NOTE:
Refer to appropriate article in Engine
for the specification.
NOTE:
The crankshaft connecting rod journals must be within specifications to check the connecting rod bearing journal clearance.
- Remove the connecting rod bearing cap.
- Position a piece of Plastigage across the bearing surface.
- Install and tighten to specifications, then remove the connecting rod bearing cap.
- 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.
NOTE:
Do not turn the crankshaft during this step.
