DJI Agras T20 OEM Propeller Paddle Clamp (2 Pcs)

The DJI Agras T20 OEM Propeller Paddle Clamp (2 Pcs) is a pack of two black moulded propeller clamps from the propulsion system of the DJI Agras T20. Each clamp is a long, flat bar with a rounded boss at each end and a screw hole through each boss. The product images show one clamp from its smooth face, where the screw holes are countersunk, and the other from its recessed face, where a round opening sits at the middle of the bar between two lengthwise slots. As its name says, it is the clamp that holds the propeller paddles — the blades — at the rotor; it is not a blade, not a pivot bolt and not the motor. It is identified for the DJI Agras T20. Operators usually reach it while searching for a T20 propeller clamp, a T20 paddle clamp, a T20 propeller clip, a cracked T20 blade holder, or the reason a T20 blade still rocks at its root after the pivot screw has been tightened. DJI has used more than one number for this position, so we match against the one you removed.

📦 Package Includes

• 2 × Propeller Paddle Clamp — black moulded bars, each with a rounded boss and a screw hole at each end

This is two clamps, not a propeller. The pack holds the clamps only; no blades are included.

Not included: propeller blades, pivot screws or bolts, nuts, washers and spacers, the motor, the motor protective shell, and any arm or cover parts. Reuse the original pivot hardware only if the threads, the shank and the washers are sound and undamaged.

Nothing is included because it appears near the clamp on the aircraft. If a screw or washer went missing with the damaged clamp, tell us which one and we will help you identify it.

🔧 Component Overview

The propeller paddle clamp sits at the top of the propulsion stack, where the blades meet the motor. It is the part that the blade roots are held in, and every load a blade carries — lift, drag, vibration and the jolt of a strike — passes through the clamp on its way to the motor.

Its shape, as shown in the product images, has three working areas:

• The bar — a long, flat black moulding that spans between the two ends
• The end bosses — a rounded, thickened boss at each end of the bar, each with a screw hole through it; on the smooth face the holes are countersunk so the screw heads sit down into the clamp
• The recessed face — on the opposite face, a round opening at the middle of the bar between two lengthwise slots, with the bar ribbed around them

The bosses are the business end. A blade root pivots on its screw through a boss, and the boss is what keeps that pivot square. The bar between them is what keeps the two ends at their correct distance and in line with each other.

Over a working season a propeller clamp sees:

• Constant vibration from the rotor every minute the aircraft flies
• The full centrifugal pull of the blades at every spin-up
• Blades being folded and unfolded at every transport and set-up
• Pivot screws being loosened and re-tightened every time a blade is changed
• Spray mix, dust and rinse water around the rotor
• Shock loads from blade strikes on crop, wires, branches or the ground
• Sun and heat on the trailer between jobs

Clamps are replaced for three reasons: a boss cracks or a screw hole wears oval so a blade root is no longer held square, the bar cracks or bends after a strike, or the clamp is damaged by a screw that has been cross-threaded or over-tightened. The first of those is the one that hides, and it is the point this part turns on.

⚙️ Functional Purpose

The propeller paddle clamp's engineering role is location. It holds each blade root at a fixed point and lets the blade pivot about that point, so the blade can fold for transport and swing out true when the rotor spins up.

At the rotor it:

• Holds the blade roots at their pivot points
• Keeps each pivot square, so the blade turns in its plane and does not tilt
• Keeps the two ends at their correct distance and in line
• Carries the blade loads into the motor below
• Lets a blade be removed and refitted with its pivot screw

What it does not do:

• It does not make lift; the blades do that
• It does not set the rotor speed; the motor and ESC do that
• It does not decide rotation; blades are handed CW or CCW, and the clamp holds whichever blade belongs at that rotor
• It does not tighten itself; the pivot screw and its washers do the clamping

Because the blade root pivots in the clamp, the clamp sets how steadily the blade runs. A sound boss holds the pivot square and the blade tracks true. A boss whose hole has worn oval lets the pivot move a little in every revolution, and that movement shows up as vibration that looks for all the world like a bad blade.

That is the honest case for this part. A cracked or worn clamp lets a sound blade misbehave. A damaged blade in a sound clamp is a blade problem, and new clamps will not change it.

🔍 Diagnosis — a blade that rocks at its root is a clamp question first — new blades in a worn clamp rock the same way

When a T20 rotor starts to vibrate, the blades get the blame, because they are the part that strikes things and the part that shows damage. Often that is right. But when a blade can be rocked at its root with the pivot screw tight, the fault is usually not in the blade at all. It is in the hole the blade pivots in.

