2) Clearance
Measure the clearance between the
piston pin and connecting rod bushing,
and replace either of them, whichever
damaged more, if the measured value is
beyond the limit.
Standard Limit
0.003 ∼ 0.015 mm
0.08 mm
3) Condition check
Check the engaged condition of the
piston and piston pin. If it is possible to
force the pin into the piston heated with
piston heater, the piston is normal. When
replacing the piston, be sure to replace
the piston pin together.
(5) Connecting rod inspection
1) Distorsion
Check the connecting rod for distortion.
As shown in the figure below, install the
connecting rod to the connecting rod
tester, and check for distortion using a
feeler gauge. If the connecting rod is
found distorted, never re-use it but
replace with a new one.
2) Holes alignment (parallelism)
Measure the alignment of the
connecting rod piston pin bushing holes
with connecting rod big end holes. At
this time also, use both connecting rod
tester and feeler gauge.
Standard Limit
0.05 mm 0.1 mm or less
M1106
M1107
feeler gauge
