Replacing Flywheel Washers
Replace worn flywheel washers as follows:
1. See Figure 3-70. The washer (10) is a close fit in flywheel
recess and is secured originally by punching flywheel
metal tight against the washer at several points. It is usu-
ally necessary to drill a small hole (1/8 in. (3.2 mm) or
smaller) at the outer edge of the washer to permit prying
with a pointed tool.
NOTE
Drill hole only slightly deeper than thickness of washer. Avoid
removing more material than necessary.
2. Before installing a
new
washer, scrape outer edge of
recess, where metal was punched against original
washer, so
new
washer will seat fully against recess bot-
tom. If washer does not seat fully, forked rod will not have
necessary clearance (side play).

CAUTION
Be sure stepped thrust washers are installed with step
facing crank pin bearing.
Improper installation will dam-
age washer and bearing set and cause accelerated wear
and increased noise.
3. Carefully tap
new
washers into place and using a punch,
peen metal over edge to retain washer.
