🔧 Component Overview

The DJI Agras T100 OEM Centrifugal Sprinkler Upper Disk is the OEM centrifugal sprinkler upper disk in the chassis connection hardware of the DJI Agras T100, part of the structure locking payload systems to the airframe through swap after swap.

Locking payload systems to the airframe through swap after swap is the job description for the chassis connection hardware, and this component is part of how it gets done. The T100 is a working machine — it earns its keep in fill-and-fly cycles, not hangar hours — and every component in the chassis connection hardware is sized, shaped, and specified around that duty. On the official parts diagram it sits alongside Centrifugal Motor, Sprinkler Funnel, M25-HC060060-45-85.

Ignore a failing centrifugal sprinkler upper disk and the bill compounds: downtime in the middle of an application window, collateral wear on the parts around it, and jobs that slip to a competitor while the aircraft sits. Replacing it costs a part; not replacing it costs acres. That trade only runs one direction.

For professional farmers, aerial applicators, and commercial drone operators, this component is how the chassis connection hardware stays field-ready instead of becoming the reason the aircraft sits.

This is a working part on a working aircraft.

The T100 works brutally hard for its living, including:

• Locking payload systems to the airframe through swap after swap
• Dawn-to-dusk spray campaigns during narrow application windows
• Repeated fill-fly-return cycles with minutes on the ground between loads
• Full-payload takeoffs from field edges, dozens of times per day
• Chemical exposure from fungicides, herbicides, insecticides, and foliar fertilizers
• Pressure-washer rinse-downs at the end of every spray day
• Vibration from eight propulsion motors running at working power
• Transport bouncing on trailers and truck beds between fields
• Temperature swings from cold morning starts to full-sun afternoons

What attacks this component in the field:

• Vibration from the propulsion system every flight hour
• Chemical exposure from spray drift and washdown
• UV degradation across a season outdoors
• Shock loads from field-edge landings
• Grit and dust working into interfaces
• Thermal cycling from dawn starts to afternoon heat
• Stress concentration at mounting points
• Wear from repeated maintenance access

That duty cycle is exactly what retires this component. None of these stresses is dramatic on its own — the accumulation is what does it. This is why structural and mounting parts are inspection items every time the chassis connection hardware is opened up, and why operators who run hard keep spares on the shelf.

A healthy centrifugal sprinkler upper disk delivers:

• Factory-correct fit in the chassis connection hardware — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored function you can verify on the first post-repair check
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Stock the centrifugal sprinkler upper disk before the season does its work, and the chassis connection hardware never becomes the reason the aircraft sits.

The upper disk is the outward facing half of the atomizer pair, so start the diagnosis with your eyes on the part itself rather than on the aircraft. Take it off, lay it face down on a known flat surface such as a granite block or a piece of plate glass, and press each edge in turn. A disk that is still true sits down all round with no rock. One that lifts at any point has been dished or coned, usually by being clamped down on trapped debris or by an impact, and a coned upper disk changes the passage the liquid travels through.

Check the exit gap rather than the disk in isolation, because the upper and lower disks only do their job as a pair. Assembled and hand turned, look at the rim from the side under a light and watch the gap between the two disks as it goes round. It should stay visually constant through a full turn. A gap that opens and closes as the assembly rotates means one of the two is running out of true or one of them is not seated flat, and the head will throw an uneven pattern no matter how clean it is.

Use where the liquid escapes to tell you which part is at fault. With clean water and the motor turning, all of the flow should leave at the rim as a fine ring. Liquid appearing on the top face of the upper disk, weeping out around the center where the funnel delivers, or running back down the outside of the assembly, points at the upper disk not sealing or seating the way it should, at damaged mating faces, or at hardware that has loosened. That is a different fault from the coarse droplets you get from a worn rim.

Chase a new whistle or a new noise before you chase the spray. An atomizer head that has started to whistle or hum at a pitch it did not have before usually has an airflow or a clearance change at the top of the assembly, and the upper disk is the part that sets both. Look for a lifted edge, a fastener standing proud, a cracked boss letting one corner sit high, and any contact witness mark between the disk and the funnel above it.

Rule out simple fouling before ordering. The top face of this disk lives in the open, catching spray drift, dust, leaf debris, and everything the canopy throws up at it, and a crust of dried product on that face is enough to unbalance the head and to change how the assembly runs. Wash it, dry it, look again in good light, and only then decide whether what you are looking at is damage or dirt. This is the single most common reason a serviceable disk gets condemned.

