NOTE
See Figure 3-68. If it is necessary to remove either the pinion
shaft bearing (11) or sprocket shaft bearing (4 and 9), pro-
ceed as follows:
11. Pinion bearing (11) will remain on pinion shaft. Remove
retaining ring (10), and bearing (11) may be slipped off
pinion shaft.
12. See Figure 3-69. Pull sprocket shaft bearing with

races.
NOTE
See Figure 3-68. Do not remove retaining ring (7); the crank-
case can easily be damaged during the removal process.
Removal of the retaining ring is not necessary for the removal
or installation of the outer bearing races.
Flywheels
1. See Figure 3-70. Place flywheel assembly in holding fix-
ture. Remove crank pin nut (1). Strike left flywheel with
soft metal mallet at about 90° from crank pin hole on
wheel periphery to loosen. Lift left flywheel (2) off crank
pin.
2. Hold down crank pin bearing assembly (4) with a short
length of pipe or tubing so connecting rods (3) may be
slipped off bearings, then remove bearing assembly.
Secure bearings (4) together in set until they are washed
and refitted to crank pin.
3. Remove crank pin nut (9), then tap crank pin (6) out of
flywheel and remove key (7).
CLEANING/INSPECTION
1. Wash all parts in solvent and blow dry with compressed
air. Examine crank pin for wear, grooving and pitting. If
the surface is at all worn, replace with new pin. Examine
flywheel washers. If either washer is worn or grooved, it
should be replaced. See
WASHERS on page 3-51.
2. Examine connecting rod lower races. If they appear
slightly grooved or shouldered where edge of bearing
rollers ride, they may be lapped out, and an oversize
crank pin and new bearing installed. If they appear badly
worn, grooved or pitted, new rods should be installed,
preferably as an assembly with new bearings and crank
pin.
3. Inspect bearing for wear, pitting and heat discoloration.
Replace as required.
4. Inspect crank pin, crank pin roller and connecting rods for
correct freeplay.
