The hydraulic clutch mechanism engages and disengages the clutch system.

The clutch release system consists of the following components:

A pushrod controls the clutch master cylinder. The cylinder is mounted to the front of the dash. The clutch actuator cylinder assembly is mounted to the side the clutch housing.

The clutch hydraulic system is serviced as 2 components, the clutch master cylinder assembly and the clutch actuator cylinder assembly, 2 fluid pipes and 1 fluid hose.

Depressing the clutch pedal moves a piston inside the clutch master cylinder and displaces hydraulic clutch fluid to the clutch actuator cylinder. A hydraulic force is developed from the release bearing pressing on the diaphragm spring. The force of the diaphragm spring on the clutch disc decreases as the force of the release bearing increases. This process continues until the clutch is disengaged. The hydraulic clutch system does not require adjustment.

When adding fluid or refilling the system after service operations, use Hydraulic Clutch Fluid GM P/N 12345347 (Canadian P/N 10953517) or an equivalent fluid that meets DOT 3 specifications only.
