The Cummins R2.8 Turbo Diesel (PN 5467046) has demonstrated through the testing procedures prescribed in 40 CFR Part 86 to meet EPA’s Tier 0 (LDT 1 and 2) and Tier 1 emissions standards (LDT 2 weighing less than 4000 lb. complete weight). This means that the R2.8 generally is suitable for Model Year 1999 or earlier light duty trucks. However, the suitability of the R2.8 engine to any vehicle is the responsibility of the installer and may depend on state or area laws. Installation of this part in a vehicle for which it is not intended may violate U.S. and Canadian laws and regulations related to motor vehicle emissions. Check your state and local emissions requirements before purchasing.

Due to state / provincial law restrictions, these engines are not currently available for purchase in the state of Texas or the province of Quebec.

Even for non-CARB states, the general rule of the Federal Clean Air Act says that a modification to any emissions control device needs to be as clean or cleaner than the part which is being replaced. It is the consumer’s responsibility to follow the letter of the law, despite the presence of vehicle emissions testing in your region. Cummins will dissuade such behavior by refusing to service illegal installations and the vehicle owner or builder is liable for any potential legal/compliance fallout associated with improper use of the certified products.

The first thing to do as soon as you have any issue is to call 1-800-CUMMINS and tell them that you have an R2.8 Turbo Diesel Crate engine, give them your ESN, and they will give you instructions on next steps.

If you are near a Cummins location, you can also take the failed component, ESN, owner information, date of purchase and receipt to your local distributor parts counter and request 'parts warranty.'

If you have a component fail outside of warranty, please contact 1-800-CUMMINS to report the issue and to ensure there is no recall on the part.

The Cummins distributor network offers genuine parts to support each engine in the Repower family. You can find the nearest parts dealer by using parts.cummins.com and create a picklist using your engine serial number.

This sets Cummins Repower engines apart from the illegally imported junkyard engines where the service parts also need to be imported as well.

Any authorized Cummins distributor has the capability to service Cummins Repower engines using the same tools and resources that are used to service all other commercial Cummins products.

This sets Cummins Repower engines apart from the illegal junkyard engines conversions where there is no OEM support model in place.

Cummins utilizes the vast Specialty Equipment Market Association (SEMA) network in order to provide relevant information to third parties who plan to bring ancillary product to market. Tools such as the SEMA Garage and Tech Transfer program are being used be the prime path to sharing approved information to qualified suppliers.

Look for a quality SEMA member in the aftermarket who have experience with the R2.8 Turbo Diesel or search social media for “#cumminsrepower” to see what customers are using.

The current R2.8 PN 5467046 is designed to use a manual transmission. The J1979/1939 CAN data link is broadcasting engine speed and throttle position messages that allow aftermarket automatic transmission controls to be integrated.

The aftermarket currently offers the following adapters: GM manual GM automatic Jeep AX15/NV3500 Jeep NAG1 FCA/ZF 8HP70 8-speed Land Rover (various) Toyota (various)

The R2.8 is based on a proven global platform that has powered many applications around the world for nearly a decade. Like any other engine manufactured by Cummins, it has gone through stringent real-world and test cell testing and is continually being improved if we identify a quality issue to ensure that the engine lives up to the Cummins brand promise of dependability. Test vehicles equipped with R2.8 have racked up thousands of trouble free miles in the most extreme duty cycles in vehicles ranging from otherwise stock to 38” tires at all altitudes and in all temperatures.

Some websites online who make a business of pedaling used and illegal junkyard imported engines for swaps have made false claims against our products in order to protect their business model but our product and customer support speak for itself.

The facts are that when you buy an illegally imported junkyard engine, you know nothing about the engine’s actual history, the real mileage, how long it has set in the elements or in a shipping container on the water. The engine never had an EPA rating to begin with and if the seller is offering any warranty at all, it’s likely just to get more junkyard parts that need to be imported as well since the product was never for sale in the US.

In addition to the clear benefit of the product being new and factory built versus something that has sat in a wrecked vehicle in a junkyard out in the elements, buying a Cummins Repower crate engine gives you the peace of mind that a company like Cummins is actively standing behind your product. Cummins tests, tunes, validates every offering and even after the purchase offers updates and improvements to calibrations as they become available. We have an active customer service and support model as well as genuine parts availability which is unmatched by any junkyard.
