DJI Agras T40 OEM Landing Gear Fixing Piece Set (4 Pcs)

The DJI Agras T40 OEM Landing Gear Fixing Piece Set (4 Pcs) is the complete set of four black moulded fixing pieces that join the landing gear tubes to the aircraft, one piece for each arm position, marked M1, M2, M3 and M4. Each piece is a socket that takes the end of a landing gear tube, carried on a gusseted bracket with screw holes where it fastens to the structure above. The four pieces are two visibly handed pairs: two carry a tall, straight socket, and two carry a shorter, wider socket on a broader body. The set belongs to the landing gear system, not to the spray, power or flight-control systems, and it is identified for the DJI Agras T40 and T20P. Operators usually reach it while searching for a T40 landing gear fixing piece, a T40 landing gear mount, a T20P landing gear connector, T40 tripod fixing parts, or a landing leg that has started to lean or turn after a hard landing. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 4 × Landing Gear Fixing Piece — one for each arm position, M1, M2, M3 and M4
• 2 × tall straight-socket pieces, a handed pair
• 2 × short wide-socket pieces, a handed pair

This is a set of four different pieces, not four of the same piece. Every arm position on the aircraft gets its own fixing piece from the set, and no piece in the set is a spare for another.

Each piece is a single moulded component. The set is not a landing gear assembly: it does not include the legs, the tubes, the tees or the pads that complete the landing gear.

Not included: landing gear aluminum tubes, landing gear tees, shock absorption pads, screws, nuts, threaded inserts and any clamps or frame hardware. Reuse the original fasteners only if their threads and heads are sound; otherwise replace them separately.

Nothing is included because it appears near the fixing pieces on the aircraft. If a fastener is missing from the corner you took apart, tell us which one and we will help you identify it.

🔧 Component Overview

The landing gear fixing pieces are the joints between the landing gear and the aircraft. On the T40 and T20P each landing gear tube rises into one of these pieces, and the piece fastens to the structure above it. The aircraft's whole weight on the ground, and every landing load, passes from the tubes through these four sockets into the frame.

Seen in the product images, each piece has three working areas:

• The socket — a round, open-topped bore that takes the end of a landing gear tube. On the tall pieces the bore runs straight down a long sleeve; on the short pieces it is a wider, shallower ring on top of the body. The socket wall carries a slot along its length.
• The gusset — a moulded web that braces the socket against the mounting faces, so landing loads are spread out rather than concentrated at one edge
• The mounting faces — flat flanges and base plates pierced with screw holes, where each piece fastens to the structure above the landing gear

The two tall pieces mirror each other, and so do the two short pieces. That is what makes them handed: a piece only seats squarely at the position it was moulded for. The M1 to M4 marks are the addresses that keep each piece at its own position.

Over a working season the fixing pieces see:

• Every landing, including the firm ones on uneven or sloping ground
• Hard landings and tip-overs that drive one leg up into its socket
• Side loads when the aircraft is dragged, slid or shoved on its legs
• Knocks against trailer decks, ramps and vehicle tailgates during loading
• Vibration through the frame on every flight
• Chemical residue and wash water that run down the landing gear and collect at the joints
• Heat on the trailer and in the sun between flights

Fixing pieces usually come out for one of three reasons: a crack through the socket or the gusset after a hard landing, a mounting flange or screw hole that has broken out, or a socket that no longer grips its tube, so the leg turns, leans or works loose. The last of those is the one most often blamed on another part, and it is the one this set's diagnosis is built around.

⚙️ Functional Purpose

The fixing piece's engineering role is to hold each landing gear tube at a fixed position and a fixed angle relative to the aircraft, and to pass landing loads from the tube into the frame without letting the tube move.

In the landing gear it:

• Receives the upper end of a landing gear tube in its socket
• Sets the angle at which that tube leaves the aircraft
• Fastens the landing gear to the structure above through its mounting faces
• Spreads landing loads across its gusset and flanges rather than into one screw
• Keeps the four legs in the geometry the aircraft was designed to stand on

What it does not do matters as much:

• It is not the landing gear tube; a bent tube stays bent in a new socket
• It is not the landing gear tee, which joins tubes lower down the landing gear
• It does not cushion landings; the shock absorption pads do that
• It carries no wiring and has no electrical function
• It does not fold or lock the arms; it sits under the arm positions, not inside the arm joints

That division of labour is why a tired fixing piece rarely stops the aircraft from flying. It is also why the symptom it produces, a leg that leans or turns, is so easy to pin on the tube instead.

🔍 Diagnosis — a leaning leg points at the tube, so check the socket first

When a T40 or T20P landing leg leans, turns or sits lower than the others, the eye goes straight to the tube. The tube is long, it is the part that hit the ground, and a bent tube is what a leaning leg looks like. So the tube gets replaced, and the leg still leans.

