Remanufacturing diesel engines

How Our Technicians Reman Your Old Core

Upon receiving a core or a customer’s old, used engine 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 for cracks and other damage. Once the cleaning of these parts is complete, they are carefully inspected for cracks and other damage. If these parts pass inspection, they are machined to return to manufacturer specification. As a result, this ensures all parts are working as new.

After Remanufacturing

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 for up to four hours, assuring the engine is running like new for our customers. During Dyno testing, the engine is inspected for leaks.

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

Once our engine technicians are certain the engine is ready and fit enough to be installed in a piece of equipment, the engine is shut down and drained of fluids. After a thorough cleaning, the engine is painted with OEM paint. Finally, once the engine is dry, it is shrink wrapped, crated, and shipped to the customer.
