PISTON SKIRT O.D.
Measure and record the piston skirt O.D. at a point 10
mm (0.4 in) from the bottom of the skirt and 90° to the
piston pin bore.
If the measurement is less than the service limit,
replace the piston.
Inspect the cylinder sleeve I.D. (page 13-6).
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 and recheck the clearance.
If the clearance is still more than the service limit with a
new piston, replace the cylinder barrel.
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.
Inspect the piston pin O.D. (page 13-8).
