11. Prepare the brushes for endbell removal.
Carefully disconnect the wire harness leads
from the brush block and pull each brush out-
ward from the holder and at the same time in-
sert a piece of wire into the small hole in the
endbell at the bottom of the brush block. See
Figure 9-4. Carefully guide the wire through the
brush block and then release each brush.
Verify that each brush is held off the slip rings
by the wire. Remove the wires from the magne-
to assembly. Loosen the two screws holding
the brush block to the endbell.
CAUTION
The brushes will be damaged
during disassembly if not held off the slip
rings. Make certain wire is in place before
removing the generator endbell. Also the
brush block must be loose so it will clear
the bearing when the endbell is removed.
12. Disconnect the starter bracket from the rear of
the starter. Remove the endbell mounting
screws and place the endbell along side the
front of the genset to eliminate more wire re-
moval.
13. Pull outward on the rotor shaft to remove it. If
the rotor does not come loose from the tapered
engine crankshaft, install a solid round bar
stock 7-7/8 inches (200mm) long by 0.45 inch-
es (11.43 mm) in diameter into the rotor
through bolt hole (Figure 9-5). Thread a
9/16-12 x 1-inch bolt, into the end of the rotor
shaft and slowly tighten the bolt until the rotor
comes loose.
CAUTION
Careless handling of rotor or
stator can damage the insulation on the
windings. Do not allow windings to be
brushed or scraped during removal. Do not
touch the slip rings or corrosion will occur.
14. Wear gloves to protect hands from sharp
edges on the stator assembly. Remove the
wire harness connectors from the stator as-
sembly. Remove the stator mounting screws.
Carefully pull the stator straight out from the
housing. If the stator will not slide out, tap on
generator housing while pulling on the stator to
remove.
