Why Choose Our Engine Rebuilding Service?

When it comes to remanufacturing your Cummins QSB4.5 engine, we utilize only ISO 9001:2015 approved parts that adhere to the strict tolerances set by OEM specifications. This meticulous attention to detail guarantees that your remanufactured engine will deliver the dependable power and performance you expect from your Komatsu D31P-20**. Our process is far superior to standard rebuilds typically performed in a garage environment, as we have invested in a specialized engine machine shop located in Concord, Ontario, equipped with state-of-the-art machinery.

Comprehensive Remanufacturing Process

Our engine rebuilding process is thorough and comprehensive, ensuring that every component is meticulously inspected and restored. We begin with the disassembly of the engine, followed by a series of cleaning processes, including manual scrubbing, degreasing, and ultrasonic cleaning. Each part is then measured against manufacturer specifications, and any necessary machining is performed to ensure a perfect fit for new components.

We take pride in our detailed 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 safe transport.

Brand New Surplus Engines Available

In addition to our exceptional rebuilding services, we also offer a selection of brand new surplus engines. If your Cummins QSB4.5 engine cannot be rebuilt, we can provide you with a new engine that fits seamlessly into your Komatsu D31P-20**. Our extensive knowledge allows us to transfer exterior components from your old engine to the new one, ensuring emissions compatibility and a hassle-free installation process.