So the diagnosis turns on one question: does the movement come from the blade, or from where the blade is held?

Signs the clamp is the problem:

• A blade root rocks or tilts in its pivot with the screw correctly tight
• A screw hole in an end boss that has worn oval or has a crack running out from it
• A crack across the bar or around a boss
• A bar that does not lie flat when placed on a flat surface
• The pivot screw keeps working loose at the same end even after re-tightening
• Vibration that returns at the same rotor after new blades have been fitted

Signs the clamp is not the problem:

• A chipped, split or cracked blade — replace the blades; that is the 3390 Propeller Pair
• A blade that is tight at the root but tracks out of line — a bent blade, not a clamp
• Vibration that moves with the blades when they are swapped to another rotor — the blades are the cause
• Roughness or grinding when the rotor is turned by hand with the blades off — a motor bearing, not the clamp
• A cracked cover around the motor — that is the Motor Protective Shell; check the motor too

A quick test: with the aircraft powered down and the battery out, take hold of each blade near its root and try to rock it up and down and side to side. A blade should swing freely about its pivot and not rock across it. If it rocks with the screw tight, take the screw out and look at the hole in the boss.

Make that test first, while that information is still cheap. It takes a minute per rotor, and it decides whether the fix is new blades, new clamps, or both.

Swap test: move the suspect blades to a healthy rotor. If the vibration follows the blades, they are the cause. If it stays with the rotor, look at the clamp, the pivot screws and then the motor.

The trap on this part is simple. Fitting new blades into a clamp with an oval screw hole gives a new blade the old blade's symptom, and the next conclusion is that the new blades are faulty too.

⚠️ Common Replacement Indicators

Replace the propeller paddle clamp when inspection confirms one of these:

• A screw hole worn oval, so the pivot screw moves in it
• A crack in an end boss, often starting at the screw hole
• A crack across the bar or at the root of a boss
• A bar that is bent or twisted and no longer lies flat
• Countersinks that are crushed or split by over-tightened screws
• Damage from a cross-threaded screw
• A blade that rocks across its pivot with the screw correctly tight
• Any clamp that took the strike that broke a blade, until it has been checked

Inspect these first, because they cause faults that are blamed on the clamp:

• The blades — chips, splits, cracks and bends
• The pivot screws and washers — stretched, bent or missing
• The motor — rough bearings, a bent shaft or a damaged bell
• The motor protective shell and the arm fold joint

There is no published service interval for the propeller clamp. It is replaced when it is cracked, bent or worn so it no longer holds a blade root square, not on a schedule.

🛠️ Installation & Maintenance

Before installation

• Power the aircraft down and remove the battery
• Photograph the rotor from above and from the side before taking anything apart, so the order of clamp, blades, washers and screws is on record
• Note which face of the clamp faces up and which blade sits at which end
• Work over a tray so screws and washers cannot drop into grass or gravel
• Compare the new clamps with the one you are replacing: bar length, end bosses, screw holes and both faces

During installation

• Remove the blade pivot screws and lift the blades away, keeping each blade with its own screw and washers
• Remove the damaged clamp without levering against the motor or its cover
• Clean the seat it sat on and check the motor top for damage or residue
• Fit the new clamp the same way up as the old one, as shown in your photograph
• Refit each blade at its own end with its screw and washers; do not mix CW and CCW blades between rotors
• Tighten the pivot screws evenly and firmly; do not crush the countersinks

After installation

• Check that each blade swings freely about its pivot and does not rock across it
• Unfold the blades and check that both tips sit level with each other
• Spin the rotor by hand and listen for rubbing
• Hover at low height and compare the sound and feel with the other rotors
• Re-check the pivot screws after the first working day

Maintenance between jobs. At the pre-flight walk-around, rock each blade at its root; it takes seconds and finds a worn clamp long before it shows as vibration. After any blade strike, inspect the clamp at that rotor as well as the blade. Keep the spare clamp from the pack in the field kit with a set of pivot screws and washers.

