ground clearance MITSUBISHI MONTERO 1991 Service Manual

Removal
1) Remove shaft nut while holding armature plate with clutch
disk wrench. Install clutch disk puller and remove clutch plate.
Remove snap ring from center of clutch pulley.
2) Use a universal gear puller to remove clutch pulley. See
Fig. 3 .Remove screw securing clutch coil ground lead. Use puller to
remove clutch coil.
Installation
1) To install clutch coil, reverse removal procedure.
Carefully press clutch coil into place. Ensure that coil lead and
connector are positioned on same side as removed coil.
2) Install a NEW clutch pulley snap ring, being careful not
to damage shaft seal. Press clutch plate into place. Install shaft nut
and torque to 0.9-1.4 INCH lbs. (0.10-.12 N.m).
3) Use a feeler gauge to check clutch plate-to-pulley
clearance. Clearance should be .012-.024" (0.3-0.6 mm). If clearance
is too large, remove shaft nut and again press in clutch plate. If
clearance is too small, increase gap by pulling up clutch plate. Do
not remove shaft nut.

brake pedal to center shoes, and check pedal travel. Rotate brake drum
to verify free movement.
STOPLIGHT SWITCH
Loosen lock nut, and adjust switch-to-pedal arm clearance to
.02-.04" (.5-1.0 mm). Tighten lock nut. DO NOT depress master cylinder
push rod during stoplight switch adjustment.
TESTING
POWER BRAKE UNIT
Check Valve Inspection
Remove vacuum hose from power brake unit. Remove check valve
from hose (if possible). Using a vacuum pump, ensure airflow is in
direction of intake manifold only.
System Check
1) Run engine for 2 minutes, and shut it off. Depress brake
pedal several times with normal pressure. If pedal height gradually
becomes higher with successive applications, power brake unit is okay.
If pedal height remains steady, power brake unit is faulty.
2) With engine stopped, depress brake pedal repeatedly until
it's height no longer falls. Hold brake pedal down, and start engine.
If pedal moves downward slightly, power brake unit is okay. If pedal
height does not change, power brake unit is faulty.
3) With engine running, press and hold brake pedal and shut
off engine. Hold brake pedal for 30 seconds. Brake pedal height should
not change. If pedal height falls, power brake unit is faulty.
LOAD-SENSING PROPORTIONING VALVE (LSPV) (PICKUP & RAM-50)
1) Before diagnosing Load-Sensing Proportioning Valve (LSPV)\
,
ensure all other brake components are operating properly. When all
other brake system components are determined to be okay, perform LSPV
test beginning with next step.
2) Ensure unladen vehicle is on level ground. Ensure lever is
not contacting stopper bolt. See Fig. 1.
3) When lever is pushed toward valve, distance from LSPV
lever hole and support hole must be 6.97-7.09 in. (177-180 mm). If
measured distance is not within specification, loosen support bolt.
Adjust support until measured distance is within specification.
4) After measured distance is within specification, connect
pressure gauges to input and output ports of LSPV. See Fig. 4. Bleed
brake system. See BLEEDING BRAKE SYSTEM .

ROCKER ARMS & ASSEMBLIES
Rocker Studs
Rocker studs are either threaded or pressed in place.
Threaded studs are removed by locking 2 nuts on the stud. Unscrew the
stud by turning the jam nut. Coat the stud threads with Loctite and
install. Tighten to specification.
Pressed in stud can be removed using a stud puller. Ream the
stud bore to proper specification and press in a new oversize stud.
Pressed in studs are often replaced by cutting threads in the stud
bore to accept a threaded stud.
Rocker Arms & Shafts
Mark rocker arms for location. Remove rocker arm retaining
bolts. Remove rocker arms. Inspect rocker arms, shafts, bushings and
pivot balls (if equipped) for excessive wear. Inspect rocker arms
for wear in valve stem contact area. Measure rocker arm bushing I.D.
Replace bushings if excessively worn.
The rocker arm valve stem contact point can be reground,
using special fixture for valve grinding machine. Remove minimum
amount of material as possible. Ensure all oil passages are clear.
Install rocker arms in original locations. Ensure rocker arm is
properly seated in push rod. Tighten bolts to specification. Adjust
valves if required. See VALVE ADJUSTMENT in this article.
Pushrods
Remove rocker arms. Mark push rods for location. Remove push
rods. Push rods can be steel or aluminum, solid or hollow. Hollow
pushrods must be internally cleaned to ensure oil passage to the
rocker arms is cleaned. Check the pushrod for damage, such as loose
ends on steel tipped aluminum types.
Check push rod for straightness. Roll push rod on a flat
surface. Using feeler gauge, check clearance at center. Replace push
rod if bent. The push rod can also be supported at each end and
rotated. A dial indicator is used to detect bends in the push rod.
Lubricate ends of push rod and install push rod in original
location. Ensure push rod is properly seated in lifter. Install rocker
arm. Tighten bolts to specification. Adjust valves if required. See
VALVE ADJUSTMENT in this article.
LIFTERS
Hydraulic Lifters
Before replacing a hydraulic lifter for noisy operation,
ensure noise is not caused by worn rocker arms or valve tips.
Hydraulic lifter assemblies must be installed in original locations.
Remove the rocker arm assembly and push rod. Mark components for
location. Some applications require intake manifold, or lifter cover
removal. Remove lifter retainer plate (if used). To remove lifters,
use a hydraulic lifter remover or magnet. Different type lifters are
used. See Fig. 13.

overrunning clutch, armature assembly, solenoid assembly or field
coils due to possible damage. Inspect all parts for damage or wear and
replace as required.
BENCH TESTS
Brushes & Springs
Check brush spring tension using a spring scale. Check brush
contact surface condition and brush length. Check lead clip and wire
connections and condition of brush holders. Replace as required. See
Brush Spring Tension and Minimum Brush Length Charts.

Armature
Check external condition of armature for scoring or other
damage. Measure shaft distortion with dial indicator. Replace armature
if shaft distortion exceeds .004" (.10 mm).
Commutator
1) Inspect commutator for roughness, grooves, burns or
pitting. Sand lightly with 500 grit sandpaper if necessary. Check
commutator for out-of-round and mica insulators undercut to a depth of
.020-.031" (.5-.8 mm).
2) If necessary, commutator may be turned less than .04" (1
mm) from original size and mica undercut. Replace if excessively worn.
Field Coil
1) Check field coil continuity by connecting test probe of
circuit tester or an ohmmeter to the field coil positive terminal and
brush holder. If circuit is open, replace field coil.
2) Check for grounding of field coils by placing one probe of
circuit tester on starter housing and other probe to field coil
positive terminal. If little or no resistance, field coil is grounded
and must be replaced.
Overrunning Clutch Assembly
1) Inspect pinion assembly and sleeve. Sleeve should slide
freely on armature shaft and spline. If damage or resistance is noted,
replace assembly.
2) Check pinion and flywheel teeth for excessive rubbing or
damaged teeth. Replace as required.
