Hub cassette seal 154055 Carraro, aftermarket

Hub cassette seal 154055 is an aftermarket part for the backhoe loaders with Carraro axles.

The hub seal seals the rotating joint between the planetary gearbox and the hub at the axle end. A cassette seal has its own running surface, so shaft wear affects its life less. When the seal leaks, the planetary oil level drops, oil reaches the brake discs or the wheel side, and dust and water get in and ruin the bearings.

Specifications

Fitting

For the change, remove the wheel and planetary gearbox and drain the oil. Clean the bore, lubricate the seal's outer surface and fit it the right way round. After assembly, fill the planetary with the specified oil and check for leaks after the first run. Take care that the seal does not tilt as it goes into the bore, since a cocked lip presses unevenly on the shaft and soon leaks.
