Axle shaft 914/84501 JCB 3CX/4CX, aftermarket

For the JCB 3CX and 4CX backhoe loaders: axle shaft 914/84501, an aftermarket part.

The axle shaft is chosen by part number according to its length, spline count and end form, and shafts may differ between front and rear axles and between left and right. When replacing it, check the gears its splines engage and the bearings, since a worn splined hub soon ruins a new shaft too.

Fitting

For the change, remove the wheel and planetary gearbox and drain the axle oil. Slide the new shaft carefully into place with its splines lubricated with clean axle oil, using a protective sleeve so the splines do not damage the seal lips. Renew the seals and O-rings and top up the axle oil to level. The shaft comes new; check its splines and bearing surfaces before fitting. Also inspect the other shaft in the axle and the universal joint for wear. When the axle shaft is changed, check the splines of the differential side gear and the planetary sun gear too. Shafts on the two sides of an axle may differ in length, so lay the new one beside the old one to compare. Change the axle oil and inspect the metal on the drain plug.
