Bearing Clearance

WARNING:
Cooling Fan Operation Hazard
To avoid the possibility of personal injury or damage to the vehicle, do not operate the engine with the hood open until the fan has first been examined for possible cracks and separation.

NOTE:
Specifications and Limits
Specifications show the expected minimum or maximum condition. If a component fails to meet the specifications, it is necessary to replace or refinish. If the component can be refinished, wear limits are provided as an aid to making a decision. Any component that fails to meet specifications and cannot be refinished must be replaced.





NOTE: Crankshaft main bearing journals must be within specification before checking journal clearance.

1. Remove the crankshaft main bearing caps and bearings.
2. Lay a piece of Plastigage D81L-6002-B off-center and fully across the face of each crankshaft main bearing surface.

NOTE: Do not turn the crankshaft (6303) while doing this procedure.

3. Install and remove the crankshaft main bearing cap.
4. Verify the crankshaft journal clearance.
Clearance: 0.020-0.065 mm (0.0008-0.0026 inch).

5. If it is out of specification, replace as necessary.
