Inspection
1. Thoroughly clean all metal components, except
bearing cones, in a suitable solvent. Dry with
compressed air and coat all threaded components
with light oil to facilitate assembly.
2. Using a suitable solvent, clean bearings and wipe
dry with a lint free cloth. Lubricate lightly with light oil
and spin by hand, to check for wear and roughness.
Replace with new bearings if excessively worn, or if
operation is rough or noisy.
3. Inspect all machined surfaces of all parts for
scoring, pitting, corrosion and burring. Resurface or
replace with new parts as necessary.
4. Inspect all threaded components, and repair or
replace as necessary.

WARNINGS
To prevent personal injury and property
damage, be sure wheel blocks, blocking
materials and lifting equipment are properly
secured and of sufficient capacity to do the
job safely.
Be sure to use a soft drift and take care
when driving in bearing cups with a drift, to
avoid personal injury from chips or fragments.
1. If removed, heat bushing (14) to 177 - 205° C
(350 - 400 o F) in oil to expand it for installation. If oil
heating equipment is not available, heat the bushing
evenly to 205° C (400° F). This takes about 1 minute,
using a torch with a heating tip. Use a Tempilstik or
other temperature gauge to make sure the bushing is
