(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

7. INSPECT FIELD COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
lead wire and field coil brush lead.
If there is no continuity, replace the field frame.
8. INSPECT SHUNT COIL FOR OPEN CIRCUIT
Using an ohmmeter, check that there is continuity between the
field coil end and field frame.
If there is no continuity, repair or replace the field frame.
9. INSPECT SHUNT COIL FOR OPEN CIRCUIT
Using an ohmmeter, measure the resistance between shunt
coil terminals (A) and (B).
Resistance: 1.5 to 1.9 W at 20 °C (68 °F)
If the resistance is not as specified, replace the field frame.
10. INSPECT BRUSH LENGTH
Using vernier calipers, measure the brush length.
Standard length: 15.0 mm (0.591 in. )
Minimum length: 9.0 mm (0.354 in. )
If the length is less than minimum, replace the brush holder and
field frame.
11. INSPECT BRUSH SPRING LOAD
Using a pull scale, measure the spring load by pulling the spring
from the brush until they are separated.
Standard spring installed load: 21.5 to 27.5 N ( 2.2 to
2.8 kgf, 4.8 to 6.2 lbf )
Minimum installed load: 12.7 N (1.3 kgf, 2.9 lbf )
If the installed load is less than minimum, replace the brush
springs.
