5. Use a piston to push each ring squarely into cylinder
bore from bottom (push rings 25-50mm into cylinder).
6. Measure installed ring end gap with a feeler gauge and
compare to specification listed on page 8.3. If either
ring exceeds the service limit, replace ring set.
7. Install rings onto a clean piston. Push rings in until they
are flush with piston. Using a feeler gauge (A),
measure side clearances for the 1st & 2nd rings. If any
of clearances exceed limit, replace piston and piston
rings.
Piston Pin / Pin Bore Inspection
1. Measure piston pin hole I.D. in four locations with a
telescoping gauge. Record the smallest.
2. Measure piston pin O.D. at three locations. Record
largest measurement.
3. Calculate piston pin-to-piston clearance. Subtract pin
O.D. from pin hole I.D.
4. Measure connecting rod small end I.D. at two
locations.
5. Calculate connecting rod-to-piston pin clearance by
subtracting pin O.D from rod hole I.D.
6. Compare measurements to specifications listed on
page 8.3 and replace any worn parts.
