2-42. GENERAL DISASSEMBLY INSTRUCTIONS.
a.
Cleanliness. Work area must be as clean as possible to prevent contamination to components.
Self-locking fasteners that are loosened must be replaced, not tightened.
b.
Locking Parts. Replace all lockwire, lockwashers, cotter pins and locknuts at time of reassembly.
c.
Expendable Parts. All gaskets, packings and seals removed during repair must be discarded and replaced with
new parts.
d.
Removing Seals. Be sure all traces of oil, gaskets and sealants are removed from components. When
possible, use wood or plastic probes and scrapers to prevent damage to machined surfaces.

oil and cause engine malfunctions.