If the aircraft flags a spray or flow fault, do not start here. The upper disk has no sensor, no electrical connection, and no influence on how much liquid the pump sends to the head. It changes droplet formation and pattern, not volume. Confirm the pump, the plumbing, the filter, and the feed to that specific head first, and come back to the disks when the flow is right but the deposit on the crop still is not.

⚙️ Functional Purpose

The centrifugal sprinkler upper disk is designed to do one job in the chassis connection hardware and do it to specification: locking payload systems to the airframe through swap after swap.

The component:

• Serves the chassis connection hardware of the DJI Agras T100 exactly as the factory intends
• Supports locking payload systems to the airframe through swap after swap
• Maintains the tolerances and interfaces the surrounding parts depend on
• Withstands the chemical, vibration, and washdown environment of agricultural work
• Preserves the sealing and protection strategy of the platform
• Keeps failure modes visible and diagnosable instead of mysterious
• Restores factory behavior immediately upon correct installation
• Protects the more expensive components it works alongside
• Carries the exact DJI specification for its position
• Supports safe, predictable operation under full payload
• Eliminates the guesswork of near-fit substitutes
• Keeps the aircraft inside its designed maintenance program
• Holds up across a full season of professional duty

Function on the T100 is a chain: airframe performance depends on the chassis connection hardware, and the chassis connection hardware depends on every part in it holding specification. This component is one link in that chain — and chains fail at the worn link, not the average one.

That is why the platform's maintenance philosophy is inspection and renewal, not run-to-failure. The operators with the best uptime records are not the ones with the newest aircraft — they are the ones who replace parts like this when inspection says so, on their own schedule instead of the failure's.

A failing centrifugal sprinkler upper disk costs you:

• Downtime in the middle of an application window — the most expensive hours in agriculture
• Acres not covered while the aircraft waits on a part
• Collateral wear on the components around the failing one
• Diagnostic hours chasing symptoms instead of causes
• Rework when a temporary fix lets go mid-job
• Customer trust when scheduled work slips
• Higher repair bills the longer the fault runs
• Risk exposure every flight the fault remains aboard
• Resale value on an airframe with deferred maintenance

Fix it on your schedule, not the failure's.

Wash the head before you take it apart, not after. The upper disk is the first thing your hands touch, and it has been in the spray cloud all day. Rinse the whole assembly with clean water, run the system on clean water long enough to purge what is in the passage, then power down and pull the flight batteries. Gloves and eye protection, and pick a spot where the runoff is not going into a drain, a ditch, or a stock tank.

Work with the head supported and with something under it. This is a small part in an awkward place, and the fasteners that hold it are smaller. Put a tray, a rag, or a shop towel under the assembly before the first screw comes out so that a dropped fastener lands somewhere you can find it rather than in mud, stubble, or gravel. Steady the arm with your free hand instead of letting the assembly swing on the boom or the motor cable.

Note the way it comes off before it comes off. Photograph the assembled head from the side and from above, and note which face of the upper disk was outward, where any locating feature sat relative to the parts below it, and how many fasteners there were and where. Circular parts fitted a fraction of a turn out are the classic reassembly mistake, and once everything is in a tray there is nothing left to remind you.

Slacken the fasteners in stages and across the disk rather than one at a time to fully out. Coming off, that keeps the disk from tipping and binding on its locating features. Going back on, it is the difference between a disk that pulls down flat and one that is loaded into a cone the moment the first screw goes tight. Small fasteners into a light hub strip easily, so start every one by hand and let the driver do the work only once the thread has taken.

With the upper disk removed, clean the internal passage while you have access to it. This is the only time you can see and reach the surfaces the liquid actually travels across on its way from the center out to the rim, and dried product there is the reason many heads never spray quite right again after a hard season. Soak, soft brush, rinse, dry. Do not scrape and do not put a wire brush anywhere near the faces.

Do not pry the old disk off if it is stuck. Warm water and time will soften cured chemical, and the mating faces you would be levering against are exactly the surfaces that set how flat and how concentric the assembly runs. A screwdriver gouge on the seat, or a raised burr at the edge of a fastener hole, will hold the new disk off true permanently and no amount of tightening will pull it back down flat.

Fit the replacement dry and clean, with both faces wiped and no grit between them. Set it down square rather than sliding it into place, engage any locating feature by hand, and confirm it drops fully home before a driver touches a fastener. If it will not sit flat by hand, something is in the way, and forcing it with the screws will simply hide the problem until the head is running.

