🔧 Component Overview

The DJI Agras T100 OEM Spray Lance Bottom Shell is the OEM spray lance bottom shell in the mist spray lance of the DJI Agras T100, part of the structure carrying atomized spray hardware into the airflow beneath the rotors.

Carrying atomized spray hardware into the airflow beneath the rotors is the job description for the mist spray lance, 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 mist spray lance is sized, shaped, and specified around that duty. On the official parts diagram it sits alongside Mist Sprinkler Support Rod, Mist Spray Lance Connector, Centrifugal Sprinkler Adapter Cable (Optional).

Ignore a failing spray lance bottom shell 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 mist spray lance 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:

• Carrying atomized spray hardware into the airflow beneath the rotors
• 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 mist spray lance is opened up, and why operators who run hard keep spares on the shelf.

A healthy spray lance bottom shell delivers:

• Factory-correct fit in the mist spray lance — 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 spray lance bottom shell before the season does its work, and the mist spray lance never becomes the reason the aircraft sits.

Fluid appearing under the lance almost never means the shell itself is leaking, and getting that wrong costs you a part and leaves the fault in place. The shell is a cover: it encloses the plumbing and the atomizer hardware, it does not carry pressure. Liquid that collects inside will find the lowest opening and drip from it, so the visible wet spot is where the shell drains, not where the leak started. Take the shell off and find the actual source before you order anything.

Run a clean water test with the assembly open. With the aircraft supported and the system filled with clean water only, pressurize on the ground and watch the inside of the lance under good light while somebody works the spray system. You are looking for a fitting that beads up, a hose that weeps at a clamp, or a seep at a joint. A leak found this way takes two minutes to identify and tells you whether the shell needs to be part of the order at all.

Judge the shell on its own faults, which are structural rather than hydraulic. Off the aircraft, set it on a flat bench and see whether it sits without rocking. Offer it up to its mating half dry, with no fasteners, and look for a gap at the seam or a corner that stands proud. A shell that has been distorted by impact or heat will not close evenly again, and every fastener you tighten to pull it down is loading a part that is fighting you.

Hunt hairline cracks with cleanliness and light rather than with your eyes alone. Wash the shell, dry it completely, then flex it gently by hand with a strong light held behind and across the surface at a low angle. Cracks open under flex and show as a moving dark line. The other reliable tell is a wet line that keeps reappearing on an otherwise dry shell, because a crack holds fluid and weeps it back out long after the surface around it has dried.

Read the whitening, because it tells you what happened. Stress whitening that radiates from a single point in a starburst is impact damage, and the shell took a hit there. Whitening that appears at several fastener bosses at once, with no impact mark anywhere, is the material telling you it has been overtightened or that it has aged and is no longer flexing the way it did. The first is a one-off. The second says the rest of the shell is close behind.

Check the fastener bosses before you decide the shell is serviceable. Run each fastener in by hand and feel for one that turns forever without pulling down, or one that tightens and then goes slack again a moment later. Either behavior means the insert or the thread in that boss has failed, and a cover that cannot be clamped at one of its points will chatter in the airflow, work the surrounding material, and start a crack from that boss.

Separate a shell problem from a mounting problem. If the lance itself moves, rattles, or sits at a different angle than it used to, check the hardware that attaches the lance to the aircraft before assuming the shell is at fault. A cover cannot hold an assembly in position that its mounts have let go of, and fitting a new shell to a loose lance mount gives you a new part that develops the same cracks in the same places.

⚙️ Functional Purpose

The spray lance bottom shell is designed to do one job in the mist spray lance and do it to specification: carrying atomized spray hardware into the airflow beneath the rotors.

The component:

• Serves the mist spray lance of the DJI Agras T100 exactly as the factory intends
• Supports carrying atomized spray hardware into the airflow beneath the rotors
• 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: atomized spray system performance depends on the mist spray lance, and the mist spray lance 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 spray lance bottom shell 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.

Make the assembly safe to open before a tool touches it. Drain the tank, flush the spray system through with clean water, and relieve any pressure in the lines, then power the aircraft down and disconnect the flight batteries. The inside of a lance holds concentrate residue that has never been diluted by anything, so wear gloves and eye protection and work somewhere the rinse water goes where you intend it to rather than into a shop drain.

