Connecting Rod Bearing Journal Clearance

Special Tools:

NOTE: The piston connecting rod journals must be within specification to check the connecting rod bearing journal clearance.





1. Position a piece of Plastigage off center across the bearing surface.
2. Install and tighten to specification, then remove the connecting rod bearing cap.

NOTE: Do not turn the crankshaft during this step.





3. 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 main bearing or connecting rod.
