CLUTCH COMPONENTS
The clutch mechanism in BR models with a gas or
diesel engine consists of a single, dry-type clutch disc
and a diaphragm style clutch cover. A hydraulic link­
age is used to engage/disengage the clutch disc and
cover.
The transmission input shaft is supported in the
crankshaft by a bearing. A sleeve type release bear­
ing is used to engage and disengage the clutch cover
pressure plate.
The release bearing is operated by a release fork in
the clutch housing. The fork pivots on a ball stud
mounted inside the housing. The release fork is actu­
ated by a hydraulic slave cylinder mounted in the
housing. The slave cylinder is operated by a clutch
master cylinder mounted on the dash panel. The cyl­
inder push rod is connected to the clutch pedal.
The clutch disc has damper springs i n 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 with
a one-piece spring and multiple release fingers. The
pressure plate release fingers are preset during man­
ufacture and are not adjustable.
CLUTCH DISC APPLICATION
Two clutch disc diameters and four different thick­
nesses are used.
A 281 mm (11 in.) diameter clutch disc is used with
a 3.9L, 5.2L, or 5.9L gas engines (Fig. 1) and (Fig. 2).
