(26).
h.
Using overhead lifting device, reposition generator assembly on work table with end bell (31) resting on table.
i.
Using arbor press, press exciter rotor (22) on rotor assembly(18) to shoulder of shaft. Connect F1 + and F2-
Ieads on rotating rectifiers with washers (20) and nuts (19). Torque nuts (20) 23 to 26 in-lbs (2.6 to 2.9 Nm).
Remove tags.
j.
Press bearing (19) onto shaft of rotor assembly (18).
Use care to avoid contact between frame/stator assembly (5) and rotor assembly
(18).
k.
Attach lifting device to rotor assembly (18) and carefully lower rotor assembly(18) into frame/stator assembly
(5). Ensure bearing (19) enters bearing bore in end bell (31).
1.

4-12-6. Installation.
a.
Install flywheel (10, Figure 4–25) to engine crankshaft with bolts (13). Torque bolts (13) 48 to 53 ft-lbs (65 to
72 Nm).
CAUTION
Rated capacity of lifting device must be at least 1000 lbs (454 kg).
b. Using overhead lifting device, carefully lift generator assembly and align with engine flywheel housing.
c.
Install bolts (12) and tighten alternately to draw generator assembly and engine assembly smoothly and evenly
together. Torque bolts (12) 19 to 21 ft-lbs (26 to 28 Nm).
The following step requires turning the generator by hand. Use engine fan to turn engine
and generator.
d. Align mounting holes and install bolts (6) and washers (7) securing fan (8) and drive plate (9) to flywheel (10).
Remove wires holding fan and drive plate together when installing bolts. Torque bolts (6) 29 to 31 ft-lbs (39
to 42 Nm).
e.
Install screen (4) on generator frame/stator assembly (5) with Iockwasher (3), washer (2), and bolt (1). Torque
bolt (1) 7 to 9 ft-lbs (9.5 to 12 Nm).
f.
Remove wooden wedges from between engine and skid base.
g.
Install generator mounting hardware, paragraph 3-6-2, step i.
h.
Install rear housing section, paragraph 2–20-4.
