GENERAL DESCRIPTION

PUSH TYPE CLUTCH (MSG and MUA)

PULL TYPE CLUTCH (MUX)

RTW77CSF000601

7C-4 CLUTCH

The clutch assembly consists of the pressure plate, the clutch cover, the diaphragm spring pivot pin and the driven
plate assembly.
The clutch pedal is connected to the release bearing through the shift fork.
The driven plate assembly is installed between the flywheel and the pressure plate.
For models with MSG transmission and MUA transmission, the push-type clutch is used.
Diaphragm spring pressure holds the driven plate against flywheel and the pressure plate to provide the friction
necessary to engage the clutch.
Depressing the clutch pedal moves the shift fork against the release bearing.
The release bearing forces the diaphragm to overcome the force of the diaphragm spring and separate the driven
plate from the flywheel and pressure plate to disengage the clutch.
For model with MUX transmission, the pull-type clutch is used. The pull-type clutch is disengaged by pulling the
release lever (release bearing) to disengage the pressure plate.
