DRY CLEANING SOLVENT

3. Use penetrant kit (WP 0045, item 27) to check for cracks in bolt (4) as follows:

a. The area to be inspected must be clean, free of oil, etc. Spray a small amount of remover on the

area to be inspected, let dry and wipe off with a wiping rag.

b. Spray penetrant (only enough to wet the area) on the area of the bolt (4) to be inspected.

c. Spray developer over the penetrant and let the developer work. Cracks will be indicated by a

change in color where there is a crack. If there are cracks, the component is unserviceable.

d. Pay close attention to the area where the locking lugs (10) meet the body.

e. If there are no cracks, spray remover on the area; let dry and wipe off with a wiping rag. Oil the

area to prevent corrosion.

f. Replace bolt assembly if bolt (4) is defective.