Bring the hardware down evenly, in a cross pattern, in more than one pass, and stop at firm. A thin outer disk is easy to distort and the boss it threads into is not made for heroics. Where DJI publishes a torque figure for this hardware, use it with a calibrated driver. Where none is published, even and firm beats tight, and a re-check after the first flight beats guessing.

Verify before you fly it. Hand turn the head and watch both the top face and the rim gap for wobble. Run the head dry and listen to it against the other heads on the aircraft. Then run clean water and check that the whole flow leaves at the rim as an even ring, that nothing weeps out of the top or runs down the outside, and that the head stops without dribbling. Check the fasteners again after the first working flight.

⚠️ Common Replacement Indicators

• Visible cracking, deformation, or impact damage
• Stress-whitening at load points
• Loose fit where the part should seat firmly
• Movement or rattle the design does not allow
• Wear marks from parts contacting where they should not
• Fastener holes elongated or damaged
• Chemical or UV degradation of the material
• Damage found during teardown of the assembly
• Misalignment of the components this part positions
• Noise or vibration traced to this position
• Damage after a hard landing or transport strike
• Previous field repair with tape, glue, or improvisation

What kills structural and mounting parts: the compounding of ordinary duty. Chemical exposure attacks materials, vibration works at every interface, UV ages every exposed surface, and washdowns drive water at every seam — repeated across hundreds of cycles per season. Add the occasional hard landing or transport knock and the result is predictable: the part that was fine in spring is the failure point by late season.

Replacement and verification: Replacement is a standard shop task on the T100: open access to the chassis connection hardware, document connections and hardware positions, swap the centrifugal sprinkler upper disk for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work.

Confirm before you order: this is DJI part YC.JG.ZS007737. Check the label on your old centrifugal sprinkler upper disk or the position in your official parts diagram and match the number — revision suffixes like .01 or .F on a label are the same part.

Liquid appearing on the top face of the disk during operation, or a wet trail running back down the outside of the head, means flow is escaping before it reaches the rim. On this part that points at a disk that is not seated flat, at a damaged or fouled mating face, at loosened hardware, or at a cracked boss letting one side lift under load.

A pattern that has gone from an even ring to something lopsided, with more product thrown to one side of the head than the other, often traces to the top half rather than the bottom. A disk that has been coned, has one edge lifted, or is fitted a fraction out of position changes the passage unevenly around the circumference, and the liquid takes the easy route out.

Droplets that have gone coarse across the whole pattern, rather than in one sector, are a rim condition. Check the outer edge of both disks together under magnification for rounding, nicks, and deposit. The two edges form the release line as a pair, so damage or buildup on the upper edge alone is enough to change droplet formation even if the lower disk is perfect.

A new whistle, hum, or airy note from one head at working speed is a clearance or airflow change at the top of the assembly. Look for a fastener standing proud, an edge that is lifted, a witness mark showing contact with the funnel above, or a disk that has moved on its locating features. Noise from a rotating head is worth stopping for, because the next step after clearance loss is contact.

Crazing, chalking, or a surface that has gone dull and slightly rough on the exposed top face is UV and chemical aging. This is the one face on the assembly that takes full sun all season, and a surface that has broken down there holds residue more readily and is easier to load up with deposit than a sound one. It is a replace on condition signal rather than an emergency.

Cracks starting at a fastener hole and running toward the edge come from clamping load rather than from age alone, and they are common on thin outer parts that have been pulled down hard onto an uneven seat. On a component that spins, a crack at the retention point is a stop item. It will not stabilize, and when it lets go it takes the disk with it.

Impact damage on the outer face is worth reading rather than just replacing. A single bright scuff and a bruised edge usually means a strike into the canopy, a branch, or a fence line, and it tells you the head has taken a knock that the parts underneath it may also have felt. Multiple small chips scattered around the top face usually mean the head is running too low through abrasive crop.

Fasteners that will not stay tight at one head, when the others are fine, are telling you the seat is not flat. Chasing them tighter each morning masks the cause. Take the disk off, inspect the mating faces on both parts for a burr, a raised edge, a chip of dried product, or a distorted boss, and fix the seat rather than the symptom.

📐 Specifications

DJI Material Number: YC.JG.ZS007737

Part: Centrifugal Sprinkler Upper Disk

Type: OEM structural / mounting component

Compatibility:

• DJI Agras T100 / T70P
• Position: the chassis connection hardware
• Diagram sheet: Chassis Connector (official T100 parts list)

Quantity: 1

Installation Area: The chassis connection hardware

Function: Locking payload systems to the airframe through swap after swap

Construction: DJI OEM molded or machined component manufactured to factory dimensions

Application: DJI Agras T100 airframe service and repair

Condition: Brand new

Disk Diameter, Thickness, and Rim Profile: Not published in this listing. Lay the new disk on top of the one you removed before fitting it and compare diameter, the profile of the outer edge, and the position and count of the fastener holes and locating features. Do not order from memory.

