Pistons
Inspection
1.Check the piston for distortion or cracks,
NOTE: lf a cylinder is bored. an oversized piston
must be used.
Measure the piston diameter at a distance A from
bottom of the skirt.

3. Calculate the difference between the cylinder bore
diameter (see page 7-16) and the piston diameter.

lf the clearance is near or exceeds the service limit,
inspect the piston and cylinder block for excessive
wear.

lf the measurements in any cylinder are beyondthe Oversize Bore Service Limit, replace the block.
lf the block is to be rebored. refer to piston Clear-ance Inspection (see page 7-15) after reboring.
NOTE: Scored or scratched cylinder bores must behoned.

2. Zero the dial indicator to the piston pin diameter'
Measure the diameter of the piston pin.

3. Measure the piston pin-to-piston clearance.
NOTE: Check the piston for distortion or cracks.
lf the piston pin clearance is greater than 0.024 mm
(0.0009 jn), remeasure using an oversized piston
pin.
Piston Pin-to-Piston Clearance:
Standard (New): 0.010 - 0.022 mm
(0.0004 - 0.0009 in)
Check the difference between the piston pin diame-
ter and the connecting rod small end diameter'
