- 2.3 N*m{ 23 kgf*cm, 20 in.*lbf}
2. INSTALL GENERATOR ROTOR ASSEMBLY |
Place the drive end frame on the clutch pulley.

Install the rotor assembly to the drive end frame.

Place a new generator washer on the generator rotor.
3. INSTALL GENERATOR COIL ASSEMBLY |

Using SST and a press, press in the generator coil assembly to the drive end frame.
- SST
- 09612-70100(09612-07240)

7. INSTALL CLUTCH PULLEY |
Temporarily install the clutch pulley onto the rotor shaft.

Set SST (A) and (B).
- SST
- 09820-63020

Clamp SST (A) in a vise.
Place the rotor shaft end into SST (A).

Fit SST (B) to the clutch pulley.

Tighten the pulley by turning SST (B) in the direction shown in the illustration.
- Torque:
- 111 N*m{ 1,127 kgf*cm, 81 ft.*lbf}
- NOTICE:
- The torque shown above should be used for tightening without using SST. When the SST is used for tightening, the torque should be calculated based on the length of the SST .
Remove the generator assembly from the SST.
Check that the clutch pulley rotates smoothly.
Install the new clutch pulley cap to the clutch pulley.
