6D3–25

STARTING AND CHARGING SYSTEM (6VD1 3.2L)

1. Using a press with a socket wrench attached,

reassemble rotor and rear end cover assembly in the
front cover.

066RS022

2. Install pulley on the rotor.

Secure the pulley directly in the vise between two
copper plates, and tighten nut to the specified torque.

Torque: 111 N·m (82 lb ft)

066RS010

Bench Test

Conduct a bench test of the generator.

066RS023

Preparation

Remove generator from the vehicle (see “Generator
removal”).

1. Secure generator to the bench test equipment and

connect wires.
Terminal “IG” for energization
Terminal “L” for neutral (warning lamp)
Terminal “B” for output

2. Conduct the generator characteristic test.

Characteristics of generator are shown in illustration.
Repair or replace the generator if its outputs are
abnormal.
