Usage:
start by:
a) remove generator from engine
b) remove control panel
1. Remove the louvers (1) and panel (2) from back of generator frame.
2. Remove the side panels and frame on back of generator. Remove the retainers that hold the bearing in the cover.
3. Use a hoist to put the generator in a vertical position with the hub at the top.
4. Remove the plates (3), shims and the generator fan (4). Keep the plates and shims together for installation.
5. Remove the rotor assembly from the stator with a hoist.
| NOTICE |
|---|
Do not let the rotor make a contact with the stator when it is removed. |
Install Rotor Assembly (Vertical Method)
1. Be sure the stator assembly and rotor assembly are clean.
2. Lift the rotor into position over the stator with a hoist. Slowly lower the rotor into the stator. Be sure the bearing is in position in the cover.
| NOTICE |
|---|
Do not let the rotor make a contact with the stator when it is lowered into the armature. |
3. Put the generator in a horizontal position with a hoist.
4. Put the generator fan over the hub. Install the original amount of shims and plates (1) on the hub.
5. Install retainers (2) for the bearing.
6. Install the frames, covers, louvers, and panels on back of generator.

a. install generator on engine
b. install control panel
Remove Rotor Assembly (Horizontal Method)
start by:
a) remove generator from engine
b) remove control panel
1. Remove plates (1), shims (3), and fan (2) from the front of generator.
2. Install pieces of cardboard or sheet metal (4) between the rotor assembly and the stator assembly. Be sure the pieces are as long as the rotor assembly.
3. Remove the louvers and panels from the back of generator. Remove the bolts that hold the retainers for the bearing. Disconnect wires F1 and F2 from the regulator assembly.
4. Remove the bolts for the cover. Install two guide bolts (5) with 1/2"-13 NC threads, approximately 10 in. (250 mm) long. Connect a hoist to the cover. Push the cover from the bearing with two 3/8"-16 NC forcing bolts. Remove the cover.
| NOTICE |
|---|
Do not damage the stationary exciter field, which is part of the cover, when removing the cover. |
5. Fasten a hoist to the back of shaft.
6. Put a steel pipe (7) on the end of shaft, to the inside of hub.
NOTE: Be sure the pipe is long enough to go through the generator.
7. Remove rotor assembly (6) out the back of generator with a hoist.
| NOTICE |
|---|
Keep the rotor assembly level at all times during removal. This will prevent damage to the armature windings in the generator. |
Install Rotor Assembly (Horizontal Method)
1. Be sure the stator assembly and the rotor assembly are clean.
2. Put a piece of cardboard or sheet metal on the inside of the stator.
3. Put the rotor in position for installation in back of the generator. Put a steel pipe through the stator and on to the front of the shaft, against the hub.
4. Fasten a hoist to the end of rotor (1). Install the rotor. Use the pipe as a support for the other end of the rotor.
| NOTICE |
|---|
Keep the rotor level when it is installed and prevent damage to the stator wiring. |
5. Remove the cardboard or sheet metal from between the rotor and the stator.
6. Install with two guide bolts 1/2"-13 NC threads, 10 in. (250 mm) long, in the back of generator. Install the cover assembly with a hoist. Connect the two field wires F1 and F2 to the regulator assembly.
| NOTICE |
|---|
Do not damage the stationary exciter field which is part of the cover, when the cover is installed. |
7. Install the two retainers (2) for the bearing. Install the louvers and panel in the back of the generator frame.
8. Install the generator fan (4). Install the original amount of shims (3), and plates on the generator hub.
end by:
a) install the generator on engine
b) install control panel