Disconnect at the connectors, not by pulling on anything. Atomizer leads and any sensor wiring inside the lance are released by their latch, and a lead that is tugged to free it damages the pin, the crimp, or the strain relief in ways you will not see until an intermittent fault appears in the middle of a job. Support the weight of the lance while you work rather than leaving it hanging on a hose or a harness.

Photograph the inside before anything moves. Record how the hose is routed, which side of each bracket the wiring passes, where every clip sits, and how much slack there is at each end. Cover assemblies like this one are also the thing that holds a loom in place, so the routing you find is the routing the designer intended, and reproducing it from memory a week later is how a hose ends up rubbing against a fastener head for a season.

Back the fasteners out slowly and keep the driver square and fully seated. Fasteners into plastic bosses do not tolerate an angled driver, and a rounded head at the bottom of a lance is a much bigger job than the one you started. If a fastener spins without lifting, the insert is turning in its boss: press the shell down against it to add friction and ease it out rather than driving harder, and note that boss as damaged so you can check it against the new part.

Split the seam evenly with a plastic trim tool and nothing sharper. Work all the way around the perimeter a little at a time rather than levering one corner up. A screwdriver at the seam gouges the mating flange, and the flange is the surface that has to close cleanly against the other half, so a nick there becomes a permanent gap that lets spray mist and washdown water inside. Watch for a seal at the seam and for anything captive that can drop out as the halves part.

Clean and inspect the area while it is open, because you will not have this access again for a while. Wash out settled residue, check that any drain or weep path is clear rather than plugged with dried product, and look over every fitting, clamp, and length of hose in the lance for swelling, hardening, or a witness mark where something has been rubbing. Check the mating half for cracks at the same time, since the two shells share every load.

Dress the wiring and hose first, then close it. The single most common mistake on any clamshell cover is trapping a wire or a hose in the seam. It closes, it looks right, and the item inside is being pinched every time the assembly flexes until the insulation or the hose wall gives up. Route everything into its clips, then hold the shell up to the seam and look around the whole perimeter before a single fastener goes in.

Start every fastener by hand and pull the shell down evenly. Get all of them started with fingers, confirm the seam is closing uniformly with no corner standing proud, then tighten progressively around the perimeter rather than running each one home in turn. Use the DJI torque figure with a calibrated driver where one is published. Into plastic bosses, the failure mode of extra tightness is a stripped insert or a crack you have just built into a new part.

Verify with water before you verify with chemical. Refill with clean water, pressurize the system on the ground, and check the seam and every fitting for weeping while the system runs. Run the atomizers and listen for any buzz or chatter that was not there before, which is the sound of a cover that is not clamped evenly. Confirm the aircraft reports no spray system errors, then do a short test pass on water and inspect the lance again before it goes back on paid work.

⚠️ 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 mist spray lance, document connections and hardware positions, swap the spray lance bottom shell 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.ZS006807. Check the label on your old spray lance bottom shell 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 pooling on the underside of the lance after every job, on an assembly whose fittings all look dry, means fluid is collecting inside the shell and escaping at its lowest opening. Treat that as a leak inside the enclosure rather than as a leak in the cover, and understand that whatever is leaking has been sitting against wiring, connectors, and hardware in the meantime. The pooling is the last symptom in the chain, not the first.

A buzz, a chatter, or a new note from the lance area in flight is usually a cover that is no longer clamped at every point. Airflow beneath the rotors is not gentle, and a shell held down at all but one boss will vibrate against the assembly at that corner. The noise itself is harmless. What it is doing to the material around the loose boss is not, and it is a crack in the making that gets worse every hour it flies.

Fasteners that will not come up to a firm stop, or that need retightening after every few jobs, mean the bosses are giving up rather than the fasteners loosening. Once one insert has spun, the clamp load redistributes onto its neighbors, so the failures come in sequence rather than one at a time. A shell that has needed two bosses repaired is telling you the rest of them are working harder than they were designed to.

