CLUTCH
1998 Mitsubishi Montero
1997-98 CLUTCHES
Mitsubishi RWD
Montero, Montero Sport
DESCRIPTION
Clutch system uses diaphragm spring, single-disc type
clutches. Clutch is hydraulically operated.
ADJUSTMENTS
CLUTCH PEDAL FREE PLAY
1) Depress clutch pedal by hand until resistance is felt.
Measure clutch pedal free play. See CLUTCH PEDAL SPECIFICATIONS table.
See Fig. 1 .
2) If pedal free play needs to be adjusted, loosen lock nut
on clutch master cylinder push rod and rotate push rod to obtain
correct free play. Tighten lock nut. See Fig. 1. If depressed free
play cannot be adjusted, bleed system and inspect hydraulic and clutch
components.
CLUTCH PEDAL HEIGHT
1) Measure distance between face of clutch pedal and floor
board. See CLUTCH PEDAL SPECIFICATIONS table. See Fig. 1. To adjust
pedal height, disconnect clutch switch connector (if equipped).
2) Loosen master cylinder push rod lock nut. Rotate stopper,
clutch switch or clutch master cylinder push rod until correct pedal
height is obtained.

Fig. 1: Measuring Pedal Free Play & Height (Typical)
Courtesy of Mitsubishi Motor Sales of America.
CLUTCH PEDAL INTERLOCK SWITCH
1) Check and adjust pedal height and free play. See
CLUTCH PEDAL HEIGHT and
CLUTCH PEDAL FREE PLAY . See Fig. 1. Measure clutch pedal full stroke.
Full stroke should be 5.72" (145 mm). If full stroke is out of
tolerance, adjust stroke by turning clutch master cylinder push rod.
See Fig. 2 .
2) Measure clearance "A" with clutch pedal fully depressed
(full stroke). See Fig. 2. Clearance "A" should be .177-.217" (4.5-5.5
mm). If clearance is out of tolerance, adjust by loosening interlock
switch lock nut and turning interlock switch in appropriate direction.
When clearance "A" is correct, tighten lock nut.

TESTING
CLUTCH PEDAL DEPRESSED HEIGHT
Depress clutch pedal to floor. Measure distance between face
of clutch pedal and floor board. If depressed pedal height is not as

specified, bleed system and inspect hydraulic and clutch components.
See CLUTCH PEDAL SPECIFICATIONS table.
CLUTCH PEDAL INTERLOCK SWITCH
1) Place transmission in Neutral and apply parking brake.
Turn ignition switch to START position with clutch pedal not
depressed. Engine should not crank. If engine cranks, adjust or
replace interlock switch.
2) Disconnect interlock switch connector. Interlock switch
connector is located at clutch pedal. Depress and release interlock
switch. Using ohmmeter, check continuity between interlock switch
terminals. If continuity exists with interlock switch depressed and
does not exist with switch released, switch is okay. Adjust or replace
as necessary.
REMOVAL & INSTALLATION
CLUTCH ASSEMBLY
Removal (2WD Models)
1) Disconnect negative battery cable. Remove shift knob, dust
cover retaining plate, gaskets, stopper plate and control lever
assembly. Raise and support vehicle.
2) Remove front exhaust pipe. Drain transmission fluid. Index
mark drive shaft flange and remove drive shaft.
3) Disconnect back-up light switch connector, speedometer
cable connection and exhaust pipe mounting bracket. Remove lower
bellhousing cover. Disconnect clutch cable from clutch lever.
4) Support transmission with jack. Remove rear engine mount
nuts and bolts from transmission. Remove crossmember with rear engine
mount. Remove remaining bellhousing bolts, move transmission toward
rear and lower from vehicle.
5) If reusing pressure plate, index mark pressure plate to
flywheel for installation reference. Install a clutch alignment tool
to prevent pressure plate and clutch disc from dropping. Loosen
pressure plate bolts gradually in a crisscross pattern to avoid
warping pressure plate flange during removal. Remove pressure plate
and clutch disc. See Fig. 3.
Inspection
1) Check release bearing and release fork for damage or wear.
DO NOT clean release bearing assembly in solvent.
2) Inspect pressure plate surface for wear, cracks, and/or
discoloration. Measure diaphragm spring ends for wear and uneven
height. Replace assembly if height difference between fingers exceeds
.02" (.5 mm).
3) Check facing of clutch disc for loose rivets, uneven
contact, deterioration, seizure or oil saturation. Measure distance
from clutch disc surface to head of rivet. Replace clutch disc if
distance is less than .012" (.30 mm). Replace worn or defective
components as necessary. See Fig. 4.
CAUTION: Install clutch disc with manufacturer's stamp mark (located
near hub of clutch disc) toward pressure plate.
Installation
1) Using a clutch alignment tool, install pressure plate and
clutch disc. If reusing pressure plate, ensure index marks are
aligned. Tighten bolts evenly in a crisscross pattern to
specification. See TORQUE SPECIFICATIONS . See Fig. 3.
2) Clean release bearing sliding surface. DO NOT clean
