Connecting Rod Clearance Inspection

CONNECTING ROD CLEARANCE INSPECTION
1. Measure the side clearance at the large end of the connecting rod using a feeler gauge.
^ If it is at the maximum specification or more, replace the connecting rod or crankshaft.





Connecting rod large end side clearance
Standard
0.14-0.36 mm (0.0056-0.0141 in)
Maximum
0.435 mm (0.0172 in)

2. Using a plastigauge, measure the oil clearance at the large end of the connecting rod. If it is at the maximum specification or more, replace the bearing or grind the crank pin and use oversize bearings so that the specified clearance is obtained.

Note
^ Cut the plastigauge as wide as the connecting rod bearing width, place it parallel to the crankshaft, keeping away from the oil hole.
