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.
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.
