3) Piston ring side clearance
z Fit the compression ring and oil ring in
the piston ring groove.
z With a feeler gauge, measure side
clearance of each ring, and replace
either the ring or piston if the measured
value is beyond the specified limit.
Standard Limit
Top ring
- -
2nd ring
0.07 ∼ 0.102 mm
0.15 mm
Oil ring
0.05 ∼ 0.085 mm
0.15 mm
4) Piston ring tension
With a tension tester, measure piston
ring tension. Replace the piston ring if
the measured value is beyond the limit.

(4) Piston pin inspection
1) Wear
Measure the amount of wear on the
piston pin at the points as shown. The
