Axle bearing 642513 Carraro, aftermarket

Axle bearing 642513 is an aftermarket part for the backhoe loaders with Carraro axles.

In construction machine axles the bearings support the gears and shafts and carry both radial and axial loads. On backhoe loaders and telehandlers the axle works hard, with bucket loads, shocks from rough ground and frequent changes of direction, and the bearings must carry these loads without upsetting the gear mesh. A worn bearing changes the gear clearances, causes whine and heat and in time damages the gears and seals, so it is replaced at the first signs of wear.

Specifications

Compatibility

According to the product card, Carraro 642513 is a bearing; cross numbers: CA0642513, 302-5841, 87708444. Fit is confirmed by the axle or transmission type. Other parts are in Carraro.

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. The bearing is chosen by comparing its number and dimensions (bore, outside diameter and width) with the old one. During the first hours of work after the change, feel the axle casing around the bearing: excessive heat indicates too much preload, and the adjustment must be redone.
