Disassembly
DANGER:
Before servicing any Generac®
equipment, always remove the spark plug lead.
Unintentional ignition can cause severe personal
injury.
Removing The Generator Access Cover
• Remove the four retaining screws that secure the
access cover to the rear bearing carrier
Figure 4.2.
This exposes the components described in
Figure 4.3.
They include:
• The Brush Assembly and its mounting hardware.
• The Brush wires and terminals.
• The Rotor Bearing.
A visual inspection of this area can reveal both mechanical
problems as well as problems with wiring connections.
Before continuing with the disassembly process, visually
inspect for the following:
• Evidence of bearing failure. (Very fine metallic “dust”
that generally accumulates around the bearing carrier
assembly.)
• Loose or broken connector at all wire ends and
insertion points into plug assemblies.
• Vibration damage (chafing) to any components due to
rubbing or other contact friction.
• Burned varnish or lacing on stator winding.
