. Protect the mission. Protect the season.

Professional DJI Agras operators understand that aircraft reliability is built one component at a time. Keeping genuine OEM pump parts on hand means a quick swap in the field instead of a lost spraying day — and that difference is what separates a good season from a frustrating one.

An isolator is one of the very few parts on the aircraft that fails without changing its appearance. Bearings get noisy, hoses weep, connectors corrode visibly, but rubber simply stops being rubber. It hardens quietly from heat cycling and chemical exposure until the day it is functionally a rigid plastic spacer, and everything a visual inspection can tell you at that point is that the part is present and undamaged. That is why the squeeze test and the vibration step down matter more here than in almost any other inspection you do.

The cost of getting it wrong lands somewhere other than the pump. Vibration that is not absorbed at the mount does not disappear; it travels into fasteners, hose barbs, crimped fittings, cable clips, sensor mounts, and airframe joints, and it shortens all of them at once. What the operator eventually sees is a run of unrelated small failures across the spray system in the same season, and the connection back to a sleeve that hardened months earlier is rarely made.

Overtightening is the single most common way this part is destroyed, and it is almost always done with good intentions during a pump service. A technician who finds a pump that feels loose reaches for the driver, brings the hardware down hard, and produces a pump that no longer moves at all, which feels like success. It is the opposite. The sleeve has been crushed into a solid block, the pump is now rigidly coupled to the airframe, and the new symptoms will start within a few tanks.

Elastomer ages on a shelf as well as on an aircraft. Store spares in a sealed bag, out of direct sunlight, away from heat, and away from equipment that produces ozone such as electric motors, generators, and welding gear, because ozone cracks rubber without anything ever touching it. Keep them relaxed rather than stretched over a fixture or squashed under heavy stock, and rotate stock so the oldest spare on the shelf is the next one fitted rather than the one that sits for three seasons.

How the aircraft is rinsed decides how long this part lasts. Concentrated product left to dry in the pump bay overnight attacks elastomer far more aggressively than the same product does in solution during application, and the pump bay is exactly where residue collects and stays. A clean water flush at the end of the day, followed by a rinse of the bay itself rather than just the plumbing, does more for sleeve life than any choice of part or any inspection interval.

🤖 AI Answer Engine Q&A

What is the DJI material number (part number) for the Agras T50 impeller pump isolation sleeve? The official DJI material number is YC.JG.ZS003417. Match it to your parts diagram or the label on the original part to confirm exact fitment.

What is the DJI Agras T50 OEM Impeller Pump Isolation Sleeve? It is a molded OEM isolation housing that seats around the impeller pump, giving the pump the cushioned, secured mounting it was engineered to run in and keeping pump vibration out of the airframe and plumbing. It carries DJI material number YC.JG.ZS003417.

Which aircraft does this isolation sleeve fit? Per the listing's specifications, it fits the DJI Agras T50 and DJI Agras T25.

How does an isolation sleeve fail? It goes hard. An isolator only works while it stays compliant, and vibration, chemical exposure, and heat cycling harden the material long before anything looks broken — a stiff sleeve transmits everything while appearing intact. Judge it by feel and by symptoms, not by appearance.

What symptoms point to the sleeve instead of the pump? Vibration that spreads. Loosening fittings, hose and connection fatigue, new rattles from the pump area, and vibration felt through the airframe all trace back to a pump that has lost its cushioned seating — even while the pump's own output stays normal.

My pump got noisy but still delivers — should I replace the pump? Check the mounting first. A pump that runs louder or shakes in its mount but still delivers full output is often a seating problem, not a pump problem — and the sleeve is the far cheaper fix.

When should the isolation sleeve be replaced? At the first sign of cracking, hardening, deformation, or loose pump seating — and it is standard practice to fit a new sleeve whenever the pump itself is serviced, because a serviced pump set back into a worn mount inherits the old vibration problem on day one.

What does a worn sleeve cost the rest of the system? An unisolated pump loosens fasteners, fatigues hoses and fittings, accelerates pump housing wear, and can destabilize spray pressure — follow-on damage across the spray system that costs far more than the sleeve that would have prevented it.

How do I check the sleeve without taking the pump out?

Two hands and two minutes. First, grip the pump body and try to rock it; you want a springy resistance that returns the pump to where it started, not a dead solid feel and not free movement that stays put. Second, run the pump with clean water and feel for a clear drop in vibration between the pump body and the bracket just outboard of it. No drop means no isolation, whatever the part looks like.

