13. INSPECT PISTON PIN FIT
At 60
°
C (140
°
F), you should be able to push the piston pin into
the piston pin hole with your thumb.
14. INSPECT CONNECTING ROD ALIGNMENT
Using a rod aligner and feeler gauge, check the connecting rod
alignment.
Check for out-of-alignment.
Maximum out-of-alignment:
0.05 mm (0.0020 in.) per 100 mm (3.94 in.)
If out-of-alignment is greater than maximum, replace the con-
necting rod assembly.
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 connecting rod as-
sembly.
15. INSPECT PISTON PIN OIL CLEARANCE
(a) Using a caliper gauge, measure the inside diameter of the
connecting rod bushing.
Bushing inside diameter:
22.005 - 22.014 mm (0.8663 - 0.8667 in.)
(b) Using a micrometer, measure the piston pin diameter.
Piston pin diameter:
21.997 - 22.006 mm (0.8660 - 0.8664 in.)
(c) 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 bush-
ing. If necessary, replace the piston and piston pin as a set.
