create dust by sanding or by cleaning
clutch parts with a dry brush or with
compressed air. (A water dampened cloth

SERVICE ADJUSTMENT PROCEDURES
CLUTCH PEDAL INSPECTION AND ADJUSTMY’,
1.Measure the clutch pedal height (from the face of the pedalpad to the
firewall) and the clutch pedal clevis pin play
(measured at the face of the pedal pad.)
Standard value (A): 176.0-181.0 mm (6.93-7.13 in.)
Standard value (B): l-3 mm (.04-.12 in.)
2.If either the clutch pedal height or the clutch pedal clevis
pin play are not within the standard value range, adjust as
follows
:(1) For vehicles without auto-cruise control system, turn
and adjust the bolt so that the pedal height is the
standard value, and then secure by tightening the lock
nut.Vehicles with auto-cruise control system, disconnect
the clutch switch connector and turn the switch for
standard clutch pedal height. Then lock with the lock
nut.
NOTE
When the pedal height is lower than the standard value,
loosen the bolt or clutch switch, and then turn the pushrod to make the adjustment. After making the adjust-
ment, tighten the bolt or clutch switch to reach the
pedal stopper, and then lock with the lock nut.
(2) Turn the push rod to adjust the clutch pedal clevis pin
play to agree with the standard value and then secure
the push rod with the lock nut.
CautionWhen adjusting the
pedal height or the clutch pedal
clevis pin play, be careful not to push the push rodtoward the master
cylinder.3. Check to be sure that the interlock switch is as shown in
the illustration when the clutch pedal is depressed its full
stroke
[151 mm (6.0 in.)]. If necessary, loosen the lock nut
and adjust.
4.After completing the adjustments, confirm that the clutch
pedal free play (measured at the face of the pedal pad)
and the distance between the clutch pedal (the face of the
pedal pad) and the
firewall when the clutch is disengaged
are within the standard value ranges.
Standard value (C):6-13 mm (.24-.51 in.)
Standard value (D):55 mm (2.2 in.) or more

6-6CLUTCH - Service Adjustment Procedures
5.If the clutch pedal free play and the distance between the
clutch pedal and the firewall when the clutch is disengageddo not agree with the standard values, it is probably the
A
result of either air in the hydraulic system or a faulty master2
cylinder or clutch. Bleed the air, or disassemble and inspectthe master cylinder or clutch.
BLEEDINGWhenever the clutch tube, the clutch hose, and/or the clutch
master cylinder have been removed, or if the clutch pedal is
spongy, bleed the system.
Caution
Use the specified fluid. Avoid using a mixture of the
specified fluid and other fluid.
Specified fluid: MOPAR Brake Fluid/Conforming to DOT3
