B. In.pect connecting rod boltl
Using vernier calipers. measure the tension portion
diameter.
Standard diameter:
8.300 - 8.400 mm (0.3268 - 0.3307 In.)
Minimum diameter:
7.95
mm
(0.3130 In.)
If the diamet.r is less than
minimUm,
replace the

C. Inspect piston pin oil clearance
(a) Using caliper gauge. measure the inside diameter of
the connecting rod bushing.
Bushing inside diameter:
33.008 - 33.020 mm (1.2995 - 1.3000 in.)
(b) Using micrometer. measure the piston pin diameter.
PI,ton pin diameter:
33.000 - 33.012 mm (1.2992 - 1.2997 In.)
(e) Subtract the piston pin diameter measurement from
the bushing inside diameter measurement.
St.nd.rd oil cl••r.nce:
0.004 - 0.012 mm (0.0002 - 0.0005 in.)
M.ximum oil cl••r.nce:
0.03 mm (0.0012 in.)
If the oil clearance is greater than maximum. replace
the bushing. If necessary. replace the piston and
piston pin as a set.
D. If necessary. raplace connecting rod bushing
(a) Using SST and a press, press out the bushing.
