V almet 6000---8000 Hi---Trol ---models are equipped with a hy-
draulic coupling between the flywheel and the clutch. The
mechanical clutch (except the disc) and its adjusting values
are the same as on models without the hydraulic coupling
(see figure 1).
The hydraulic coupling is maintenance---free. It is not even
necessary to check the oil level.
