Connecting Rod Bearing

Connecting Rod Bearing
Standard oil clearance: 0.027 - 0.053 mm (0.0011 - 0.0021 inch)
Maximum oil clearance: 0.065 mm (0.0026 inch)
If the oil clearance is greater than maximum, replace the bearings. If necessary, replace the crankshaft.





HINT: If using a standard bearing, replace it 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 cap and crankshaft, then selecting the bearing with the same number as the total. There are 6 sizes of standard bearings, marked "2", "3", "4", "5", "6" and "7".





EXAMPLE:
Connecting rod cap "3" + Crankshaft.
= Total number 4 (Use bearing "4")
