Adjustment of clutch-pedal free movement
The clearance between release bearing and release plate
is gradually decreased by wear on the clutch facings.
Adjust the clutch pedal free movement with the screw
on the clutch housing. This screw is located on the oppo-
site side in relation to the slave cylinder. The free move-
ment is increased by slackening the screw (turning to the
lett). The clearance is checked by pressing the slave cyl-
inders connection to the clutch arm. A movement of
0.16" (4 mm) here, gives the correct clutch clearance.

Master cylinder
General
The master cylinder is a cast unit containing the cylinder
and fluid reservoir.
The cylinder consists of a housing of light alloy with a
surface-polished bore and with an inner assembly, made
up to the push-rod, cupped washer, lock ring, piston, end
seal, piston seal, spring retainer, piston-return spring,
valve spacer, elastic washer, valve spindle and valve seal.
The open end of the cylinder is protected by a rubber
dust cap.
When the piston returns to the position of rest, the valve
which affords a seal in the bottom of the cylinder during
disengagement opens. When the valve is open the fluid is
able to pass freely from the slave cylinder to the reservoir.
