Remanufacturing diesel engines

Remanufacturing Diesel Engines

We specialize in remanufacturing off-road diesel engines. We also supply most remanufactured on-highway diesel engines for trucks. After being machined, our professionally trained engine technicians take an engine core and rebuild it from the ground up.

See our remanufacturing process here.

Remanufacturing a diesel engine is often a great alternative to purchasing a new engine. Remanufacturing your engine allows us to build a complete drop-in for you. This reduces your labor costs to install and ensures a perfect fit. Remanufacturing is more cost-effective. Dyno testing our remanufactured engines begins the break-in process. Once installed, it is ready to go to work.

How Our Technicians Reman Your Old Core

Upon receiving a core, the engine is thoroughly cleaned. After that, it is then disassembled into component parts and inspected for damage. The block, head, crankshaft, and rods are sent to the machine shop, where these parts are put into a vat of degreasing solution. This step removes dirt and grease so that the parts can be inspected. Once cleaning is complete, they are carefully inspected for cracks and other damage. If these parts pass inspection, they are machined to return to manufacturer specification. This ensures all parts are working as new.

The Machined Engine Core is Rebuilt with the Following New Parts:

  • Pistons
  • Piston Rings
  • Wrist Pins
  • Snap-Rings
  • Rod Bushings
  • Cam Bushings
  • Liners
  • Sleeves
  • Rod, Main, and Thrust Bearings
  • Water and Oil Pump

After Remanufacturing: Dyno Testing!

Once the engine rebuild is complete, all Diesel Sales remanufactured engines are Dyno tested. Dyno testing ensures the engine is ready to go to work, and all remanufacturing steps have been completed properly. Our remanufactured engines are Dyno tested under load for up to four hours. Dyno testing ensures the engine is operating at the right speed and temperature. It also makes sure the engine is running at optimal horsepower and tests for torque.

The break-in process begins while the engine runs on the Dyno. As the engine continues to run, it is warmed to operating temperature. This tests the engine in stages while checking the oil pressure, water temperature, and exhaust temperature.

Once our Dyno technician is certain the engine is ready to be reinstalled, the engine is shut down and drained of fluids. After a thorough cleaning, the engine is painted with OEM paint. Once the engine is dry, it is shrink wrapped and shipped to the customer.
