b. Cleaning and Drying
1. Clean all parts with an approved petroleum
based cleaner.

spinning with compressed air. This can
damage mating surfaces due to lack of
lubrication.
3. After drying, components should be lightly
coated with oil or rust preventive to protect
them from corrosion.
c. Inspection and Replacement
1. Replace any bearing race assembly
(4, Fig. 5.10) if it is worn, pitted, or damaged.
2. Replace cross assemblies (3) that are worn or
damaged.
