Connecting Rod Bearing Journal-to-Bearing Clearance

Connecting Rod Bearing Journal-to-Bearing Clearance

NOTE: The crankshaft connecting rod journals must be within specifications before checking the connecting rod bearing journal clearance.

1. Remove the connecting rod bearing cap and connecting rod bearing.

2. Position a piece of plastigage across the face of the connecting rod bearing surface.





3. NOTE: Do not turn the crankshaft during this step.

Install and tighten to specifications, then remove the connecting rod bearing cap.

- For additional information, refer to Engine Engine - Assembly.

4. Measure the plastigage to get the connecting rod bearing journal clearance. The plastigage should be smooth and flat. A changing width indicates a tapered or damaged connecting rod or connecting rod bearing. For additional information, refer to Engine.
