Mark disassembled wheel hubs and bearings
to prevent mixing up during re-assembly! The
inner races of the bearings with rollers must be
placed on the same hub again during assembly!

removed. Clean seals and bearings also
thoroughly and check if they can be reused.

10. Fill grease between the tapered rollers and
cage of the bearing until the rollers are com-
pletely covered.

clean thoroughly.
12. Fill the cap with long-term grease before
reassembling it.
13. Mount the wheel hub and axle nut again.
14. Adjust the bearing and brake settings.
15. Perform a function check and corresponding
test drive after the adjustment. Correct any
