GENERAL
CLUTCH
The clutch is a single dry plate type, comprising clutch
disc, pressure plate assembly and release bearing.
The clutch plate consists of a resilient steel disc attached
to a splined hub sliding on the clutch shaft. The clutch
facings are riveted to both faces of the disc.
The pressure plate assembly, which consists of the clutch
cover and a cast pressure plate under pressure from spiral
springs, is attached to the flywheel by means of bolts.
The coil springs are kept in place by guides on the pres-
sure plate and the clutch cover. Three clutch release levers
are carried on struts and riveted to the clutch cover. The
pressure plate assembly is held together by the three clutch
levers, which are secured by lugs on the struts. A spring
loaded steel disc, against which the release bearing is pres-
sed when declutching, rests on the inner ends of the clutch
levers.
The release bearing comprises a ball hearing held in a bear-
ing housing, which is retained in the clutch fork by springs.
A teflon coating on the ball bearing presses against
the release plate when declutching. The power is transmit-
ted from the flywheel via the clutch cover and pressure
plate to the clutch disc, and from there to the clutch
shaft. One end of the clutch shaft is carried in a self lubri-
eating bearing in the crankshaft, and the other in a needle
bearing in the gear box primary shaft. In the middle of the

clutch shaft is a ball bearing with radial clearance in the
clutch cover but locked axially by means of retaining rings.
Axial guiding of the clutch shaft is provided for by this
bearing. The pressure plate is pressed against the clutch
disc by the coil springs, and is when declutching moved
away from the flywheel by the three clutch levers. The
release bearing is supported by the clutch fork which is
attached to the vertical release shaft carried in the gear
box cover. The clutch operation is hydraulic. It com-
prises a master cylinder that is actuated by the clutch
pedal. A hose connects the master cylinder to a slave cyl-
inder which influences the clutch lever and release bear-
mg.
TRANSMISSION
The transmission is designed for front wheel drive and
arranged so that all shafts with their gears, free wheel,
differential and inner universal joint form a complete
unit.
The transmission has synchromesh for all forward gears,
whereas the reverse gear comprises a sliding gear wheel.
The transmission train comprises an input clutch shaft,
freewheel, primary shaft, countershaft, pinion shaft, dif-
ferential and inner universal joints. The shafts are carried
in ball bearings in the gear box cover. The unit is connec-