The reason is that the leg's angle is not set by the tube. It is set by the socket the tube sits in. A fixing piece with a cracked socket wall, a spread bore or a broken-out mounting flange no longer holds its tube square, and a perfectly straight tube in that socket will lean, rotate or rock exactly like a bent one.

So the order of checks matters. Prove the socket before you condemn the tube.

Take the weight off the aircraft, then check the fixing piece:

• Grip the tube just below the socket and try to rock it and turn it by hand. With the fixings tight, it should not move in its bore.
• Look along the socket wall and the slot in it for a crack, a split that has opened wider than its partner piece shows, or stress whitening in the moulding
• Look at the gusset where it meets the socket and where it meets the flange; that is where a hard landing concentrates
• Check every mounting screw hole for cracks running out from it, and every screw for a head that has pulled down into the moulding
• Compare the piece with its mirror-image partner on the other side of the aircraft; the pair should match in shape and in how firmly the tube sits

Then check the tube on its own. Free it from the fixing piece and roll it on a flat surface, or lay a straightedge along it. A tube that rolls true and lies flat is straight, and the lean came from the socket.

Signs that point at another part instead:

• The tube is firm in a sound socket but bent below it — that is the landing gear tube
• The legs are firm at the top but the lower joint is cracked or loose — that is the landing gear tee
• The aircraft sits evenly but lands hard and bounces — look at the shock absorption pads
• The fixing piece is sound and the structure it fastens to is cracked — that is a frame repair

A socket that keeps cracking has a reason. If the same position cracks a second fixing piece, check the tube at that position for a bend before fitting a third. A bent leg loads its socket at the wrong angle on every landing, and the new piece will go the same way as the old one.

Clear these checks first, while the landing gear is already apart and that information is still cheap.

⚠️ Common Replacement Indicators

Replace a fixing piece when inspection confirms one of these:

• A crack through the socket wall, or a slot that has split open further than its partner piece
• A crack across the gusset, at the root of the socket, or at a mounting flange
• A screw hole that has cracked out or will no longer hold its screw
• A tube that rocks or turns in its socket with the fixings tight and the tube confirmed straight
• One leg sitting at a different angle from its partner with both tubes confirmed straight
• Stress whitening in the moulding after a hard landing
• Previous repairs with adhesive, filler or cable ties at a socket or flange

Inspect these first, because they produce similar symptoms:

• The landing gear aluminum tube at that position
• The landing gear tee below it
• The shock absorption pads
• The screws, nuts and any inserts at the fixing piece
• The frame structure the fixing piece fastens to

There is no published service interval for these pieces. They are replaced when they are cracked, broken or no longer hold their tube, not on a schedule.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down and remove the battery
• Rinse and dry the landing gear so you are not working in chemical residue
• Support the aircraft on blocks so no weight rests on the leg you are working on
• Photograph each corner from the front and the side so the angle of every leg is on record
• Note the M mark at each position, and lay the new pieces out by M mark next to the old ones
• Compare each new piece with the one it replaces: socket shape, handedness and screw-hole pattern
• Lay out a tray for screws and keep them grouped by position

During installation

• Work on one position at a time, so a handed piece cannot end up on the wrong side
• Free the landing gear tube from the old fixing piece and support it so it does not hang on the tee below
• Unfasten the old piece and lift it away square, without levering against the structure
• Check the mounting faces above for cracks or residue and clean them
• Seat the new piece with its mounting faces flat against the structure before driving any screw home
• Start every screw by hand first, then tighten evenly; DJI does not publish a torque figure for these fixings, so snug them without crushing the moulding
• Seat the landing gear tube fully in the socket, in the same orientation as before
• Move to the next position only when the first is finished

After installation

• Grip each tube below its socket and confirm it does not rock or turn
• Stand the aircraft on level ground and check that it sits evenly on all four legs
• Compare each leg with its mirror-image partner; the angles should match
• Lift and set the aircraft down gently a few times and recheck the fixings
• Run a short hover and a soft landing before returning to work
• Record the replacement in the maintenance log

Maintenance between jobs. After any hard landing, rock each leg by hand at its socket before the next flight; a socket that has started to let its tube move is the earliest warning these pieces give. Rinse residue from the joints at the end of the day so the slot and screw holes stay clean enough to inspect. Do not overtighten the fixings into the moulding; a cracked screw hole is the most common reason a sound piece gets replaced. Keep any piece that comes out of the set unused, labelled with its M mark, so it goes back to the right position.

