Remanufactured Detroit Genuine Parts and Detroit Reman Engines

With beginnings in the early 1960s, the remanufacturing experience and expertise acquired through the years has made Detroit Reman an industry leader. Remanufactured Detroit Genuine Parts provide a cost-effective alternative to new parts with the same performance, durability and reliability.

Detroit Reman offers a continually expanding product portfolio, which includes engines, transmissions, turbochargers, axles and cylinder heads as well as electronics, aftertreatment systems and fuel systems products. For a complete list of Detroit Reman products, visit

Not simply rebuilt, the remanufacturing process begins by using only high quality cores and genuine Detroit replacement components, incorporates the latest design upgrades and restores products to OE specifications.

The Remanufacturing Process

Detroit Reman’s remanufacturing process includes disassembly, cleaning, inspection, recovery, reassembly and quality testing. The result is a part that meets or exceeds the same tough performance standards of a new part.

1. Disassembly

Cores are fully disassembled to their original parts. Some original parts will always be replaced with new. These parts, along with the unsalvageable parts, will be scrapped.

2. Cleaning

Various processes are used to fully clean each part to ready it for further inspection and possible re-use.

3. Inspection

Parts are inspected and those that meet Detroit Reman’s quality specifications are ready for re-use.

4. Parts Recovery

Salvageable parts that do not meet specifications may be improved using one of Detroit Reman’s recovery technologies.

5. Reassembly

Recovered parts along with required new parts are reassembled into finished components or engines.

6. Quality Checks and Testing

Once assembled, product testing ensures that remanufactured parts meet the same high quality standards as new parts.

Detroit Reman Recovery Technologies

Detroit Reman uses leading recovery technologies to restore worn surfaces. Additive technologies such as welding and spray processes allow restoration of components to dimensional specifications. Detroit Reman recovery technologies include:

Traditional Welding

Various welding processes are used to repair and recover damaged components.

Flame Spray Process

The flame spray process restores worn or damaged aluminum and cast iron surfaces and is used to recover a wide variety of components including some that are no longer available as new parts.

Twin Wire Arc Spray Process

Similar to the flame spray process, the twin wire arc spray process uses two wires as the feed material. The wires are melted with an electrical arc and are sprayed on the surface using a pressurized gas.

Cold Spray

The cold spray process allows small repairs to aluminum and cast iron. Cold spray applies powdered metal at a high velocity. Because the process does not melt the powder during application and introduces very little heat into the base component, it allows unique repairs that are not possible with other processes.

Plasma Transferred Wire Arc

his versatile surface coating process uses a single wire and a small rotating application head to coat hard-to-reach areas. Surfaces may be honed or cut back to original specificationss.
