6.2.10. Piston pin
1) Wear
Measure the amount of wear on the
piston pin at the points as shown. If
the measured values are beyond the
limit (0.005 mm or greater), replace
the pin.
2) Clearance
Measure the clearance between the
piston pin and connecting rod bush,
and replace either of them, whichever
damaged more, if the measured
value is beyond the limit.
3) Condition check
Check the insertion condition of the piston and piston pin. If it is possible to force the pin
into the piston heated by piston heater, the piston is normal.
When replacing the piston, be sure to replace the piston pin together.
