Section 6 Disassembly/Reassembly
This section provides instructions for the disassembly
and reassembly of the generator set alternator. Before
beginning the generator disassembly or reassembly
procedure, carefully read all safety precautions at the
beginning of this manual.
The engine and generator set may use both American
Standard and metric hardware. Use the correct size
tools to prevent rounding of the bolt heads and nuts.
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (--) lead first
when disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or equipment connected to the set, disable the
generator set as follows: (1) Move the generator set master
switch to the OFF position. (2) Disconnect the power to the
battery charger. (3) Remove the battery cables, negative (--)
lead first. Reconnect the negative (--) lead last when
reconnecting the battery. Follow these precautions to prevent
starting of the generator set by an automatic transfer switch,
remote start/stop switch, or engine start command from a
remote computer.

6.1 Initial Steps
Perform the following steps before disassembling the
generator set.
1. Disconnect AC power to the generator set by
opening the upstream circuit breaker. (AC power is
connected to the generator set for AC-powered
accessories.)
2. Shut off the fuel supply. Disconnect the fuel system
if necessary to tilt the generator set. Ventilate the
area to clear fumes.
3. Allow the generator set and engine to cool.
4. Verify that any hoists or lifting devices used in the
disassembly or reassembly procedure are rated
for the weight of the generator set, which is
approximately 227 kg (500 lb.).