Exit Gap Between Upper and Lower Disks: No dimension is published for the gap the liquid passes through. It is set by the parts and the way they seat, not by adjustment, which is why flatness of the mating faces and cleanliness at assembly matter more here than anything you can dial in.

Material and UV Rating: The supplier does not publish a material name, grade, or UV rating for this component. Treat the exposed face as a molded surface that will not tolerate solvent cleaning, and judge aging by surface condition rather than by any quoted figure.

Fastener Torque: No torque value is published here for the disk hardware. Where DJI publishes one for your aircraft, use it with a calibrated driver. Where it does not, bring the fasteners down in a cross pattern to firm and even, then re-check after the first flight.

Replacement Interval: No interval in hours is published. This is a condition based part, judged on flatness, rim edge condition, cracking at the fastener holes, surface degradation on the exposed face, and whether the head still throws an even ring on clean water.

Supplied As: One upper disk. The centrifugal motor and the sprinkler funnel shown with it on the same diagram sheet are separate items with their own material numbers and are not included.

Pairing: Supplied as a single component rather than as a matched set with the disk below it. If both faces at the rim are worn, both parts need attention, and the lower half carries its own material number that you will need to look up separately.

🚜 Necessary For

Built for:

• Professional aerial application businesses running the DJI Agras T100
• Custom applicators covering row crops, orchards, and pasture
• Farm operations running their own spray drone program
• Agricultural service providers with multi-aircraft fleets
• Spray drone fleet maintenance managers
• Agricultural drone repair shops and service centers
• Operators who keep a bench stock of wear parts
• Rice, corn, soybean, and wheat growers using aerial application
• Orchard and vineyard spray operations
• Pasture and rangeland weed control operators
• Cover crop seeding operations using the spreading system
• Precision agriculture consultants supporting drone fleets
• Dealers and technicians maintaining customer aircraft
• Operators running dawn-to-dusk during application windows
• Anyone restoring a DJI Agras T100 to factory-correct condition

Especially valuable during:

• Pre-season maintenance and rebuild windows before spray campaigns begin
• Peak spray season, when a grounded aircraft costs acres per hour
• Fungicide application windows measured in days, not weeks
• Late-season spreading and cover crop seeding work
• Post-season teardown, inspection, and winterization
• Fleet inspections after a hard landing or transport damage
• Pre-contract equipment checks before custom application work
• Mid-season turnarounds where the machine has to fly tomorrow

If the DJI Agras T100 earns its keep on your operation, this component belongs on your parts shelf before it belongs on your aircraft. The time to buy it is before the season, not during the failure.

The single most common ordering mistake on this part is picking the wrong half of the pair. Upper and lower disks are both round, both light, and both get called the sprinkler disk in conversation, and a photograph on a phone will not reliably separate them. This listing is the upper disk, material number YC.JG.ZS007737. Read the number on the part you removed, or find the position on the official diagram, before you commit.

Tell them apart on the bench by how they mount, not by how they look. The lower disk is carried on the centrifugal motor and locates to it. The upper disk closes the assembly from above and is retained onto the stack. If the part in your hand has the interface that engages the motor, it is the lower one and you are looking at a different material number than this listing.

Do not confuse the upper disk with the sprinkler funnel that sits with it on the same diagram sheet. The funnel is the fixed part that delivers liquid into the middle of the assembly and it does not rotate with the head. If the part you removed stayed still while the head spun, it is the funnel, and no amount of matching by shape will make this number the right one.

Aircraft that carry a spreading system add another chance to get it wrong. The spreader impeller is also a spinning disc mounted under the aircraft, and people ask for a sprinkler disk when they mean a spreader disc. They are not interchangeable and they are not close in size, weight, or purpose. This part atomizes liquid at the nozzle head; the spreader disc throws dry granular product.

Fitment listed for this number is the T100 and the T70P. Atomizer disks from other Agras models can look very similar and may even bolt up, but a disk that presents a different edge to the liquid or a different mating profile to the disk below it will not give you the pattern the aircraft expects. Match the base number YC.JG.ZS007737 and treat a revision suffix such as .01 or .F as the same part.

