CLUTCH PEDAL POSITION SWITCH
All BR models are equipped with a clutch pedal po­
sition switch (Fig. 7). The switch is in circuit with
the starter relay and is mounted on the clutch mas­
ter cylinder push rod. The switch is actuated by
clutch pedal movement. The clutch pedal must be
fully depressed in order to start the engine.
The position switch is an integral part of the clutch
master cylinder push rod and is not serviced sepa­
rately.
Position switch circuitry is provided at the end of
this section (refer to Figure 10).

CLUTCH HYDRAULIC LINKAGE
The hydraulic linkage consists of a remote reser­
voir, clutch master cylinder, clutch slave cylinder and
interconnecting fluid lines (Fig. 8).
The clutch master cylinder is connected to the
clutch pedal and the slave cylinder is connected to
the clutch release fork. The master cylinder is
mounted on the drivers 3 side of the dash panel adja­
cent to the brake master cylinder.

CLUTCH LINKAGE FLUID
The clutch fluid reservoir, master cylinder, slave
cylinder and fluid lines are prefilled with fluid at the
factory during assembly operations.
The hydraulic system should not require additional
fluid under normal circumstances. In fact, the reser­
voir fluid level will actually increase as normal
clutch wear occurs. For this reason, it is important to
avoid overfilling, or removing fluid from the reser­
voir.
If inspection or diagnosis indicates additional fluid
may be needed, use Mopar brake fluid, or an equiv­
alent meeting SAE and DOT standards J1703 and
DOT 3. Do not use any other type of fluid.
CLUTCH COMPONENT LUBRICATION
Proper clutch component lubrication is important
to satisfactory operation. The correct lubricant and
not overlubricating are equally important. Apply rec­
ommended lubricant sparingly to avoid disc and pres­
sure plate contamination.
Clutch and transmission components requiring lu­
brication are:
• pilot bearing
• release lever pivot ball stud
• release lever contact surfaces
• clutch disc hub splines
• clutch pedal pivot shaft bore
® clutch pedal bushings
• input shaft splines
» input shaft pilot hub
o transmission front bearing retainer slide surface
Do not apply grease to any part of the clutch
cover, disc, or release bearing.
Recommended Lubricants
Use Mopar multi-purpose grease for the clutch
pedal bushings and pivot shaft. Use Mopar high tem­
perature grease (or equivalent) for all other lubrica­
tion requirements. Apply recommended amounts and
do not overlubricate.
GENERAL DIAGNOSIS INFORMATION
Unless the cause of a clutch problem is obvious, a
road test and component inspection will be required
for accurate diagnosis.
A road test will help determine the type of fault
while component inspection will identify the problem
component.
During a road test, drive the vehicle at normal
speeds. Shift the transmission through all gear
ranges and observe clutch action.
If chatter, grab, slip, or improper release is experi­
enced, remove and inspect the clutch components.
However, if the problem is noise or hard shifting, fur­
ther diagnosis is needed. The transmission or an­
other driveline component may actually be at fault.
