Nuts, Bolts






Nuts, Bolts

Loosen and tighten bolts or nuts for securing covers and housings in diagonal sequence.

Do not cant, and loosen and tighten especially sensitive parts - e.g. Mechatronic - in diagonal sequence in stages.

The tightening torques stated apply to non-oiled nuts and bolts.

Using a wire brush, clean threads of bolts which are secured with locking compound. Then insert bolts with AMV (185 100 A1).

All threaded bores in which self-locking bolts are threaded must be cleaned of remaining locking fluid using a tap. Otherwise there is danger that the bolts may shear when removed again.

Always replace self-locking nuts and bolts.