A chalky surface that leaves powder on your hand, or a shell that has gone noticeably faded and dull compared to the rest of the aircraft, is a polymer that has been aging in sunlight and chemistry. The color change is cosmetic. The loss of flexibility underneath it is not, and a shell in that condition will crack from an impact it would have shrugged off when it was new. Aged material also cracks first at the bosses, where the deflection concentrates.

A visible gap at the seam that will not pull closed no matter how the fasteners are tightened has one of two causes, and both matter. Either something is trapped in the seam, in which case a wire or a hose is being crushed, or the shell has been distorted and no longer matches its mating half. Forcing it closed with fastener tension puts a permanent load into a part that is already unhappy and hides a pinched item where you will not find it.

Dried product, mud, or chaff packed inside the shell is not just untidy. It holds moisture and chemical against everything in there, it blocks the drain paths so the next leak has nowhere to go, and it adds mass in an area that is being vibrated constantly. Finding a packed shell also means the enclosure has not been sealing, so the entry path is worth locating while you have it open.

A change in how the spray behaves at one position, with the pump, the flow readings, and the nozzle hardware all checking out, is worth taking to the lance structure. This part carries atomized spray hardware into the airflow beneath the rotors, so anything that lets that hardware sit at a slightly different angle or vibrate in place changes what leaves the aircraft. Structure is the last thing operators check for a pattern complaint and occasionally it is the answer.

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

Application: DJI Agras T100 atomized spray system service and repair

Condition: Brand new

Dimensions, Wall Thickness, and Weight: Not published in this listing. Confirm the part by DJI material number YC.JG.ZS006807 against the label on the shell you removed or the callout on the official parts breakdown rather than by measuring.

Material and Chemical Resistance Rating: Not stated by the supplier. No polymer type or chemical compatibility list is published, so do not assume a shell will tolerate a solvent, a chlorinated cleaner, or an ammonia based product on the basis of what other plastics survive.

Fastener Torque and Count: Not published here. Use the DJI figure with a calibrated driver where one exists. Where none is published, pull the shell down evenly until the seam closes and stop, because these fasteners land in plastic bosses and extra tightness strips inserts rather than improving the seal.

Seal or Gasket Included: Read the Package Includes list on this listing, which is the authority on what ships. If your assembly uses a seal at the seam and it is not among the listed contents, inspect the existing one and source it separately rather than reusing a seal that has taken a set.

Mating Half: Not included. The top shell of the mist spray lance is a separate component with its own DJI material number. Inspect it while the assembly is open, since both halves share every impact and every clamp load.

Service Classification: Structural cover. Replaced on condition after impact, cracking, stress whitening at the fastener bosses, a distorted seam, or failed bosses, rather than at any published interval.

• 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 part most often ordered by mistake in place of this one is the mating top shell of the same lance. They are described almost identically, they appear next to each other on a parts breakdown, and on a shelf they look like two halves of the same thing because that is exactly what they are. They carry different material numbers. Before ordering, hold the damaged half in your hand, find its label, and match the number rather than deciding by which way up it was sitting on the aircraft.

Do not confuse the lance shell with the atomizer housing or nozzle cover that sits at the spray hardware itself. The shell is the enclosure along the lance that carries and protects the plumbing and wiring, while the atomizer housing is the much smaller part immediately around the spray head. A complaint about droplet size or pattern usually belongs to the atomizer end of the system, and a complaint about cracking, rattling, or water ingress usually belongs to the shell.

Body shells and covers on this aircraft are numerous and superficially alike, and a molded plastic panel recovered from a parts bin is not identifiable by appearance. If a shell has arrived without a legible label, compare it against the part you removed feature by feature: the fastener boss pattern, the seam profile, any cable pass through, and the way it presents to the mating half. Anything that differs is a reason to stop and ask rather than to fit it and find out.

If your aircraft carries more than one lance, do not assume the shells are common between positions. Work from the part you removed and from the position callout on the official parts breakdown, and check the boss pattern and any pass through against the new shell before it goes on. Position specific molded parts fit almost correctly in the wrong place, which is precisely why they cause trouble that does not show up until the assembly is closed.