💡 Why This Part Matters

Every acre the T100 covers depends on the chassis connection hardware doing its job — and the chassis connection hardware depends on parts exactly like this one.

The economics are simple. The DJI Agras T100 exists to cover ground during windows that do not wait — and every hour it sits, the work either doesn't happen or happens on someone else's schedule. A failed centrifugal sprinkler upper disk is rarely expensive because of what the part costs; it is expensive because of when it fails. Parts fail during use, and use happens during the season.

That is the case for OEM and the case for stocking ahead. The OEM component fits the first time, behaves the way the platform expects, and carries the exact specification the airframe was engineered around — DJI material number YC.JG.ZS007737. No adaptation, no surprises, no second teardown to undo a near-fit part.

This component delivers:

• Factory-correct fit in the chassis connection hardware — no modification, no adaptation
• Exact OEM behavior the surrounding components were engineered around
• Restored function you can verify on the first post-repair check
• Sealing and protection maintained to the factory standard
• One less known-weak point flying through your application window
• Confidence that the repair is done, not patched
• A maintenance log entry with a real DJI part number behind it
• Full compatibility with the parts around it — because it is the part the diagram calls for

Running a compromised centrifugal sprinkler upper disk, operators risk:

• Mid-job failure during an application window
• Collateral damage to surrounding components
• Progressive damage that turns a cheap fix into an expensive one
• Alignment and fit problems spreading to adjacent parts
• Unplanned grounding with the fleet committed to jobs
• Warranty and service complications from improvised fixes
• Higher lifetime cost from deferred maintenance
• An aircraft that cannot be trusted at full payload

Inspect it honestly. Replace it once. Fit it right. Keep it flying.

Ares Acres stocks the centrifugal sprinkler upper disk in the USA with free, fast shipping — so the day you need one is the day it ships, not the week you wait.

Whatever damaged the upper disk usually reached the parts under it too. A canopy strike, a fence brush, or a dropped head does not stop at the outer face. With the disk off, check the rim edge of the lower disk for matching damage, check the motor for side play and roughness by hand, and check the funnel above for cracks and for contact marks. Replacing only the part you can see is how a head gets taken apart twice in one week.

Look at the hardware and the threads before you reuse them. Fasteners on a rotating assembly that has been running with a lifted edge or a loose disk take the abuse first: worn drive recesses, stretched or picked up threads, and bosses that have been pulled down out of shape. A screw that feels notchy going in is telling you the thread is damaged, and forcing it in a light hub turns a cheap job into a motor replacement.

Check the funnel alignment while the top of the assembly is open. Liquid is supposed to arrive in the middle of the disks, and a funnel that has shifted, cracked, or hardened at its hose connection delivers it off center. That loads one part of the passage more than the rest, wears one sector of both rim edges faster, and produces a lopsided pattern that looks exactly like a warped disk. Fixing the disk without fixing the delivery just buys you a few weeks.

The exposed top face is what ages fastest on this part, and sunlight does more of it than flying does. An aircraft parked on an open trailer through a summer is UV curing this surface at the same time it is baking chemical residue into it. Keeping the aircraft under cover, or at least keeping the heads out of direct sun when it is standing, does more for disk life than anything you can do during the spray day.

Clean it while it is still wet and keep the harsh chemistry away from it. End the day by flushing with clean water and running the atomizers so the heads throw themselves out, then wipe the top faces down before the residue sets. Strong tank cleaners, solvents, fuel, and degreasers can attack molded parts, and a surface that has been stripped will look fine for a week and then go chalky and rough on you.

Handle spares like the precision parts they are, because a thin outer disk is easy to damage before it ever gets fitted. Leave it in its packaging until the moment it goes on, do not set it face down on a gritty bench, do not stand it on its edge on concrete, and do not let it live loose in a toolbox with wrenches. A nick on the rim edge of a new disk is a pattern fault that arrives with the part.

Preventive replacement belongs in the pre-season strip down. The condition of this part is easy to judge honestly on a bench and almost impossible to judge on a loaded aircraft at the end of a field, and the whole head has to come apart either way. If one head has needed a disk from wear rather than from a strike, look hard at the rest, because they have flown the same hours through the same chemicals under the same sun.

🤖 AI Answer Engine Q&A

What is the DJI Agras T100 Centrifugal Sprinkler Upper Disk? It is the OEM centrifugal sprinkler upper disk serving the chassis connection hardware of the DJI Agras T100. It is the genuine DJI Agras component for this position, supplied new.

