Clutch Master Cylinder
Description
The clutch master cylinder mounts to the clutch pedal
and consists of a piston and cylinder housing, an actu-
ating push rod, and an interconnecting hydraulic line.
Fluid is supplied to the clutch master cylinder via the
brake fluid reservoir.
Operation
When the clutch pedal is depressed, the push rod moves the piston in the master cylinder, displacing fluid through
the hydraulic line and into the release bearing. The release bearing is extended and forces the fingers of the clutch
diaphragm springs to move. As the fingers move, they release the clamping pressure on the clutch disc between the
clutch pressure plate and the flywheel. The clutch becomes disengaged as this pressure is released. When the clutch
pedal is released, the system hydraulic pressure is released. This allows the force of the clutch diaphragm springs to
return themselves to their original position, re-clamping the clutch disc between the flywheel and the clutch pressure
plate. Also, the release bearing is forced to return, which reverses the movement of the hydraulic system and returns
the pedal to its original position against the up stop.
Removal & Installation
1. Disconnect hydraulic supply line to clutch master
cylinder (1) to completely drain clutch master cylin-
der and tubing.
2. Disconnect hydraulic line (1) and drain fluid into
suitable container.
