R2.8 Turbo Diesel
Not all engines are crated equally. When critical components such as fuel pumps, filters, accessories, starters, and flywheels aren’t included in an engine package, you have to piece together these components from various manufacturers, hoping for the best. For the vehicle specific components not included with our R2.8 Turbo Diesel, such as motor mounts and cooling packages, we help you by including the most thorough installation guide and owner’s toolkit available in the crate market, as well as on-call support from 1-800-CUMMINS. A team of dedicated enthusiasts is standing by to help.

The Cummins R2.8 Turbo Diesel (PN 5467036) 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 installation guide discusses general aspects of the installation into a suitable vehicle, ancillary system considerations, and also specifications and dimensions for the majority of components.
