How to Find Your Model & Spec Numbers

To order the correct Cummins Onan generator parts and manuals, you'll need to know the model and spec of your generator set. If you don't already know this information, the steps below will help you identify it.

1. Can you read the information on the nameplate?

The model and spec of the set are indicated on the nameplate. The spec is the letter at the very end of the model information. Depending on the age of your set, the spec may or may not be clearly identified for you. Here is an example of a nameplate for a model KY spec K:

2. If you can't find or read the nameplate, can you find a serial number stamped on the generator set?

Call the Cummins Onan Customer Response Center with the serial number at 1-800-888-6626. Press 3 when prompted by the recording. They'll help you identify the model and spec letter you need to order parts and manuals. If you can't find the serial number on your set, they can help you determine where to look for it.

3. If none of the above helps you identify your Cummins Onan generator set, please contact your local Cummins Onan distributor or dealer.

Without nameplate information or a serial number, you may need to have a Cummins Onan dealer in your area look at the set to identify it. To find the nearest location, use the Cummins Onan Dealer Locator or call 1-800-888-6626 and press 1 when prompted by the recording.
