Cleaning and Inspection

Cleaning
Identify reusable bearings so they can be installed in their original locations.

CAUTION: Do not scrape gum or varnish deposits from the bearings or damage., to the bearings may occur.

Clean the bearings and caps thoroughly in solvent and dry them with compressed air.





Inspection
Inspect each bearing carefully. Replace bearings that have scored, chipped or worn surfaces. Typical examples of unsatisfactory bearings and their causes are shown in the following illustration on 3.0L (2V) and 3.0L (4V) engines which use aluminum bearings. The copper-lead bearing base may be visible through the bearing overlay on and 3.4L SHO engines. The bearing is aluminum. If the base showing is less than 20 percent of the total area, the bearing is not excessively worn. It is not necessary to replace the bearing if the bearing clearance is within recommended limits. Check the clearance of bearings that appear to be satisfactory with Plastigage 303-D031 (D81L-6002-13) or equivalent.
