Oil or scratches on the inner surface of the
brake drum will impair braking performance
or result in abnormal noises. Remove oil by
wiping the brake drum with a rag soaked in
lacquer thinner or solvent. Remove scratches
by lightly and evenly polishing the brake drum
with emery cloth.
Brake shoe plate
Remove the camshaft, and grease it. If the
cam face is worn, replace the camshaft.
NOTE: ______________________ __
Before removing the cam lever, put align-
ment marks on the cam lever and camshaft to
indicate their relative positions for easy
assembly.
Replacing the wheel bearings
If the bearings allow play in the wheel hub or
if the wheel does not turn smoothly, replace
the bearings as follows:
1. Clean the outside of the wheel hub.
2..
Drive the bearing out by pushing the
spacer aside and tapping around the
perimeter of the bearing inner race with
a soft metal drift punch and hammer.
The spacer "floats" between the bear-
ings. Both bearings can be removed in
this manner.
WARNING:
Eye protection is recorn mended when
using striking tools.
3. To install the wheel bearing, reverse the
above sequence. Use a socket that mat-
ches the outside diameter of the race of
the bearing to drive in the bearing.
Do not strike the center race or balls of
the bearing. Contact should be made on-
ly with the outer race.