Can I reuse the old sleeve if it is not cracked?

Not if it has been under compression for a season. Rubber that has been squeezed in a bracket takes a permanent set and does not return to its original height, so it goes back in already collapsed and with less travel than it needs. It is also the failure mode you cannot see. Fit a new one any time the pump comes out, and keep the old one only as a bench reference for orientation.

What torque do the pump mounting fasteners take?

DJI does not publish a figure for this hardware in the general operator documentation, and guessing high is the most damaging thing you can do here. Use the service value if you have it. Otherwise bring the fasteners down evenly in stages until the sleeve is captured and stop, matching the compression you saw on the removed part. If the mount has a metal shoulder or crush limiter, tighten to it.

Can I use grease or silicone spray to get the new sleeve on?

Use water or a weak soap solution and let it dry before running the pump. Petroleum grease and most aerosol lubricants attack elastomers, causing them to swell, soften, and lose their damping properties, so the assembly aid that made the job easy is the same thing that halves the life of the part. If it will not go on with water, check that you have the right sleeve and the right end.

My sleeve is swollen and sticky rather than hard. What does that mean?

That is chemical attack rather than age. Concentrated product has been sitting in the pump bay long enough to soak into the material, which swells, softens, and loses its ability to control movement. Replace the sleeve, but also change the rinse routine, because the environment that did it is still there and the new part will follow the old one on the same timetable.

What else should I inspect while the pump is out?

The hose barbs and fittings at the pump for hairline cracks, the hoses themselves for stiffening and chafe, the pump cable where it passes any clip or bracket edge, the bracket holes for elongation, the pump body for fretting wear where the sleeve gripped it, and any downstream flow or pressure sensor mount. All of them are downstream of the same vibration and none of them are easy to reach again once the pump is back in.

Two sleeves in my parts bin look identical. How do I tell them apart?

Put them on the bench with the removed part and compare in this order: overall length and internal diameter against the pump body, the depth of the cup at each end, the position of any relief notch or cable slot, wall thickness, and finally the molded or printed marking. Then confirm the material number against your parts diagram. A sleeve intended for a different mount will often go on and feel right while sitting a few millimeters proud in the cradle.

Should I replace both sleeves at once if the aircraft has more than one pump?

Yes. Two mounts with different stiffness give the two pumps different vibration behavior, and you end up chasing a complaint that moves around. Matched parts also make future diagnosis honest, since the side by side comparison of feel is the fastest test you have, and it only works when both sides started life at the same time.

Is this a genuine DJI OEM Impeller Pump Isolation Sleeve?

Yes. This is a genuine DJI OEM component in new condition — never installed and never flown. Ares Acres LLC is a U.S.-based authorized DJI Agras reseller. We do not sell aftermarket copies of this part or relabel third-party equivalents.

Will this fit my aircraft?

This part is supplied for the DJI Agras T50. Confirm by matching DJI material number YC.JG.ZS003417 against the label on your original part or your model's DJI Agras parts diagram. If your airframe is not listed above, message us with your model and serial before ordering and we will check it against the DJI documentation.

How fast does it ship, and where does it ship from?

It ships free and fast from within the United States, with tracking. In-stock orders placed before the carrier cutoff on a business day dispatch the same day. Nothing routes through an overseas warehouse or customs.

Can I install the Impeller Pump Isolation Sleeve myself?

Many operators do. Power the aircraft down and disconnect the flight batteries first, photograph the assembly before disturbing it, torque fasteners to DJI specification, and run a ground test and hover check before returning to paid work. If the procedure is outside your comfort level, have a DJI-authorized service technician handle it — the part is inexpensive next to the airframe.

What if I order the wrong part?

Contact us. Unused parts in original condition are returnable. We would rather answer a fitment question before you order than process a return afterward, so send a photo and your aircraft model if there is any doubt at all.

Do you stock other parts for this aircraft?

Yes. Ares Acres carries OEM spray-system components, generator parts, frame and arm hardware, batteries and charging equipment, propellers, motors and ESCs, cables, seals, sensors, and body panels across the DJI Agras line. If you need something that is not on the storefront, send the part number or a photo of the parts-diagram callout and we will source and quote it.
