Inspection After Assembly
Use a vernier caliper to measure the pinion shaft thrust
play.
The pinion shaft thrust play is equal to the pinion shaft
end and pinion stopper clearance.
Pinion Shaft Thrust Play mm (in)
0.1 – 2.0 (0.004 – 0.078)

Magnetic Switch
The following tests must be performed with the starter
motor fully assembled.
The yoke lead wire must be disconnected from the “M”
terminal.
To prevent coil burning, complete each test as quickl
y
as possible (within three to five seconds).

Temporarily connect the solenoid switch between the
clutch and the housing and run the following test.
Complete each test within three to five seconds.
1. Pull-in Test
Connect the battery negative terminal with the solenoid switch body and the M terminal. W hen
current is applied to the S terminal from the batter
y
positive terminal, the pinion should flutter.



RTW 46DSH004601
2. Hold-in Maintenance Test
Disconnect the lead at the M terminal. The pinion should continue to flutter.



RTW 46DSH005901
3. Return Test
Disconnect the battery positive lead at the S terminal.
The pinion should return to its home position.

Inspection and Repair
Make the necessary adjustments, repairs, and part
replacement if excessive wear of damage is discovered
during inspection.
Visual Check
Check the main fuses and glow indicator for damage.
Replace the part(s) if required.
Glow Relay
The glow relay is located in the relay box the engine
compartment.
Use an ohmmeter to measure the resistance between
terminals No.2 and No.3.
If the measured value is outside the specified range, the
glow relay must be replaced.
