“ BAT” term inal (1) and insulator (36).
“ BAT” term inal nut (20).
Capacitor (18) in the end frame.
• Retain with a screw.
Capacitor lead to the rectifier bridge (17) with a screw.
Regulator (16).
Brushes (38) in the brush holder (13).
• Retract the brushes in the holder.
• Retain the retracted brushes with a toothpick
(figure 16).
• Be sure that the toothpick extends through the
end fram e when the brush holder is in place in
the end fram e. After the rotor and drive end
fram e are installed, the toothpick will be pulled
out, allowing the brushes to contact the slip
rings.
Brush holder with retracted brushes.
Diode trio (15).
Resistor (14).
Retaining screws.
— Insulated screws are located at the brush clip
and the diode trio connecting strap.
— G rounded screw is located on the resistor
mount.
Stator (41) to the end frame, aligning the three stator
leads to the three rectifier bridge terminals.
Three term inal nuts. Tighten the nuts securely.

Bearing (32).
• Support the end frame.
• Position the bearing with the sealed end toward
the outside of the generator.
• Press the bearing into the bore using a metal
tube against the bearing outer race.
• Fill the cavity between the retainer plate and the

“ Lubrication” later in this section.
• If the bearing is sealed on both sides, do not add
lubricant.
Bearing retainer (37).

removed.
5. Rotor (42) through the rear collar and the bearing in
the drive end frame.
6. Front collar (34).
7. Fan (44).
8. Pulley (43).
9. Wave washer (23).
10. Pulley nut (22).
• Clam p the rotor in a vise only tight enough to
torque the nut.
Tighten
Pulley nut to 68 N-m (50 ft. lbs.).