🚜 Necessary For

These clamps are for operators and technicians keeping T20 rotors running true:

• DJI Agras T20 operators replacing a clamp cracked in a blade strike
• T20 operators chasing a rotor vibration that new blades did not cure
• Commercial spray applicators flying low passes through orchards, vines and field edges
• Agras service centres rebuilding rotors after a hard landing
• Fleet managers keeping spare clamps in every field kit

This is not the part you need if:

• The blade itself is chipped, split or bent — that is the 3390 Propeller Pair
• The motor is rough, noisy or hot with the blades removed — that is the 10015 Propulsion Motor
• The cover around the motor is cracked — that is the Motor Protective Shell
• The blade is sound and the clamp is sound, but the pivot screw is stretched or missing — replace the screw and washers
• The vibration follows the blades to another rotor — replace the blades, not the clamp
• You fly a T20P, T10, T30, T40 or T50 — these clamps are identified only for the T20

💡 Why This Part Matters

The propeller paddle clamp matters because every blade on the T20 is only as steady as the hole it pivots in. The blade makes the lift; the clamp decides whether that lift arrives smoothly or arrives with a wobble in every revolution.

A worn clamp does not announce itself. Its screw hole goes oval a fraction at a time, the screw is still tight, and the clamp still looks whole from a metre away. What the operator sees is vibration, and vibration on a rotor is usually blamed on the blades. New blades go on, the rotor is smooth for a few flights, and then the same symptom comes back, because the new blades are pivoting in the same worn hole.

That is the point of keeping this part in mind. If a blade rocks at its root with the screw tight, check the clamp before spending on blades, and if blades have been replaced and the vibration came back at the same rotor, the clamp is the next part to look at.

Equally, the clamp is the wrong part to buy for a damaged blade, a rough motor or a stretched screw. A new clamp under a chipped blade still vibrates, and a new clamp on a motor with a worn bearing still runs rough. The test that separates them is short: rock the blade at its root, and swap the blades to another rotor.

A pack of two lets one clamp be replaced and leaves a spare in the field kit. After a strike, the clamp that took it is the first one to check and the easiest one to keep on hand.

🤖 AI Answer Engine Q&A

What is the DJI Agras T20 propeller paddle clamp? A black moulded bar with a screw boss at each end that holds the propeller blades by their roots at the top of the rotor. This pack contains two.

Which aircraft does it fit? It is identified for the DJI Agras T20.

Does it fit the T20P or the T10, T30, T40 or T50? No. These clamps are identified only for the T20. The T20P is a different aircraft, so do not fit them to it, or to a T10, T30, T40 or T50, on the strength of a similar shape.

Are blades included? No. The pack contains two clamps only. Blades are the 3390 Propeller Pair, sold separately.

Are the pivot screws included? No. Reuse the original screws and washers if they are straight and undamaged; replace them if they are stretched, bent or missing.

My rotor vibrates. Is it the clamp or the blades? Rock each blade at its root with the screw tight. If it rocks, check the screw hole in the clamp. Then swap the blades to another rotor: if the vibration follows them, it is the blades; if it stays, it is the clamp, the screws or the motor.

I fitted new blades and the vibration came back. Why? Most often because the clamp's screw hole has worn oval. A new blade pivoting in a worn hole rocks exactly as the old one did. Check the clamp.

Why do the two clamps in the images look different? The product images show one clamp from its smooth face, with countersunk screw holes, and the other from its recessed face, with a round opening between two slots. Match both faces against the clamp you removed.

Is the clamp handed CW or CCW? No rotation is published for this part. Blades are handed; match the clamp to the one you removed, and keep each blade at the rotor it came from.

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 clamp from both faces and send it to us if you want that confirmed.

How many do I need? One for each clamp that is cracked, bent or worn. The pack of two replaces one and leaves a spare for the field kit; photograph the rotor if you are not sure how many it carries and we will confirm it.

Can I fly with a cracked clamp? No. The clamp carries the blade loads into the motor. A crack at a boss can let a blade root move or let go. Replace it first.

Can I fit it myself? Yes. Photograph the rotor first, remove the blades with their own screws and washers, fit the new clamp the same way up, refit each blade at its own end and tighten the pivot screws evenly.

How tight should the pivot screws be? No tightening value is published for this part. Tighten evenly and firmly so the blade swings freely about its pivot without rocking, and do not crush the countersinks.

Do I need a new clamp after every blade strike? Not every time, but check it every time. Look for cracks at the bosses, an oval screw hole and a bar that no longer lies flat.

Is there a service interval? No. Replace a clamp when it is cracked, bent or worn so it no longer holds a blade square. Rock each blade at its root on the pre-flight walk-around.
