(f) Using vernier calipers, measure the minimum diameter of
the compressed bolt at the measuring point.
Standard diameter:
8.400 - - 8.600 mm (0.3307 - - 0.3385 in.)
Minimum diameter: 8.20 mm (0.3228 in.)
If the diameter is less than minimum, replace the connecting rod
bolt.
(g) Inspect the piston pin oil clearance.
(1) Using caliper gauge, measure the inside diameter
of the connecting rod bushing.
Bushing inside diameter:
34.012 - - 34.024 mm (1.3391 - - 1.3395 in.)
(2) Using a micrometer, measure the piston pin diame-
ter.
Piston pin diameter:
34.000 - - 34.012 mm (1.3386 - - 1.3391 in.)
(3) Subtract the piston pin diameter measurement from
the bushing inside diameter measurement.
Standard oil clearance:
0.008 - - 0.0016 mm (0.0003 - - 0.0006 in.)
Maximum oil clearance: 0.03 mm (0.0012 in.)
If the oil clearance is greater than maximum, replace the bush-
ing. If necessary, replace the piston and piston pin as a set.
10. INSPECT RH AND LH BALANCE S HAFT
(a) Using cylinder gauge, measure the inside diameter of the
balance shaft bearing.
Bearing inside diameter (from front side):
