Prepare Parts for Assembly
Inspect Parts
It is very important to inspect all parts
carefully and completely before the axle
or carrier is assembled. Check all parts
for wear or stress and replace damaged
parts. Replacement of damaged parts
now, will prevent complete failure of the
assembly later.
1. Inspect tapered roller bearings:
Inspect the cup, cone, rollers and
cage of all tapered roller bearings in
the assembly. If any of the following
conditions exist, the bearing MUST
be replaced.
