Getting the Right Part the First Time

Automotive Light Duty Diesel Applications

To supply you with the right part the first time we use many tools. For automotive, light duty diesel we use application guides for selecting the correct part based on model year. There could be mid-year engine build breaks that we must know to determine the correct part. Vehicle manufactures usually release new models in September of the year before.

A mid-year build may be due to an emissions change, where the build is based on the engine build date, not the pick-up truck build date. Other engine build differences can change at anytime. For example Ford has changed builds in February, April, June, mid September and early December. These build date breaks are often engine serial number based. If there is a build date change, we will ask “early or late?” or for numbers off the product to get you the correct parts.

A lot of people call and say “I have a Cummins” when in reality you have a Dodge / Ram with a Cummins engine. Many people do not realize that Cummins has over 300 different builds for the 5.9 L engine from on-highway, off-highway and marine. Since we work on fuel systems for all the different builds, we need more information.

Heavy Duty or Off Highway Applications

Name plate information such as part number, model number, and set code are important for many applications, below are just a couple of samples. More can be found here Nameplate and model number, where to find them

For heavy duty and off highway applications we need the part numbers off the injection pump or injectors. The application guides for heavy duty and off highway are incomplete. They rely on engine manufactures to inform the Fuel Injection Equipment (FIE) Manufactures of the exact application. This is rarely complete for one reason or another.

Trying to order by engine model doesn’t work well either. The Perkins 4.108, for example, used 5 different injector part numbers. Cummins, as noted above, has hundreds of engine builds for the 3.9, 4.5, 5.9, 6.7 etc. Case D188 and D207 have two dozen different builds.

Some engine manufactures have accurate parts lists based on engine serial number. Cummins and Caterpillar have good parts lists that are accurate, by s/n.

John Deere has a lot of inaccuracies in their parts look ups. We have even had John Deere dealers order the wrong injection pump based on their parts catalogs.

When a vehicle or equipment manufacture buys an engine from a different manufacture, they usually make up their own part numbers. Caterpillar for example uses Perkins, Mitsubishi, Iseki and Ishikawajima engines. Cat makes up their own part numbers for the engine components. The FIE manufactures cross-reference only works on the OE engine manufactures number.

Caterpillar, John Deere (Yanmar), Cummins (Komatsu), Bobcat (Perkins, Kubota, Doosan, Mitsubishi, Deutz, Cummins), Universal, Case (Iveco, Fiat), JCB, AGCO, Massey Ferguson (Perkins, SISU, Mitsubishi) and others make up part numbers that do not cross-reference to the FIE OE number. This is why we need the numbers off the injection pump, injectors or turbo to supply the correct part.

Providing the numbers off the pump, injectors or turbo will help you get the right part the first time.
