5. CHECK PISTON PIN FIT
At
ao·c
(176.F) you should be able to push the pin into
the piston with your thumb.
If the pin can be installed at a lower temperature, replace
the piston and pin as a set.
6. INSPECT CONNECTING RODS
(a) Using a rod aligner and thickness gauge, check the
connecting rod alignment.
• 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 connecting
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 assembly.
(b) Using a caliper gauge, measure the inside diameter
of the connecting rod bushing.
Bushing inside diameter: 22.012- 22.027 mm
(0.8666- 0.8672 in.)
(c) Using a micrometer, measure the piston pin diame-
ter.
Piston pin diameter: 22.004- 22.019 mm
(0.8663- 0.8669 in.)
(d) 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: 0.03 mm (0.0012 in.)
If the oil clearance is greater than maximum, replace the
connecting rod bushing. If necessary, replace the piston
and piston pin assembly.
