4) Piston pin inspection
(1) Wear
Measure the amount of wear on the piston pin at the
points as shown. The measured values are beyond
the limit (0.08 mm or greater), replace the pin.
(2) Clearance
Measure the clearance between the piston pin and
connecting rod bushing, and replace either of them,
whichever damaged more, if the measured value is
beyond the limit.
(3) Condition check
Check the engaged condition of the piston and piston
pin. If it is possible to force the pin into the piston
heated with piston heater, the piston is normal. When
replacing the piston, be sure to replace the piston pin
together.
5) Connecting rod inspection
(1) Distorsion
Check the connecting rod for distortion. As shown in the figure below, install the connecting rod to the
connecting rod tester, and check for distortion using a feeler gauge. If the connecting rod is found
distorted, never re-use it but replace with a new one.
