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 (page 15-5).
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 (page 15-5) and recheck the
clearance.
If the clearance is still more than the service limit with
the new piston pin, replace the piston (page 15-5).
PISTON RING SIDE CLEARANCE
Measure the clearance between each piston ring and
ring groove of the piston using feeler gauge.
If the calculated clearance is more than the service
limit, replace the piston ring (page 15-5) and recheck
the clearance.
If the clearance is still more than the service limit with
the new piston ring, replace the piston (page 15-5).
PISTON RING WIDTH
Measure each piston ring width.
If any of the measurements is less than the service
limit, replace the piston rings (top, second, oil) as a set
(page 15-5).
