Connecting Rod Bearing

Connecting Rod Bearing Oil Clearance
Standard oil clearance:
STD: 0.032 - 0.050 mm (0.0013 - 0.0020 inch)
U/S 0.25: 0.033 - 0.073 mm (0.0013 - 0.0029 inch)
Maximum oil clearance: 0.10 mm (0.0039 inch)

If the oil clearance is greater than maximum, replace the bearings. If necessary, grind or replace the crankshaft.








NOTE: If using a standard bearing, replace with one having 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 and crankshaft, then selecting the bearing with the same number as the total.There are 5 sizes of standard bearings, marked "2","3", "4", "5" and "6" accordingly.