Finally, separate a shell fault from a plumbing fault before you spend anything. If the complaint is leaking, the shell is a suspect only after the fittings, clamps, hose, and the spray hardware inside it have been inspected under pressure with clean water. If the complaint is noise or vibration, check the lance mounting hardware before the cover. The shell earns the order when it is cracked, distorted, whitened at its bosses, or no longer able to be clamped down.

💡 Why This Part Matters

Every acre the T100 covers depends on the mist spray lance doing its job — and the mist spray lance 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 spray lance bottom shell 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 atomized spray system was engineered around — DJI material number YC.JG.ZS006807. No adaptation, no surprises, no second teardown to undo a near-fit part.

This component delivers:

• Factory-correct fit in the mist spray lance — 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 spray lance bottom shell, 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
• Coverage quality the customer can see in the field
• 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 spray lance bottom shell in the USA with free, fast shipping — so the day you need one is the day it ships, not the week you wait.

While the assembly is open, inspect the mating top shell as carefully as the one you are replacing. Both halves took the same impact and both have been carrying the same clamp loads, so a bottom shell that cracked at a boss is a fair warning about the condition of the boss directly opposite it. Look at every fastener location on both halves, and at the flange all the way around, since a nick or a distortion on either side gives you a gap once the assembly is closed.

Check everything the shell was protecting. Any hose inside a lance lives in heat, vibration, and chemical, and it should be pliable rather than hard, swollen, or sticky. Look at every clamp and fitting for a witness mark where it has been rubbing on structure, and check connector shells for moisture and for the green or white deposits that mean spray solution has been sitting in them. Those are the faults that a leaking cover creates, and they will outlive the leak.

If the shell was cracked by an impact rather than by age, widen the inspection before the aircraft flies. Look at the lance mounting hardware and the structure it attaches to, at the propellers and the motor at that position, and at any cable run that passes nearby. A blow hard enough to crack a cover was distributed through everything around it, and the cover is simply the part that showed the damage first because it is the outermost thing there.

What ends the life of a part like this most often is not one big hit, it is sunlight and chemistry working on the material for seasons. Polymer covers lose flexibility as they age, and an aged shell fails from an impact or a vibration cycle that a new one would have absorbed. The visible warning is a surface that has gone chalky and dull, and the structural warning is whitening appearing at more than one fastener boss with no impact mark to explain it.

Clean it with water and a mild detergent and keep everything aggressive away from it. Solvents, chlorinated cleaners, ammonia based products, and strong degreasers attack many polymers, and the damage often shows up a week later as crazing rather than immediately as a stain. No chemical resistance data is published for this shell, so the safe assumption is the conservative one. Rinse the lance out at the end of a spray day so residue never gets the chance to sit against it overnight.

Keep a pressure lance away from the seam and the bosses. A jet aimed at a clamshell joint drives water straight past a seal that was designed to shed mist and rain, not to resist a directed stream, and water inside the shell reaches wiring and connectors that have no protection of their own. Rinse at low pressure, work residue loose with a brush, and let the assembly drain and dry rather than closing the aircraft up wet.

Do not repair a cracked shell and put it back. Adhesive and epoxy on a part that flexes in rotor airflow and gets clamped at multiple points fails at the repair line, usually after enough time has passed that everyone has stopped watching it. A patched shell also traps chemical residue in the crack where nothing can flush it out, and it no longer holds the assembly to the shape the rest of the hardware is mounted against. The same applies to drilling it for anything.

Cold weather deserves respect with molded parts. Polymers get more brittle as temperature falls, so a shell that took a knock in July without complaint can crack from the same handling on a frosty spring morning. Give the aircraft time to warm up before folding, mounting, or working on the lance in the cold, and inspect covers for new cracks after the first cold jobs of the year rather than assuming winter storage was uneventful.

Store and handle the replacement properly. Keep it in its packaging until the old one is out and the area is clean, never stack anything on a lance or lean weight against it in a trailer, and be careful of the fastener bosses and the seam flange when setting it down, since those are the two features that decide whether the assembly closes correctly. A shell that arrives perfect and gets its flange bruised on a bench starts life with the fault you were trying to fix.

