DISASSEMBLY
1. REMOVE FIELD FRAME AND ARMATURE
(a) Remove the nut, and disconnect the lead wire from the
magnetic switch terminal.
Torque: 5.9 N´m (60 kgf´cm, 52 in.´lbf)
(b) Remove the 2 through bolts.
Torque: 9.3 N´m (95 kgf´cm, 82 in.´lbf)
(c) Pull out the field frame together with the armature from the
magnetic switch assembly.
NOTICE:
At the time of assembly, align the protrusion of the field
frame with the groove of the magnetic switch.
(d) Remove the O±ring from the field frame.
HINT:
At the time of assembly, use a new O±ring.
2. REMOVE STARTER HOUSING, CLUTCH ASSEMBLY
AND GEAR
(a) Remove the 2 screws.
Torque: 9.3 N´m (95 kgf´cm, 82 in.´lbf)

INSPECTION
1. INSPECT COMMUTATOR FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
segments of the commutator.
If there is no continuity between any segment, replace the ar-
mature.
2. INSPECT COMMUTATOR FOR GROUND
Using an ohmmeter, check that there is no continuity between
the commutator and armature coil core.
If there is continuity, replace the armature.
3. INSPECT COMMUTATOR FOR DIRTY AND BURNT
SURFACE
If the surface is dirty or burnt, correct it with sandpaper (No.400)
or on a lathe.
4. INSPECT COMMUTATOR CIRCLE RUNOUT
(a) Place the commutator on V±blocks.
(b) Using a dial indicator, measure the circle runout.
Maximum circle runout:
0.05 mm (0.0020 in.)
If the circle runout is greater than maximum, correct it on a lathe.
5. INSPECT COMMUTATOR DIAMETER
Using vernier calipers, measure the commutator diameter.
Standard diameter:
35.0 mm (1.378 in.)
Minimum diameter:
34.0 mm (1.339 in.)
If the diameter is less than minimum, replace the armature.
6. INSPECT UNDERCUT DEPTH
Check that the undercut depth is clean and free of foreign mate-
rials. Smooth out the edge.
Standard undercut depth:
0.7 mm (0.028 in.)
Minimum undercut depth:
0.2 mm (0.008 in.)
If the undercut depth is less than minimum, correct it with a
hacksaw blade.
