Caution:

All front-mounted clutches are balanced with a balance quality of Q = 6.3!
If running after repairs is not smooth the clutch must be rebalanced with the limits contained in
the assembly drawing.

Balancing

All front-mounted clutchs are balanced with a balance quality of Q = 6.3! In the production of new parts in
our company the parts are well below the permissible limits. The wearing parts to be replaced in the event
of a repair are rotationally symmetric and experience has proven that they do not lead to an impermissible
or disturbing imbalance.

If contrary to expectation running is irregular the balancing must be checked. The assembly drawing is to
be referred to for the permissible imbalance data.
