PISTON PIN O.D.
Measure and record the piston pin O.D. at three points (both ends
and middle). Take the minimum reading to determine piston pin
O.D.
If the measurement is less than the service limit, replace the piston
pin.
PISTON PIN BORE I.D.
Measure and record the piston pin bore I.D. of the piston.
If the measurement is more than the service limit, replace the
piston.
PISTON PIN-TO-PISTON PIN BORE CLEARANCE
Subtract the piston pin O.D. from the piston pin bore I.D. to obtain
the piston pin-to-piston pin bore clearance.
If the calculated clearance is more than the service limit, replace
the piston pin and recheck the clearance.
If the clearance is still more than the service limit with the new
piston pin, replace the piston.
CONNECTING ROD SMALL END I.D.
Measure the connecting rod small end I.D.
If the measurement is more than the service limit, replace the
connecting rod.
