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 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 access  doors. 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 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).