Which DJI Agras models does this component fit? Supplier-listed fitment is DJI Agras T100. 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 spray lance bottom shell 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.ZS006807 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 mist spray lance, document connections and hardware positions, swap the spray lance bottom shell 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.

What other parts should I inspect at the same time? On the official diagram this part sits alongside Mist Sprinkler Support Rod, Mist Spray Lance Connector, Centrifugal Sprinkler Adapter Cable (Optional). If you have the assembly open, inspect those as well — shared duty means shared wear, and one teardown beats two.

Water is dripping from under the lance. Does that mean the shell is cracked?

Usually not. The shell is an enclosure, not a pressure part, so fluid that gets loose inside it collects and drains from the lowest opening. That is why the drip shows up somewhere other than where the leak is. Open the assembly, dry everything, refill with clean water, and pressurize on the ground while you watch the fittings, clamps, and hose inside. Order the shell when it is cracked or distorted, not because it was wet.

Can I seal a hairline crack with epoxy to finish the season?

It will not last and it makes the next repair worse. This part flexes in rotor airflow and is clamped at multiple points, so a rigid repair line becomes the new stress concentration and the crack continues past it. A patched crack also traps chemical residue where nothing can flush it, and the shell no longer holds the shape the hardware inside it mounts against. Replace it and keep the old one as a fitting reference if you like.

One of the fasteners spins and will not tighten. What do I do?

That boss has lost its insert or its thread, and the shell can no longer be clamped there. Press the shell down against the fastener to add friction and ease it out rather than driving harder, which only chews what is left. A cover held down at every point but one will chatter at that corner in the airflow and crack from it. Note which boss failed and check the same location on the replacement when it goes on.

Is the bottom shell the same part as the top shell?

No. They are separate components with separate DJI material numbers, and this listing supplies the bottom shell, YC.JG.ZS006807. They sit next to each other on the parts breakdown and look like halves of the same object because they are, which is exactly why they get ordered wrong. Find the label on the half you removed and match the number rather than deciding from the photograph or from which way up it was fitted.

Can a damaged shell actually change my spray results?

It can, indirectly. The shell is part of the structure carrying atomized spray hardware into the airflow beneath the rotors, so a cover that is cracked, loose at a boss, or distorted lets that hardware sit slightly differently and vibrate in place. That is not the first thing to check for a pattern complaint, and pump, flow, and the spray hardware itself come first, but it is worth checking when everything upstream tests clean.

Can I pressure wash the lance at the end of the day?

Rinse it, but keep the lance away from the seam and the fastener bosses. A directed jet drives water past a joint that was designed to shed mist and rain rather than resist a stream, and once water is inside the shell it reaches wiring and connectors that have nothing protecting them. Low pressure, a brush for the stubborn deposits, and enough time to drain and dry before the aircraft gets closed up will do more good than pressure ever does.

What cleaners are safe to use on it?

Water and a mild detergent. No polymer type or chemical resistance data is published for this shell, so the conservative assumption is the correct one. Solvents, chlorinated cleaners, ammonia based products, and strong degreasers attack many plastics, and the damage often shows up a week later as fine crazing rather than immediately as a mark. If a cleaner is aggressive enough to work without effort, keep it away from covers.

Do I need to calibrate or configure anything after fitting a new shell?

Follow whatever the DJI service documentation specifies for your airframe after work on the spray system rather than assuming. What matters regardless is the mechanical verification: nothing pinched in the seam, the seam closed evenly all the way around, all fasteners at proper clamp, and every connector fully latched. Then pressurize with clean water on the ground, run the atomizers, confirm no spray system errors, and inspect for leaks before the aircraft carries chemical.

The shell has gone chalky and faded but has no cracks. Should I replace it?

Treat it as a part on notice. Chalking is the visible end of an aging process that also takes flexibility out of the material, and an aged shell cracks from an impact or a vibration cycle that a newer one would have absorbed. If it is still clamping properly at every boss with no whitening around them, it can stay for now. If whitening is appearing at more than one boss with no impact to explain it, change it before the season rather than during.
