Connecting Rod Bearing





Measure the Plastigage at its widest point.
Standard oil clearance:
1ZZ-FE Engine: 0.028 - 0.060 mm (0.0011 - 0.0024 inch)
2ZZ-GE Engine: 0.028 - 0.052 mm (0.0011 - 0.0020 inch)
Maximum oil clearance; 0.08 mm (0.0031 inch)
If the oil clearance is greater than maximum, replace the bearings. If necessary, grind or replace the crankshaft.
