General Information

The hydraulic clutch control system consists of a pedal unit and a secondary cylinder, connected by a hydraulic hose and fastened with quick-disconnect clamps. The components of the system have been specially designed to use DOT 4 brake fluid. The pedal unit includes a hydraulic subassembly, composed of the main cylinder and reservoir, which can be removed from the pedal unit for service purposes. When the clutch pedal is depressed, the fluid in the main cylinder is forced through a hydraulic line to the secondary cylinder. The fluid pressure moves the secondary cylinder piston, pushing the plunger rod and clutch release lever, which disengages the clutch. The hydraulic system is self-adjusting.

Clutches are designed to absorb and dissipate more heat than encountered in typical operation. The temperatures developed in typical operation will not break down the clutch friction surfaces. However, if a clutch is slipped excessively, or asked to do the job of a fluid coupling, high temperatures develop quickly and destroy the clutch. Temperatures generated between the flywheel, driven discs, and pressure plates can be high enough to cause the metal to flow and the friction facing material to char and burn.

Heat and wear are practically nonexistent when a clutch is fully engaged. But during the moment of engagement, when the clutch is picking up the load, it generates considerable heat. An improperly adjusted or slipping clutch will rapidly generate sufficient heat to destroy itself.

To ensure long service life of the clutch; start in the right gear, be alert to clutch malfunctions, and know when to adjust the clutch.