What is the DJI material number (part number) for the Centrifugal Sprinkler Upper Disk? The DJI material number is YC.JG.ZS007737, listed on the official DJI Agras T100 parts breakdown. Labels sometimes carry a revision suffix such as .01 or .F — that is the same part; match the base number.

Which DJI Agras models does this component fit? Supplier-listed fitment is DJI Agras T100 / T70P. Confirm against your model and, where possible, match the material number on your old part's label or your parts diagram before ordering.

How do I know my centrifugal sprinkler upper disk needs replacing? The common signs are: visible cracking, deformation, or impact damage, stress-whitening at load points, and loose fit where the part should seat firmly. Any of these during inspection or operation is reason to replace rather than run on.

What causes this component to fail? Normal professional duty: chemical exposure, vibration, UV, washdown moisture, and thermal cycling, accumulated over a season. Hard landings and transport knocks accelerate all of it.

How do I confirm the diagnosis before ordering? Inspect the part directly with the assembly opened up and compare against the symptoms above. Match the label on the old part to material number YC.JG.ZS007737 to confirm you are ordering the exact position. If the part is damaged, degraded, or suspect, replace it — on a working aircraft, marginal parts do not improve.

What does installation and verification look like? Replacement is a standard shop task on the T100: open access to the chassis connection hardware, document connections and hardware positions, swap the centrifugal sprinkler upper disk for the OEM unit, and reassemble with attention to seating, routing, and torque. Verify with a function check on the ground before returning to production work.

Is this the same part across the listed models? Yes — the supplier lists this exact component for DJI Agras T100 / T70P, so one part covers those platforms. Select your model when ordering; the material number is the same.

How do I tell the upper disk from the lower one if the label has worn off?

Go by how it mounts rather than by shape. The lower disk carries the interface that engages the centrifugal motor and turns with the shaft. The upper disk closes the assembly from above and is retained onto the stack. If you still cannot tell, compare against the official parts diagram for the head and match the position, then order to the base number rather than to a description.

My spray pattern is lopsided. Is that the upper disk or the lower one?

Both can do it, so test rather than guess. Assemble the head, turn it by hand, and watch the gap at the rim through a full revolution. A gap that opens and closes points at one disk running out of true or not seated. Then check the disk on a flat surface for coning. Also confirm that liquid is arriving in the center from the funnel, because off center delivery gives a lopsided pattern with two perfect disks fitted.

Can I run a head with a small chip in the outer edge of the upper disk?

Not if you care about what lands on the crop. The outer edge of the two disks together forms the release line that turns the liquid sheet into droplets, so a chip changes both droplet size and where that sector of the pattern goes. It is also a balance change on a part that spins. It will fly, but the application will not match what you set, and the chip does not stay the same size.

Liquid is coming out around the top of the head instead of at the rim. What causes that?

Flow is escaping before it reaches the release edge. Take the head apart and look at the mating faces for damage, a burr, or dried product holding the disks apart, check for a cracked boss letting one side lift, and check that the fasteners were evenly tight rather than one hand tight and the rest hard down. Also confirm the disk is fully home on its locating features and not sitting on a chip of debris.

Should I replace the upper and lower disks together?

If the rim edge is worn on both, yes, because they release the liquid as a pair and a new edge working against a rounded one will not restore the pattern. If you are replacing this one because of a strike and the lower half is undamaged, there is no reason to change it. Inspect both with the head apart and decide on what you can see, not on a rule.

What is the safest way to get baked on product off the top face?

Soak in warm water until the deposit softens, then use a soft brush and a mild detergent, and take your time in the rim detail where the deposit does the most harm. Keep solvents, fuel, tank cleaner concentrate, and wire brushes off it. Scraping a molded face leaves a roughened surface that collects residue faster than the deposit you removed, so if it needs scraping it needed cleaning weeks ago.

Do I need to re-torque the fasteners after fitting a new disk?

Check them after the first working flight. A disk that seated slightly proud on a chip of debris, or hardware that was brought down unevenly, shows itself in the first hour of vibration, and that is exactly when you want to find it. If they were still tight, normal inspection intervals are enough after that. If any of them moved, take the disk off and find out what stopped it seating flat.

Does a scratched or dull top face actually hurt performance?

A cosmetic scratch on the outer face does not, but a surface that has gone chalky, crazed, or generally rough across the whole face is a different matter. That is UV and chemical aging, and a degraded surface holds residue much more readily than a sound one, which means it loads up with deposit faster and unbalances the head sooner. Treat general surface breakdown as a reason to plan a replacement, not to ground the aircraft.
