PISTON/ROD INSPECTION
1. Measure piston pin bore.
Piston Pin Bore:
600: 0.00027” ± 0.00019”
(0.007 ± 0.005 mm)
700: 0.00059” ± 0.0002”
(0.015 ± 0.005 mm)
2. Measure piston pin O.D. Replace piston and/or
piston pin if out of tolerance.
Piston Pin Measurement Locations
Piston Pin O.D.
0.7874” -- .7872” (20 -- 19.995 mm)
3. Measure connecting rod small end ID.
Connecting Rod Small End I.D.
.789” -- .78841”. (20.030 -- 20.015 mm)
4. Measure piston ring to groove clearance by
placing the ring in the ring land and measuring
with a thickness gauge. Replace piston and rings
if ring-to-groove clearance exceeds service
limits.
