Become a DIY expert with our Cummins Service Repair Manuals

The Cummins Service Repair Manuals that we offer are all authentic and produced by Cummins. Often, you will encounter information in manuals that were compiled by third parties — this information is not as complete and concise (or even accurate) as the materials produced by Cummins.

Cummins-Manuals.com is a trusted resource for both owner DIYers and corporate clients that want the necessary reference material on hand to service their own fleet of equipment.

Our inventory features:

  • Both new and gently used Cummins service manuals. We promise that, whichever manual you purchase, it will arrive in great condition and completely legible.
  • Manuals that contain step-by-step instructions on diagnosis, repair and maintenance for your Cummins engine or generator. This includes detailed diagrams that will make it easy to visualize each step of the process.
  • One of the largest selections of Cummins manuals in the country — and even the world. Not only do we have access to over 200,000 service manuals at any given time, but we also have a large network of professionals that we lean on to acquire those hard-to-find manuals. We offer manuals that date back as far as 1912.

“Great Service, knowledgeable staff, on time like promised!!! Thanks for your service!”

All of our manuals come with a 14-day, money-back guarantee (you are responsible for a re-stocking fee). These manuals are affordably priced, ship quickly and for the lowest shipping rates possible. We service Cummins Customers across the world — there is no limit on where we can ship.
