DESCRIPTION & OPERATION
Starter is a conventional 12-volt, 4-pole brush-type motor,
with direct or gear reduction drive. Starter-mounted solenoid shifts
overrunning clutch and pinion into flywheel when starter is energized.

BENCH TESTING
* PLEASE READ THIS FIRST *
CAUTION: Perform tests in less than 10 seconds to prevent damage to
coil.
NO-LOAD TEST
1) Install starter in soft-jawed vise. Connect starter in
series with a fully-charged 12-volt battery. Connect a 100-amp ammeter
and carbon pile rheostat in series with positive battery post and
starter motor terminal. See Fig. 2.
2) Install voltmeter across starter motor. Adjust carbon pile
rheostat to full resistance. Connect cable from starter motor body to
negative battery terminal. Adjust carbon pile rheostat to proper test
voltage. Ensure maximum amperage is as specified and starter rotates
Page 1084 of 1501
smoothly. See STARTER NO-LOAD TEST SPECIFICATIONS table.

PULL-IN COIL TEST
1) Disconnect field coil wire from terminal "M" at starter
solenoid. See Fig. 3. Connect jumper wire between positive battery
terminal of 12-volt battery and terminal "S" of solenoid.
2) Connect a second jumper wire from negative battery
terminal and touch terminal "M" of starter solenoid. If solenoid
plunger moves inward, solenoid is good. If solenoid plunger does not
move inward, replace solenoid.

HOLD-IN COIL TEST
1) Disconnect field coil wire from terminal "M" at starter
solenoid. See Fig. 3. Connect jumper wire between positive battery
terminal of 12-volt battery and terminal "S" of starter solenoid.
2) Connect a second jumper wire from negative battery
terminal and touch starter case. If solenoid plunger is pulled in,
hold-in coil is good. If solenoid plunger is not pulled in, replace
solenoid.
PINION RETURN TEST
1) Disconnect field coil wire from terminal "M" at starter
solenoid. See Fig. 3. Connect jumper wire between positive battery
terminal of 12-volt battery and terminal "M" of starter solenoid.
2) Connect a second jumper wire from negative battery
terminal and touch starter case. Pull pinion outward and release it.
Replace solenoid if pinion remains out.
PINION GAP MEASUREMENT
1) Disconnect field coil wire from terminal "M" at starter
solenoid. See Fig. 3. Connect jumper wire between positive battery
terminal of 12-volt battery and terminal "S" of starter solenoid.
2) Connect a second jumper wire from negative battery
terminal and touch terminal "M" of starter solenoid. Using a feeler
gauge, measure clearance between pinion and stopper. See Fig. 4.
3) Clearance should be within specification. See
STARTER SPECIFICATIONS table. Adjust clearance by adding or removing
gaskets between solenoid and front housing.

PINION TEST
While holding pinion housing, rotate pinion. Pinion should
rotate smoothly in clockwise direction only. Inspect pinion and ring
gear for wear or burrs. If pinion does not rotate as specified or
damage is found, replace pinion.
Page 1087 of 1501
ARMATURE TEST
Ensure armature is not grounded. Place armature in growler.
Hold a thin steel blade parallel and just above armature while slowly
rotating armature in growler. A shorted armature will cause blade to
vibrate and be attracted to core. Using an ohmmeter, check continuity
between armature coil cores and commutator segments (small diameter
end of armature). Continuity should not exist. Check for continuity
between segments. Continuity should exist. Replace armature as
necessary.
BRUSH HOLDER TEST
Using an ohmmeter, check continuity between brush holder
plate and brush holder. Continuity should not exist. Replace brush
holder as necessary.
REMOVAL & INSTALLATION
NOTE: On Montero with A/T, it may be necessary to disconnect
transmission oil cooler line for starter removal.
Removal & Installation
Disconnect negative battery cable. If necessary, raise
vehicle on hoist. Remove starter mounting bolts and starter. To
install, reverse removal procedure.
OVERHAUL
Check commutator for out-of-round and proper amount of
undercut. Replace or repair armature if not within specification. See
STARTER SPECIFICATIONS table. Ensure brushes are not worn beyond wear
line (outer line closest to commutator contact surface). Check pinion
gap. See PINION GAP MEASUREMENT under BENCH TESTING. See Figs. 5 and
6.
