6 - 22 CLUTCH
MASTER CYLINDER - LHD
DESCRIPTION
CAUTION: The clutch master cylinder pushrod
adjustment must not be used to change pedal free-
play or pedal height. Using the adjustable pushrod
for these reasons will result in premature clutch
wear or system over/undertravel.
NOTE: Vehicles equipped with a 1.6/2.0/2.4L (Non-
Turbo) engine have one-piece master cylinder
assemblies. If the master cylinder requires replace-
ment, the master AND slave cylinders must be
replaced with a two-piece system.
The clutch master cylinder mounts to the dash
panel (Fig. 33) and consists of a push rod (adjustable
on LHD models), a piston and cylinder housing, an
integral fluid reservoir, and an interconnecting
hydraulic tube (Fig. 34). 1.6/2.0/2.4L (Non-Turbo)-
equipped models have a master cylinder which incor-
porates a slave cylinder as well.

OPERATION

The clutch master cylinder (Fig. 33) (Fig. 34) pro-
duces the hydraulic pressure necessary to disengage
the clutch. When the clutch pedal is depressed, the
push rod moves the piston to produce pressure in the
cylinder. This pressure moves fluid through the sys-
tem to the slave cylinder, which in turn operates the
release lever and bearing, disengaging the clutch.

When the clutch pedal is released, pressure is
relieved and the return spring returns the piston to
its original position until the next pedal actuation.

REMOVAL

NOTE: Vehicles equipped with a 1.6/2.0/2.4L (Non-
Turbo) engine have one-piece master/slave cylinder
assemblies. If the master cylinder requires replace-
ment, the master AND slave cylinders must be
replaced with a two-piece "quick-connect" system.
If the slave cylinder requires replacement, the slave
cylinder is serviced separately.
NOTE: Replacement master cylinder assemblies
come pre-filled with fluid. No fluid service or sys-
tem bleeding should be required, unless the
hydraulic system has lost an excessive amount of
fluid and has ingested air into the master or slave
cylinder assembly.
