4. INSPECT UNDERCUT DEPTH OF SEGMENT I-.-.v-.
.
Check that the undercut depth is clean and free of foreig,
materials. Smooth out the edge.
Standard undercut depth:
Minimum undercut depth: 0.6 mm (0.024 in.)
0.2 mm (0.008 in.)
If the undercut depth is less than minimum, correct it
with
a
hacksaw blade.
Field Frame (Field Coil)
1.
INSPECT FIELD COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity be-
tween the lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
2.
INSPECT THAT FIELD COIL IS NOT GROUNDED
Using an ohmmeter, check that there is no continuity be-
tween the field coil end and field frame.
If there is continuity, repair or replace the field frame.
Brushes
INSPECT BRUSH LENGTH
Using vernier calipers, measure the brush length.
Standard length:
1 .O kW type 13.5 mm (0.531 in.)
1.4 kW type 15.5 mm (0.610 in.)
Minimum length:
1.0 kW type 8.5 mm (0.335 in.)
1.4 kW type 10.0 mm (0.394 in.)
If the length is less than minimum, replace the brush
holder and field frame.

STOO6:
Brush Springs.
INSPECT BRUSH SPRING LOAD
Take the pull scale reading the instant the brush spring
separates from the brush.
Standard installed load:
1.785 - 2.415 kg (3.9 - 5.3 lb, 18 - 24 N) -
Minimum installed load:
1.2 kg (2.8 lb, 12 N)
If the installed load is less than minimum, replace the
brush springs.
Brush Holder
INSPECT INSULATION OF BRUSH HOLDER
Using an ohmmeter, check that there is no continuity be-
tween the positive (+I and negative (-1 brush holders.
If there is continuity, repair or replace the brush holder.
Clutch and Gears
1. INSPECT GEAR TEETH
Check the gear teeth on the pinion gear, idler gear and
clutch assembly for wear or damage.
If damaged, replace the gear or clutch assembly.
If damaged, also check the flywheel ring gear for wear or
damage.
2. INSPECT CLUTCH
Rotate the clutch pinion gear clockwise and check that it
turns freely. Try to rotate the clutch pinion gear coun-
terclockwise and check that it locks.
If necessary, replace the clutch assembly.

(a)
Using SST, remove the bearing.

PERFORM PULL-IN COIL OPEN CIRCUIT TEST
Using an ohmmeter, check that there is continuity be-
tween terminal 50 and C.
If there is no continuity, replace the magnetic switch
assembly.
2.
PERFORM HOLD-IN COIL OPEN CIRCUIT TEST
Using an ohmmeter, check that there is continuity be-
tween terminal 50 and the switch body.
If there is no continuity, replace the magnetic switch
assembly.

NOTE: Use high-temperature grease to lubricate the
bearings and gears when assembling the starter.
PLACE ARMATURE INTO FIELD FRAME
_
Apply grease to the armature bearings and insert the
armature into the field frame.
INSTALL BRUSH HOLDER
(a) Using a screwdriver, hold the brush spring back, and
connect the brush into the brush holder. Connect the
four brushes.
NOTE: Check that the positive (+I lead wires are not
grounded.
(b) P’x; a new O-ring on the field frame.ll.4 kW type
(c) Install the end cover to the field frame.
INSERT STEEL BALL INTO CLUTCH SHAFT HOLE
(a) Apply grease to the steel ball.
(b)
Insert the steel ball into the clutch shaft hole.
INSTALL GEARS AND CLUTCH ASSEMBLY
(1.0 kW type)
(a) Apply grease to the gear and clutch assembly.
(b)
Place the clutch assembly, idler gear and bearing in
the starter housing.
(1.4 kW type)
(a) Apply grease to the gears and clutch assembly.
(b) Place the clutch assembly, idler gear, bearing and
pinion gear in the starter housing.

PERFORMANCE TEST OF STARTER
CAUTION:
These tests must be performed within 3
to 5 seconds to avoid burning out the coil.
PERFORM PULL-IN TEST
(a) Disconnect the field coil lead wire from terminal C.
(b) Connect the battery to the magnetic switch as
shown. Check that the clutch pinion gear moves out-
ward.
If the clutch pinion gear does not move, replace the mag-
netic switch assembly.
PERFORM HOLD-IN TEST
While connected as above with the clutch pinion gear out,
disconnect the negative (-1 lead from terminal C. Check
that the pinion gear remains out.
If the clutch pinion gear returns inward, replace the mag-
netic switch assembly.
INSPECT CLUTCH PINION GEAR RETURN
Disconnect the negative I-1 lead from the switch body.
Check that the clutch pinion gear returns inward.
If the clutch pinion gear does not return, replace the mag-
netic switch assembly.
PERFORM NO-LOAD PERFORMANCE TEST
(a) Connect the battery and ammeter to the starter as
shown.
(b) Check that the starter rotates smoothly and steadily
with the pinion gear moving out. Check that the
ammeter reads the specified current.
Specified current: 90A or less at 11.5 V
