Bolts and Nuts







Bolts and Nuts






Tighten and loosen the bolts or nuts for the covers and housings in a diagonal sequence.

The tightening specification stated applies to non-lubricated nuts and bolts.

Use a wire brush to clean the threads of bolts that were installed using liquid locking fluid. Install the bolts using liquid locking fluid (AMV 185 100 A1).

Clean all threaded holes with a thread tap to remove any locking fluid residue. Otherwise the bolts could shear the next time they are removed.

Always replace self-locking nuts and bolts.
