Bolts and Nuts






Loosen or tighten bolt and nuts on covers or housings diagonally.

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 locking fluid. Install the bolts using liquid locking fluid (AMV 185 101 A1).

Use a thread tap to clean all threaded holes containing self-locking bolts to remove any locking fluid residue. Otherwise the bolts could shear the next time they are removed.

Always replace self-locking nuts and bolts.
