A high-quality 453/04402 planet carrier (also referred to as "Annulus Carrier Splined") by GX-AFTER. This is a key component of the planetary gear set (final drive) in JCB axles. This carrier holds the planet gears and splines into the wheel hub, transferring the reduced torque to the wheel. It fits 2CX, 3CX, 4CX backhoe loaders and telehandlers, among others.
GX-AFTER is the smart choice for your machine. We provide high-class replacements that combine excellent quality with an attractive price. Each part is carefully verified to ensure full compatibility and reliability you can depend on.

| JCB | Telehandlers |
The list above is for reference. It is crucial to verify the part number 453/04402 in your axle's parts catalogue.
The 453/04402 carrier works directly with the planet gears, planet pins, bearings, and the sun gear. When replacing, we recommend inspecting all other gear components and changing the axle oil.
Failure (cracking or stripped splines) of the planet carrier will lead to an immediate loss of drive to that wheel. This can cause the machine to "pull" violently to one side while driving. Metal fragments from the failure will contaminate the axle oil, leading to the destruction of bearings and other gears.
The 453/04402 planet carrier (Annulus Carrier) is the "heart" of the planetary gearset. It is the component that holds the planet gear pins. The sun gear (from the axle shaft) drives the planet gears, which orbit inside the ring gear (annulus), and the rotating planets force the entire carrier to rotate. This carrier is splined to the hub, transferring the final, reduced torque to the wheel.

No. The "Sun Gear" is the central gear. The "Annulus" is the outer ring gear. The "Annulus Carrier" (or Planet Carrier) is the housing that holds the planet gears, which rotate between the sun gear and the annulus. This part (453/04402) is that splined carrier/housing.
It is very likely. A loss of drive in one wheel is most often caused by a failure in the final drive. This could be a failed sun gear, a cracked planet carrier (this product), or a broken axle shaft. Disassembly is required to verify.
