How to maintain Cummins diesel generating set?

Do well follow three maintenance method, it is entirely possible to extend the mid-repair of your generator to 8,000 to 10,000 hours, and the overhaul to 15000 to 18000 hours.

A level maintenance

1.When use Cummins generator,check and record the operating state of the generator per hour.(check and record the power output,frequency, Oil pressure,water temperature, charging, smoke exhaust of the generator per hour)

2. Before open the generator,must check engine oil level and water level. (Before open the generator, let genset race 8mins, load on the genset when the sound of generator is normal.)

3. When the machine stop working,after genset cooled, need to clean face of genset. (Need to load on generator set firstly, let generator set race 10mins,then close down, so that let the pressurized gas and penalty kick be fully cooled. )

B level maintenance

Check battery water level（ half above zinc sheet 1cm ）
Check every machine belt tension ;
According diesel engine oil quality,change diesel oil grid every 200 hours to 300 hours;
Change generator oil grid every 250 hours to 300 hours;
Change wind grid every 500 hours(during working,can blow with wind gun 1time to 2 times)
Change water grid and add aqueous rust preventive every 500 hours.
Check control system every 500 hours or 3 months.
Clean water box heat sink network;

C level maintenance(every 3000 hours to 4000 hours maintenance by professional staff ）

Clean valve clearance of air door and adjust nozzle plunger stroke every 3000 hours to 4000 hours;
Clean ball bearing and inject lubricating oil every 4000 hours to 5000 hours;
Remove Holset turbocharger and remove carbon deposition, if necessary, change maintenance package of Holset turbocharger every 4000 hours to 5000 hours (This way can increase service life of Holset turbocharger)
Test the protection performance of the unit (such as: automatic shutdown of high water temperature, low voltage, overspeed, etc.);
Remove PT pump cleaning core every 3000 hours to 4000 hours;
Remove start motor and check carbon brush and contact copper sheet every 3000 hours to 4000 hours;
Remove battery charger and check carbon brush and bearing every 3000 hours to 4000 hours;
