Bolts And Nuts

Always loosen or tighten bolts and nuts on covers and housings diagonally.
The tightening specifications stated apply to non-oiled nuts and bolts.
Always replace self-locking nuts and bolts.
Make sure the contact surfaces and visible surfaces on the nuts and bolts are waxed after assembling.
Use a thread cutter to clean all threaded holes containing self-locking bolts to remove any locking compound residue. Otherwise the bolts could shear the next time they are removed.
