Oil Clearance

Remove oil or foreign matter from the bearing and
crankshaft.
Cut the plasti-gauge to the same width as the
bearing. Place it on the crankshaft at 1. Avoid the oil
hole.

Assemble the connecting rod and connecting rod
cap and tighten to the specified torque. All engines 36
ft. lbs. - 40 ft. lbs. (49 N·m - 54 N·m).
NOTE: Never rotate the connecting rod.
Remove the connecting rod cap. Measure the oil
clearance (plasti-gauge) with the scale printed on the
gauge bag.
NOTE: Measure the widest area.
Standard Play: 0.001″ - 0.003″ (0.035 mm -
0.085 mm)
Allowable Limit: 0.0078″ (0.2 mm)
If the oil clearance exceeds the allowable limit,
replace the bearing or grind the crankshaft and use
an oversize bearing.
NOTE: When grinding the outside diameter of the
crankshaft, be sure that the oil clearance is correct
before reassembly.
