Axle shaft needle bearing 917/50200 JCB 3CX/4CX, aftermarket, option 4

Axle shaft needle bearing 917/50200 is an aftermarket part for the JCB 3CX and 4CX backhoe loaders. This bearing is the needle roller bearing of the axle shaft.

A bearing's load capacity and dimensional accuracy are defined by its standard designation (for example the cone and cup numbers of taper roller bearings), which helps confirm that it suits its position in the axle. Bearings are stored dry, clean and lying flat. A bearing with rust marks, dents or cage damage is never fitted.

Compatibility

According to sources, 917/50200 is an NK45/30 needle roller bearing (45 x 55 x 30 mm), used in the axle shafts of JCB 3CX and 4CX backhoe loaders and included in front axle shaft repair kits.

Fitting

When the old bearing is removed, check the housing and shaft seat for burrs, rust and wear, since a worn seat lets the new bearing spin. Renew the seals and O-rings next to the bearing too. When the axle oil is drained, look at the metal particles in it: a lot of particles suggests the gears may also be worn.
