3. Cruise Control System
3. STATOR
1) Continuity test
Inspect stator coil for continuity between each end
of the lead wires. If there is no continuity between
individual lead wires, the lead wire is broken, and
so replace stator assembly.
S6M0408
2) Insulation test
Inspect stator coil for continuity between stator
core and each end of the lead wire. If there is
continuity, the stator coil is grounded, and so
replace stator assembly.
G6M0079
4. BRUSH
1) Measure the length of each brush. If wear
exceeds the service limit, replace the brush. Each
brush has the service limit mark (A) on it.
Brush length:
Standard
18.5 mm (0.728 in)
Service limit
5.0 mm (0.197 in)
H6M0499C
2) Checking brush spring for proper pressure
Using a spring pressure indicator, push the brush
into the brush holder until its tip protrudes 2 mm
(0.08 in). Then measure the pressure of the brush
spring. If the pressure is less than 2.648 N (270 g,
9.52 oz), replace the brush spring with a new one.
The new spring must have a pressure of 4.609 to
5.786 N (470 to 590 g, 16.58 to 20.81 oz).

5. BEARING (FRONT SIDE)
1) Check front ball bearing. If resistance is felt
while rotating, or if abnormal noise is heard,
replace the ball bearing.
2) Replacing front bearing
(1) Remove front bearing retainer.
(2) Closely install a fit tool on the bearing inner
race. Press the bearing down out of front
bracket with a hand press or vise. A socket
wrench can serve as the tool.
