ROCKER ARM INSPECTION
1. To check the rocker arms for excessive free-play, follow the
steps in “Exhaust Rocker Arm Pivot Free-Play Inspection”
on
. Repeat the steps for the intake valve.
2. Measure the Rocker Arm Shaft O.D.
PISTON-TO-CYLINDER CLEARANCE
INSPECTION
1. Measure and record the Cylinder I.D. at three levels in both
the “X” axis (perpendicular to crankshaft) and the “Y” axis.
Take the maximum reading to determine cylinder wear and
taper.
If the cylinder I.D. is worn beyond the service limit, it must
be replaced. Do not hone the cylinder.
2. Measure and record the Piston O.D. at a point
10 mm (0.4 in) from the bottom of the skirt and 90° to the
piston pin bore.
3. Subtract the Piston O.D. from the Cylinder I.D. to
determine the Piston-to-Cylinder clearance.
Do not hone the aluminum cylinder when replacing rings.
