INSPECT CONNECTING ROD
Inspect connecting rod alignment
Using a rod aligner and feeler gauge, check the con-
necting rod alignment.
0 Check for bend.
Maximum bend:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If bend is greater than maximum, replace the connect-
ing rod assembly.
I Check for twist
Maximum twist:
0.15 mm (0.0059 in.) per 100 mm (3.94 in.)
If twist is greater than maximum, replace the connect-
ing rod assembly.
Inspect piston pin oil clearance
Using a caliper gauge, measure the inside diameter of
the connecting rod bushing.
Bushing inside diameter:
22.005 — 22.017 mm (0.8663 —- 0.8668 in.)
Using a micrometer, measure the piston pin diameter.
Piston pin diameter:
21.997 — 22.009 mm (0.8660 — 0.8665 in.)
Subtract the piston pin diameter measurement from
the bushing inside diameter measurement.
Standard oil clearance:
0.005 — 0.011 mm (0.0002 — 0.0004 in.)
Maximum oil clearance:
0.05 mm (0.0020 in.)
If the oil clearance is greater than maximum, replace
the bushing. If necessary, replace the piston and
piston pin as a set.
