PISTON AND CYLINDER ASSEMBLY MAINTENANCE - CONTINUED
INSPECTION - CONTINUED
Inspect backs of bearing shells for bright spots. If such spots are present, replace bearing shells. Inspect connecting rod
bearing bores for burrs or foreign particles.
Install new upper and lower connecting rod bearing shells if new crankshaft is used.
Using micrometer and ball attachment, measure thickness of connecting rod bearing shell (6). Minimum thickness of
worn standard connecting rod bearing shell should not be less than 0.1215 in (3.086 mm). If either upper or lower con-
necting rod bearing shell of connecting rod set is less than minimum thickness, replace both bearing shells.
Examine cylinder liner for cracks, scoring, glazing, ring ridge formation, and cavitation erosion. If any of these condi-
tions are present, liner must be discarded.
Examine outside diameter of liner for fretting at flange and cylinder block bore area. If light fretting is present, surface
can be restored with abrasive cloth or flat stone.
Measure cylinder as follows:
0.984 in (25 mm)
0.394 in (10 mm)
6.30 in (160 mm)
9.25 in (235 mm)
