Upper and lower nut must be tightened evenly
in small increments so that muffler will lay
flat against adapters.
Bend lock tabs (2) up to secure nuts (1).
4-41. AIR CLEANER ASSEMBLY.
a. Inspect (see figure 4-37). On ASK equipped generators, open
air intake door and air cleaner door.
(1) Air Cleaner Assembly. Check air cleaner assembly for
corrosion, broken or dented components or split hoses.
(1) Air Cleaner Assembly. Loosen hose clamps
(9 and 11) attaching two air intake hoses (10 and 12)
to housing and detach hoses. Remove screws (13),
lockwashers (14) and remove air cleaner and bracket
and spacers (15). Remove air flow indicator (16) by
(2) Remove nut (17), lockwashers (18), screw
(19) and separate air cleaner (20) and bracket (21).
(1) Air Cleaner Assembly. Weld and straighten
air cleaner housing as necessary.
(2) Mounting Bracket (see figure 4-37). If bracket
(21) is split or bent, weld and straighten bracket as
necessary. After completing repairs, check that
bracket securely attaches air cleaner to set.
(1) Air Cleaner Assembly (see figure 4-37).
Install air cleaner (20) on bracket (21) and secure
with screws (19), lockwashers (18) and nuts (17).
Install airflow indicator (16) on air cleaner.
(2) Install air cleaner, bracket and spacers (15)
on generator housing and secure with lockwashers (14)
and screws (13). Install hoses (10 and 12) and secure
with clamps (9) and (11).
4-42. ENGINE ASSEMBLY.
a. Inspect (see figure 1-1). Inspect engine for loose
connections, leaks in oil and fuel systems, and free action of all
moving parts. Check that engine is securely mounted to skid-
base. On ASK equipped generators, inspections of the engine
assembly are limited to components accessible through the
b. Test. Operate engine with no load on Generator
Set, until it warms up to normal operating tem-
perature indicated by shutters being in an inter-
mediate position between open and closed. Check oil
pressure. Oil pressure should be 20-45 psi. Check
frequency on frequency meter. Frequency should be
approximately 60 Hz indicating that engine speed is
about 1800 RPM. Apply full rated load to engine.
Check that governor adjusts engine quickly, smoothly,
and without excessive hunting. Check that exhaust is
normal under load. Check that engine runs without
excessive fuel or oil consumption. Check that no
unusual noise is heard. Inability of engine to meet
these tests may indicate engine malfunctioning. See
Troubleshooting, Section VI.
c. Service. Service engine according to the schedule
given in table 4-1, Preventive Maintenance Checks
d. Adjust. The only engine adjustments applicable
to this level of maintenance are to the valve rocker
arms, stop solenoid, and starter lockout switch.
Engine lifting attachment is for lifting engine
alone. Do not use this attachment for lifting
engine if generator is still attached. Use the
set lifting eye for this purpose (see figure 1-1).
