i. Measure the Plastigage at its widest point.
Standard oil clearance: 0.021 to 0.047 mm (0.0008 to 0.0019 in.) Maximum oil clearance:
0.059 mm (0.0023 in.)
If the oil clearance is greater than the maximum, replace the bearings. If necessary, replace the
crankshaft.
HINT:If using a standard bearing, replace it with one that has the same number. If the number of
the bearing cannot be determined, select the correct bearing by adding together the numbers
imprinted on the connecting rod cap and crankshaft, then select the bearing with the same number
as the total. There are 6 sizes of standard bearin
gs, marked 2, 3, 4, 5, 6 and 7.

5.REMOVE W/PIN PISTON SUB-ASSY
a. Check the fit between the piston and piston pin.
1. Try to move the piston back and forth on the piston pin.
If any movement is felt, replace the piston and pin with a new piston and pin set.
