Comprehensive Remanufacturing Process

Our engine remanufacturing process involves a series of detailed steps designed to restore your engine to peak performance. We begin with a thorough disassembly, followed by manual scrubbing and degreasing to remove heavy debris. Each component is meticulously cleaned using hot alkaline spray jet cleaning and ultrasonic cleaning methods. We then measure all components to manufacturer specifications, ensuring that every part fits perfectly.

We also perform critical machining processes, including cylinder bore machining, milling cylinder head surfaces, and cutting valve seats. Our technicians conduct rigorous testing, such as Magnaflux crack detection, to ensure the integrity of the cylinder heads. Once all components are prepared, we assemble the engine using new pistons, rings, bearings, and other essential parts, followed by a spin test to confirm functionality.

Brand New Surplus Engines Available

In addition to our comprehensive rebuilding services, we also offer a selection of brand new surplus engines for those situations where a rebuild may not be feasible. Our extensive inventory allows us to provide you with a new engine that fits seamlessly into your Komatsu D31P-20BE Crawler Tractor. We can assist in transferring exterior components from your old engine to ensure emissions compatibility and a perfect fit, minimizing any additional effort required on your part.
