Our Remanufacturing Process

Komatsu, CAT, Cummins Rebuilding Specialists

At Diesel Sales, we specialize in the remanufacturing of most models of Komatsu, Cummins, and CAT diesel engines for off-road applications. We completely transform an engine and make it new again in our 40,000 square foot remanufacturing facility. We also carry a complete line of on-highway truck engines. A remanufactured engine built to your exact specifications reduces your installation cost and out-of-pocket expenses. We operate six days a week to reduce lead-times on our reman engines and to provide a better purchasing experience for our customers.

We dyno-test every Diesel Sales reman engine before it goes out the door. Each engine is load-tested to measure the engines force, torque, horsepower and overall fitness. Dyno testing ensures field-readiness upon arrival for our customers.

Why Remanufacture?

Remanufacturing an engine is a great alternative to buying a brand-new engine. (If the core is in good enough condition, of course). Remanufacturing an engine with new parts ensures the same compatibility of the engine and the application the engine is being used for (forklift, crane, etc.). This also assures better operation of an engine, as all new parts installed meet or exceed OEM specifications. Remanufacturing an old engine is more cost-effective for the customer as well as beneficial to the environment. Give us a call today to receive a quote!
