Inspections and checks
Clean bearings and the other parts carefully, then dry using
compressed air. Carefully examine the bearings turning them
slowly, if the bearing is sound no vibrations, noise nor slight
jam-ups shall be felt.
Carefully examine bearing race and rolling member conditions
ensuring no scoring, marking, grinding signs due to foreign matter
abrasion are noticed, otherwise replace the bearing.
WARNING: Should a bearing be no more serviceable, both the
internal and the external bearings must be replaced.
Make sure the wheel shaft has suffered no damage and threading
is whole, replace if required.
Ascertain clearance hole A permitting the external cover to be
fixed is not obstructed by foreign matters, if so remove any
clogging to allow hub B to be properly lubricated.
Wash any components carefully and dry with compressed air.
Be sure no signs of oxidation are visible on the wheel shaft, if so
remove with very fine abrasive paper.
Check the shaft for either warp or damage, if so replace the shaft.
Carefully inspect the axial bearing making sure no grinding, scor-
ing or marking are evident neither on the rolling members nor on
the bearing races, otherwise replace the worn parts.
Check side axle upper and lower bushes B for wear, ascertaining
they still show evidence of the purpose-made indentations, other-
wise replace.
