1. Remove the unit top and side panels in order to access the generator.
2. Disconnect the battery.
CAUTION
!
Observe proper polarity when installing the battery or connecting a battery charger, the nega-
tive battery terminal must be grounded. Reverse polarity may damage the charging system.
When charging the battery in unit, isolate the battery by disconnecting the negative battery ter-
minal first, then the positive. Once the battery has been charged, connect the positive battery
terminal first, then the negative.
3. Remove the truss assembly center nuts and nut plate.
4. Remove the truss side bolts/washers and spacers (2), and remove the truss.
5. Remove the 3/8” bolt/washer that secures the wire harnesses and fuel lines to the top of the generator,
move the wire harnesses and fuel lines out of the way.
6. Remove the 1/4” bolts/washers (4) that secure the battery charger bracket to the unit frame. This will allow
you to access the cables on the bottom of the battery charger.
7. Mark and disconnect the cables on the battery charger, remove the battery charger assembly from the unit.
8. Remove the bolts/washers (6) that secure the receptacle box to the unit. Wire-tie the receptacle box to the
side of the unit so that the receptacle box is not hanging by the cables.
9. Un-tape the wire harness and cut the wires (7) that connect the receptacle box to the generator. Make sure
to cut the wires on the receptacle box side of the current butt splices.
10. Remove the bolts/washers (2) that secure the generator support plate to the two generator shock mounts.
11. Remove the bolts/washers (3) that secure the lower radiator access panel (on the other side of the unit) in
order to access the engine shock mounts.
12. Back off (about 1”), but do not remove the engine shock mount bolts. This will allow the engine/generator to
be slightly lifted off of the unit frame.
NOTICE
The generator/engine must be slightly lifted off of the unit frame in order to provide enough
clearance for the generator support plate to slide away from the unit frame.
13. Using the lifting lugs on the top of the generator, lift the generator/engine several inches so that the genera-
tor support plate will clear the unit frame allowing the entire generator assembly to be removed.
14. Place several support beams under the engine, and then lower the generator/engine onto the beams. Make
sure that the generator support plate is lifted high enough to allow for the removal of the generator assem-
bly, but not so high that the fan hits the radiator coil.
15. Starting with the lower bolts, remove the bolts/washers (12) that secure the generator to the engine.
NOTICE
Although the generator drive gear and fly wheel adapter plate will normally keep the generator
coupled to the engine, even without the bolts, it is safest to remove the lower generator bolts
first, in case the generator shifts and falls during bolt removal.
16. Lift the generator assembly (generator & support plate) off of the unit frame and lower it onto a stable work
surface.
NOTICE
Inspect the generator drive gear, bolt, and key as they will have to be removed from the old genera-
tor and installed onto the new generator; replace these components if they are worn or damaged.
