State-of-the-Art Facility

Located in Concord, Ontario, our specialized engine machine shop is fully equipped with all the necessary machinery to restore your Cummins QSB4.5 engine to its original specifications. By keeping all machining work in-house, we minimize waiting times and ensure that your engine is rebuilt efficiently and effectively. Our team of experienced professionals is dedicated to providing you with a reliable engine that you can trust for your heavy-duty applications.

Comprehensive Remanufacturing Process

Our engine rebuilding process involves a series of detailed steps to ensure that every component is thoroughly inspected and restored. We begin with the disassembly of the engine, followed by a meticulous cleaning process that includes manual scrubbing, degreasing, and ultrasonic cleaning. Each part is measured against manufacturer specifications, and any necessary machining is performed to ensure a perfect fit for new components.

We take pride in our comprehensive approach, which includes checking for warpage, milling cylinder head surfaces, and testing valve spring resistance. Our skilled technicians assemble the engine using all new parts, including pistons, piston rings, bearings, and gaskets, ensuring that your engine is as good as new. Once assembled, we conduct a spin test to verify performance before packaging the engine in a corrosion-inhibiting bag for delivery.

Brand New Surplus Engines Available

In addition to our engine rebuilding services, we also offer a selection of brand new surplus engines. If your engine cannot be rebuilt, we can provide you with a new Cummins QSB4.5 engine that is ready to be installed in your Komatsu D31E-20. Our extensive knowledge of your old engine allows us to transfer exterior components to the new engine, ensuring emissions compatibility and a seamless fit into your machinery with minimal additional effort.
