PISTON SKIRT O.D.
Measure and record the piston O.D. at a point 10 mm
(0.4 in) from the bottom of the skirt and 90 degrees to
the piston pin bore.
If the measurement is less than the service limit,
replace the piston (page 15-5).
PISTON-TO-CYLINDER CLEARANCE
Subtract the piston skirt O.D. from the cylinder sleeve
I.D. to obtain the piston-to-cylinder clearance.
If the calculated clearance is more than the service
limit, replace the piston (page 15-5) and recheck the
clearance.
If the clearance is still more than the service limit with
the new piston, replace the cylinder barrel (page 15-4).
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 (page 15-5).
