assembly to the lower portion of the support
plate.
The inner assembly of the slave cylinder
is made up of a coil spring, cup filler,
rubber cup and a piston. The piston moves

bushes, it is positioned by
a fixing screw, the shank of which locates
the reduced diameter portion of the shaft.
A short coil spring is placed between the
shaft lever and the bell housing which
steadies the shaft and prevents rattle.
Mounted on the shaft is the release bearing
operating fork, being secured thereto by
a tapered pin, the shank of which passes
into the shaft, whilst its head is locked to
the fork by a short length of wire.
The shaft is lubricated by grease nipples
and over-lubrication must be avoided
(see page 4).

THE RELEASE BEARING
This is a ball bearing housed in a cover. A
sleeve pressed into the inner race of this
bearing, is grooved externally to accom-
modate the pins of the clutch operating
fork mounted on its shaft in the bell
housing of the gearbox. The sleeve, pressed
into the bearing, moves on an extension of
the front gearbox cover which ensures its
correct angular engagement with the three
release levers.
The ball bearing is grease packed during its
manufacture and does not require
re-greasing.