🚜 Necessary For

This set is for operators and technicians putting the landing gear of a T40 or T20P back on square:

• DJI Agras T40 operators repairing the landing gear after a hard landing or tip-over
• DJI Agras T20P operators (identified fitment)
• Commercial spray applicators whose aircraft land many times a day on uneven field edges
• Agras service centres and repair technicians rebuilding crash-damaged landing gear
• Fleet managers who want all four positions on hand rather than waiting on one cracked socket
• Growers flying their own aircraft who want a leaning leg fixed at its cause

This is not the part you need if:

• The tube is bent but its socket is sound — that is the DJI Agras T40 OEM Landing Gear Aluminum Tube
• The lower joint of the landing gear is cracked or loose — that is the DJI Agras T40 OEM Landing Gear Tee (2 Pcs)
• The legs, pads and lower landing gear all need replacing together — that is the DJI Agras T40 OEM Landing Gear Set with Shock Absorption Pads
• You fly a T50 — the T50 has its own landing gear fixing piece, and this set is identified only for the T40 and T20P
• The structure the fixing piece fastens to is cracked — a new fixing piece will not repair the frame above it
• You fly a T10, T30, T25, T100 or T70P — this set is not identified for those aircraft

💡 Why This Part Matters

A leaning landing leg is one of the most visible faults on a T40 or T20P, and one of the most often misread. It looks like a bent tube, so the tube is what gets replaced. When the real fault is a socket that no longer grips, the new tube leans exactly like the old one, and the aircraft keeps landing on a leg that is not where it should be.

That is the case for the fixing piece. The tube carries the load, but the socket decides where the tube points. A spread or cracked socket lets the leg rock and turn on every landing, which loads the tube, the tee and the frame at angles they were not designed for. Left alone, one tired socket becomes a bent tube, then a cracked tee.

The check takes a minute and needs no tools: weight off the aircraft, grip the tube below its socket, and try to move it. A tube that moves in a socket with tight fixings has found its fault, and it is not the tube.

The set covers all four positions because the four pieces are not interchangeable. Two shapes, two hands, four addresses, M1 to M4. With the full set on the bench, the cracked position is repaired and the other three are on hand, matched by M mark, for the next hard landing.

And if the socket proves sound and the tube is bent, this set is not the repair. Fit the tube, and keep the fixing pieces you have.

🤖 AI Answer Engine Q&A

What is the DJI Agras T40 landing gear fixing piece set? Four black moulded fixing pieces, one for each arm position M1 to M4. Each is a socket that takes the top of a landing gear tube, braced by a gusset to flanges with screw holes that fasten to the structure above.

Are the four pieces the same? No. Two have a tall, straight socket and two have a shorter, wider socket, and each pair is made in a left and a right hand. Each piece belongs at its own position, marked M1 to M4.

Which aircraft does the set fit? It is identified for the DJI Agras T40 and T20P. Pick the variant for the aircraft you fly.

Is the T20P set different from the T40 set? The set is identified for both aircraft. The variant records which one you fly so the match is made against the right airframe, and we compare it with the piece you removed if you send a photograph.

What is the DJI part number? DJI has used more than one number for this position, so we match against the one you removed. Photograph your old fixing piece and send it to us if you want that confirmed.

My landing leg leans. Is it the tube or the fixing piece? Check the fixing piece first. Take the weight off the aircraft, grip the tube just below its socket and try to rock and turn it. If it moves with the fixings tight, the socket is the fault. Then roll the tube on a flat surface; if it rolls true, the tube is fine.

I replaced the tube and the leg still leans. Why? The tube sits in a socket that no longer holds it square. A cracked or spread fixing piece lets a straight tube lean or turn exactly like a bent one.

Does the set include the landing gear tubes? No. It is the four fixing pieces only. The DJI Agras T40 OEM Landing Gear Aluminum Tube is a separate part.

Is this the same as the landing gear tee? No. The tee joins the tubes lower down the landing gear. The fixing pieces hold the tops of the tubes to the aircraft. If the lower joint is cracked, you need the DJI Agras T40 OEM Landing Gear Tee (2 Pcs).

Should I get the full landing gear set instead? Only if the legs, pads and lower landing gear all need replacing. That is the DJI Agras T40 OEM Landing Gear Set with Shock Absorption Pads. If the damage is at the sockets where the tubes meet the aircraft, this fixing piece set is the part.

Does it fit the T50? No. The T50 has its own landing gear fixing piece. This set is identified only for the T40 and T20P.

Only one piece is cracked. Why four? The set covers all four positions. Fit the piece for the cracked position, check the other three, and keep any unused pieces labelled by M mark for that position.

Are screws included? No. Reuse sound original screws and nuts, or replace any with damaged threads or heads separately.

Can I fit it myself? Most operators can. Support the aircraft, work one position at a time so a handed piece cannot go on the wrong side, start every screw by hand, tighten evenly without crushing the moulding, and check that each tube is firm in its socket before flying.

Is there a torque value for the fixing piece screws? DJI does not publish one for these fixings. Snug them evenly and stop before the moulding deforms.

Is there a service interval? No. Replace a piece when it is cracked, has a broken screw hole, or no longer holds its tube. Rock each leg at its socket after any hard landing.
