Clutch: Description and Operation
CLUTCH COMPONENTS- The clutch mechanism consists of a single, dry type clutch disc and a diaphragm style clutch cover.
- A sleeve-type release bearing is used to engage and disengage the clutch cover pressure plate. The bearing is lubricated during manufacture and is a sealed unit.
- The release bearing is operated by a pivoting release fork in the clutch housing. The fork pivots on a ball stud within the housing. The release fork is actuated by a hydraulic slave cylinder. The slave cylinder is operated by a clutch master cylinder connected to the clutch pedal.
- The clutch disc has cushion springs in the disc hub. The clutch disc facing is riveted to the hub. The facing is made from a non-asbestos material.
- The clutch cover pressure plate is a diaphragm type unit with a one-piece diaphragm spring and multiple release fingers. The pressure plate release fingers are preset during manufacture and are not adjustable.
- The transmission input shaft is supported in the crankshaft by a pilot bearing.
HYDRAULIC CLUTCH LINKAGE
- A hydraulic linkage is used to operate the clutch release fork and bearing. The linkage consists of a remote fluid reservoir, a clutch master cylinder, clutch slave cylinder, and interconnecting fluid lines.
- The master cylinder is connected to the clutch pedal. The slave cylinder is connected to the clutch release fork. The clutch master cylinder is mounted on the drivers side of the dash panel next to the brake booster.
- The clutch master cylinder push rod is connected directly to the clutch pedal.
- The factory installed hydraulic linkage has a quick disconnect at the slave cylinder. This fitting should not be disconnected or tampered with. The hydraulic linkage is serviced as an assembly only. The individual components that form the linkage assembly cannot be overhauled or serviced separately.
CLUTCH HYDRAULIC FLUID
- If inspection or diagnosis indicates additional fluid may be needed, it will be necessary to replace the complete hydraulic linkage assembly.
