Clutch: Description and Operation

The clutch control system used on R/V models consists of a clutch master cylinder, slave cylinder and a connecting hose. Pressure applied to the master cylinder pushrod from the clutch pedal forces the master cylinder plunger and seal assembly along the cylinder bore. As the plunger moves, the seal closes off the cylinder bore fluid inlet and hydraulic pressure is created which operates the slave cylinder. The slave cylinder, in turn, operates the clutch release fork through a short pushrod.
When the clutch pedal is released, the combination of fluid and return spring pressure moves the piston and seal assembly back until it reaches a stop in the bore. When the piston contacts the stop, the seal is behind the cylinder bore inlet (recuperation hole) and pressure is released from the system.
