PISTON PIN AND PIN BORE
Measure
the
piston
pin
bore diameter using
the
small bore
gauge.
If
the
diameter exceeds
the
service
limit,
replace
the
piston
with
a
new one.

Measure
the
piston
pin
outside diameter
at
three positions
using the micrometer.
If any
measurement exceeds the service
limit,
replace the piston pin
with
a
new one.

CONROD
SMALL END
I.D.
Measure
the conrod small
end
inside diameter using the small
bore
gauge.
If
the
conrod small
end
inside diameter exceeds
the
service
limit,
replace the conrod
with
a
new one.

CONROD
DEFLECTION AND 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
be
used
to check the extent
of
wear on the parts
of
the conrod's
big
end.

Push
the big end of the
conrod
to one
side
and
measure
the
side clearance using
a
thickness
gauge.
If
the
clearance
exceeds the service
limit,
replace the crankshaft assembly
with
a new
one or
bring the deflection
and
the side clearance
within
the
service
limit
by
replacing
the
worn parts (conrod,
big end
bearing, crank pin, etc.)
with
new ones.
