ENGINE ELECTRICAL 6D – 11

Cooling Fan Belt

1) Hold the generator toward the engine.
2) Install the fan belt to the three pulleys.

(1) Crankshaft pulley
(2) Water pump pulley
(3) Generator pulley

3) Adjust the fan belt tension

(1) Use a bar to pull the generator away from the

engine as far as possible.

(2) Use your hand to apply a pressure of 10 kg (22

lb/98N) to the area of the fan belt indicated by the
arrow in the illustration.
There should be from 8 – 12 mm (0.3 – 0.5 in) of
belt deflection.

4) Tighten the adjusting plate bolts to the specified

torque.

Pulley Nut Torque

± 0.5 (13.7 ± 3.6/18.3 ± 4.9)

5) Reconnect the battery cable to the battery.

Important Operations

1. Vacuum

Pump

1) Loosen the vacuum pump fixing bolts.
2) Support the vacuum pump center plate.
3) Carefully remove the vacuum pump.

2. Cover
3. Brush

1) Remove

the

cover.

2) Remove the brush fixing bolts.
3) Remove the brushes from the brush holder.

4. Through

Bolt

9. Rotor

Assembly

1) Loosen the through bolts.
2) Remove the rotor and front cover assembly from the

stator and rear cover assembly.
Do not allow the stator to separate from the rear
cover.
Take care not to damage the oil seal.

3) Tape the rotor splines to protect them from damage.

5. Pulley

Assembly

1) Carefully clamp the rotor assembly in a vise.
2) Loosen the pulley nut.
3) Remove the pulley and the front cover from the rotor.

13. Front Cover Assembly

1. Remove the front cover bearing retainer screws.
2. Remove

the

bearing.

18. Terminal Nut and Bolt
20. Rear Cover
21. Stator
22. Diode

1) Loosen the terminal nuts and bolts.
2) Remove the insulators and the washers.
3) Remove the stator together with the diodes.
4) Disconnect the stator coil leads between each diode

and the N-terminal by melting the solder connection.
Hold the lead wire between the solder and the diode
with a pair of long nose pliers.
This will prevent heat transfer and resultant damage to
the diode.

25. IC Regulator Assembly

1) Melt away the solder from the IC regulator holder plate

terminal.

2) Remove the IC regulator assembly.

Remove the center plate, rotor and vane in the vacuum
pump.
