PISTON PIN AND PIN BORE
Using a caliper gauge, measure the piston pin bore inside
diameter, and using a micrometer measure the piston pin
outside diameter.
If the difference between these two meas-
urements is more than the limits, replace both piston and
piston pin.

CONROD DEFLECTION AND
CONROD BIG END SIDE CLEARANCE
Wear on the big end of the conrod can be estimated by
checking the movement of the small end of the rod. This
method can also check the extent of wear on the parts of
the conrod's big end.
