Inspect the crankshaft bearing area for wear. If any wear
is noted on either end, replace the crankshaft end.
NOTE: Install the bearings by sliding each bearing
onto the crankshaft making sure the retaining pin
hole (A) in the outer race of the bearing is properly
positioned and will align with the retaining pin (B) in
the crankcase.

REED VALVE ASSEMBLY
1. Inspect the reed valves, stoppers, and valve blocks
for cracks or any deterioration.
XM227
2. Wash the reed valves, stopper, and cage assembly in
parts-cleaning solvent and blow dry.
3. Inspect the reed-to-seat clearance. Using a feeler
gauge, measure the clearance. Clearance must be less
than 0.008 in. If clearance is not within specifica-
tions, replace the reed valve.
4. To assemble, place the reed valves on the cage with
its clipped corner positioned to the lower right hand
corner of the cage. Place the reed stopper assembly
into position and secure with the screws tightened to
10 in.-lb (± 2.2 in.-lb).

Measuring Critical
Components
CYLINDER TRUENESS
1. Measure each cylinder in locations from front to
back and side to side top and bottom of the cylinder
for a total of four readings.
CWI-077
2. The trueness (out-of-roundness) is the difference
between the highest and lowest reading. Maximum
trueness (out-of-roundness) must not exceed 0.004
in.
PISTON SKIRT/CYLINDER CLEARANCE
1. Measure the piston skirt diameter 10 mm from the
bottom of the piston. Once the measurement is final,
lock the micrometer.
2. Position a bore gauge between the micrometer points
and move it from top to bottom and side to side to
find zero; then adjust the gauge to zero.
