For the JCB 3CX and 4CX backhoe loaders: differential friction disc 450/20402, an aftermarket part. This part is a friction disc of the limited-slip differential (LSD).

In limited-slip differentials (LSD) the friction discs help pass torque to the wheel with grip when the other wheel spins, improving traction in mud and on slippery ground. As the discs wear this effect fades and the machine spins its wheels easily. LSD axles use the additive axle oil the maker recommends, since unsuitable oil makes the discs judder and chatter.

Compatibility

According to sources, 450/20402 is a sintered bronze LSD friction disc with 28 teeth, 88 x 57.3 x 2.1 mm, used in JCB 3CX, 4CX and Loadall axles. The catalogue also has the genuine version of this part. Other parts are in Reduction gears.

Fitting

The differential is changed with the axle opened; because it affects the crown wheel and pinion setting, the work is done with measurements to the service manual. Set the differential bearing preload and the crown wheel backlash, check the contact pattern and torque and lock the crown wheel bolts. Renew the seals and gaskets and fill the axle with the specified oil type and quantity.

JCB 3CX / 4CX Rear Axle Overheating: Causes and What to Check

The rear axle of a JCB 3CX or 4CX backhoe loader runs hotter than the front axle by design: it houses the oil-immersed service brakes, one multi-plate brake pack on each half shaft. A warm axle casing after a shift is therefore normal. It becomes a concern when the axle gets very hot after an ordinary road run, the machine feels as if it is dragging, there is a smell of burnt oil from the axle, or oil starts leaking past the seals. The usual cause is brake drag: the service brakes or the park brake are not releasing fully. Below, based on the JCB service manual, is what to check and in what order.
