ROCKER ARM SHAFT BEARING I.D.
Measure the rocker arm shaft bearing I.D.
If the measurement is more than the service limit,
replace the cylinder (page 14-5).
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 14-6).
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 (page 14-6) and recheck the
clearance.
If the clearance is still more than the service limit with
the new piston, replace the cylinder (page 14-5).
