Spray penetrant (only enough to wet the area) on the area of the bolt (1) to be inspected.

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.

Pay close attention to the area where the locking lugs meet the body.

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.

Replace bolt assembly if bolt (1) is defective.
