Bolts and Nuts







Bolts and Nuts






Loosen or tighten bolt and nuts for the covers or housings diagonally.

The tightening specification stated apply 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 185 101 A1).

Clean the threaded holes for the self locking bolts or for the bolts coated with the locking fluid. Otherwise there is a risk that the bolts will shear the next time they are removed.

Always replace self locking nuts and bolts.
