4-41. AIR CLEANER ASSEMBLY.
a. Inspect (see figure 4-37). On ASK equipped generators,
open air intake door and air cleaner door.
(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 con-
nections, 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
access doors.
(1) Air Cleaner Assembly. Check air cleaner
assembly for corrosion, broken or dented components
or split hoses.
b. Remove.
(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
turning counterclockwise.
(2) Remove nut (17), lockwashers (18), screw
(19) and separate air cleaner (20) and bracket (21).
c. Repair.
(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.
d. Install.
(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 air flow indicator (16) on air cleaner.
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 (MEP-003A) or 400 HZ ( M E P -
112A). Apply full rated load to engine. Check that
governor adjusts engine quickly, smoothly, and with-
out 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
and Services.
d. Adjust. The only engine adjustments applicable
to this level of maintenance are to the valve rocker
arms stop solenoid. and starter lockout switch.
NOTE
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).
