EVERY 300 HOURS:  

 

Check  the  impeller  of  the  alternator  coolant 

pump.  

 

Replace the oil filter.  

 

Replace the fuel filter  

Replacement  depends  or  the  condition  of  the 

fuel.  We  recommend  replacement  every  300 

hours.  Isolate  the  fuel  supply  and  change  the 

element.  

 

EVERY 500 HOURS:  

 

Check the air strainer element 

 

Replace  the  impeller  of  the  alternator  coolant 

pump.  

 

When replacing the impeller the gasket between the pump 

case  and  the  cover  should  be  replaced  as  well.  So  when 

ordering a spare impeller order a gasket as well. Remove 

the  cover  to  get  access  to  the  impeller.  Remove  the  old 

impeller  with  the  help  of  two  screwdrivers.  Install the  new 

impeller  and  add  some  grease.  Turn  the  blades  in  the 

direction of rotation of the pump i.e. anti clockwise looking 

at the impeller.  

 

EVERY 1000 HOURS:  

 

Replace the V-belt.  

 

Retighten  the  cylinder  head  bolts  and  adjust  the 

valve clearance. (Refer to § 5.4.2).  

 

Check and clean the radiators 

 

EVERY 2000 HOURS:  

 

Replace or clean the air strainer element 

 

Check lubricating oil pressure  

 

Clean  and  check  or  replace  fuel  injector  nozzles 

and check injection pressure.  

 

Check the air filter element:  

The air is taken in via the cover on the alternator. 

Below this cover is a spongy material which filters 

the  air  and  holds  some  electrical  components 

which  are  cooled  by  the  inlet  air.  This  filter  does 

not  require  regular  maintenance.  Only  in  very 

dusty circumstances this filter should be cleaned. 

The spongy material can be washed in solvent or 

replaced.  

 

When  the  generator  set  runs  less  than  100 

hours a year the oil should be changed yearly

4.3.2 

Putting out of service  

When not using the generating set for a longer period it is 

recommended  to  execute  an  engine  preservation 

procedure.  

 

Clean the engine. 

Loosen  the  fuel  suction  pipe  and  fuel  return  and  put 

them  in  a  can  with  preservation  diesel  fuel.  Start  the 

engine and run the engine warm.  

Drain the hot engine oil and refill with preservation oil.  

Stop the engine.  

The coolant can stay in the engine 

Disconnect  the  battery  and  store  it  in  a  place  free  of 

frost and dry and charge it regularly.  

Close inlet- and outlet openings with tape.  

Protect  the  generating  set  against  the  influences  of 

bad weather conditions.  

 

This method of preservation will be sufficient for 6 months. 

Repeat  steps  2,  3,  and  4,  every  6  months.  Change  oil 

before using the engine again.
