Three-Phase Generator

Removing and installing three-phase generator - GT3

Removal

1. Disconnect the battery and cover terminal or battery. Undo the fastening screw for the air cleaner housing and the hose clamp on the air flow sensor.




2. Disconnect the electrical plug connection on the air flow sensor and remove the complete air cleaner assembly.

3. Relieve the drive belt on the tensioning pulley and remove the belt.

4. Remove the deflection roller under the three-phase generator.

5. Disconnect the cable lug of the B+ lead to the three-phase generator at the B+ disconnection point.




6. Undo left fastening screw (in direction of travel) and unscrew.

7. Undo right fastening screw by three turns. A gentle tap on the fastening screw loosens the threaded bushing in the three-phase generator arm (use aluminium mandrel). Unscrew fastening screw.

8. Remove three-phase generator and carefully pull a little to the rear. Press the plug connection towards the three-phase generator housing, release and pull off. Pull out three-phase generator to the rear.

9. Undo B+ lead on the three-phase generator.


Installation

1. Fasten B+ lead and install three-phase generator.

2. Install deflection roller and fit drive belt.

Tightening torques:

Hexagon nut a/f 24, M16 x 1.5, 65 ± 5 Nm (48 ± 3.5 ftlb.)

Hexagon-head bolts, M1O, 46 Nm (34 ftlb.)

Hexagon nut a/f 13, M8, 15 Nm (11 ftlb.)

Deflection roller a/f 17, M10, 46 Nm (34 ftlb.)

3. Install air flow sensor with air cleaner assembly and connect battery. Perform a function test.


Undoing and tightening the belt pulley

Note

The belt pulley can be undone and tightened using a standard commercially available tool.
Tools: double offset ring wrench a/f 24, screwdriver insert for screw with internal serrations a/f 10, cross handle and torque wrench.

The hexagon nut a/f 24 must be countered with the ring wrench during tightening. The shaft is tightened to the prescribed tightening torque of 65 ± 5 Nm (48 ± 3.5 ftlb.) using the screwdriver insert and the torque wrench.
