General information
PT equipped models are equipped with a hydraulically actuated diaphragm clutch. The clutch disc is clamped between the diaphragm type pressure plate and the engine flywheel by the pressure generated by the spring. The splined hub of the clutch disc rotates on the transmission input shaft; The pressure plate cover is bolted to the engine flywheel.
When the clutch pedal is depressed, fluid pressure is created in the master cylinder, which displaces the pusher from the slave cylinder, setting the engagement lever and release bearing in motion. As the release bearing presses against the pressure plate petals, the pressure on the clutch disc is released, thereby disengaging the engine from the transmission.
The models covered in this manual use two different types of clutch discs, depending on the type of flywheel. On models with a conventional disc type flywheel, the clutch disc has integral leaf springs and damping springs. Spring springs - located between the friction surfaces of the disc - soften the blow when the clutch is engaged; damping springs - help to dampen the pulsation of the engine during rotation. On models with two-piece flywheels, damping springs are built into the flywheel.
