24. Through Bolt

Install the through bolts in the rear cover and tighten them
to the specified torque.

Through Bolt Torque N×m (kg×m/lb×ft)

8.1 (0.83/6.00)

065RY00044

25. Lead Wire

Connect the lead wire in the magnetic switch and tighten
the terminal nut to the specified torque.

Lead Wire Terminal Nut Torque N×m (kg×m/lb×ft)

8.6 (0.88/6.40)

RTW46DSH002601 Inspection After Assembly
RTW46DSH005801
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)

6D – 32 ENGINE ELECTRICAL

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 quickly 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. When current is applied to
the S terminal from the battery positive terminal, the pinion
should flutter.

RTW46DSH004601

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

RTW46DSH005901

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

PRE-HEATING SYSTEM

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.

Glow Relay Resistance Ohms

94 - 114

825R300046

GLOW PLUG

Use a circuit tester to test the glow plugs for continuity.

Glow Plug Resistance (Reference) Ohms

Approximately 0.9
