Service & Maintenance Plan for Cummins Genenerator Sets

  1. Genpart Services Ltd works with definite service schedules for all maintenance and service contracts for Cummins engines. We do this by:-
    Direct contact with the Client’s technician assigned to oversee power backup functions for Help Desk support. They are responsible for daily, weekly and monthly checks and should fill a Generator Maintenance Template and email it on schedule for our assessment.
  2. Major servicing is a prerogative of the Genpart Services Ltd technical team every 400-500 hrs depending on engine type.
    We provide them with the Generator’s Operation & Maintenance Manual (OMM) although these available for free download from manufacturers or authorized distributor web spheres. We have included a sample copy for download on this page.
  3. The manuals provide detailed information on regular maintenance which ensures engine runs optimally and economically.
  4. Cummins have the "Cummins QuickServe Online (QSOL)" which can be the best source for Cummins parts, service and maintenance help – and this great app puts it in the palm of your hand. The QSOL app provides easy, on-to-go access to part options, parts catalogs, a fault code analyzer and engine dataplate information for more than 15 million Cummins serial numbers. Many other apps by third-party service support are easily downloaded for free from Google Play Stores eg The Cummins Power App, Cummins Engine Parts & Support by Torquepower Diesel (Australia) Pty Ltd, among others
  5. Our Service Contracts, however do NOT require the technicians to get troubled with any technical issues except for daily/weekly/monthly checks, because we schedule maintenance as per the manufacturer’s recommendations (see Major Service below).


Daily checks:


  • Cooling system coolant level
  • Driven equipment
  • The engine air cleaner service
  • Engine air pre-cleaner, cleaning it if necessary
  • Engine oil level
  • Fuel system primary filter/water separator
  • V-belts
  • Walk-around inspection

Weekly checks include:

Fuel tank, water and sediment, draining if necessary

Major Service (Genpart Services Ltd Team)

  1. Major service intervals are typically every 400-500 hours for minor services and in multiples of 400-500 hours for major services e.g. 800 -1,000, 1,600-2,000, up to 4,000 hours
  2. Each engine we supply comes with a detailed list of checks for you to carry out at set intervals
  3. We use shared Google Calendar to enter details of scheduled maintenance and in cases of Mobile App use, reminders when engine service is due.
