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.

Advanced Remanufacturing Process

Our remanufacturing process is far superior to the standard rebuilds typically performed in a garage environment. Located in Concord, Ontario, our specialized engine machine shop is equipped with state-of-the-art machinery that allows us to handle every aspect of the remanufacturing process in-house. This means we can maintain strict quality control and significantly reduce waiting times for our customers. From disassembly to final assembly, every step is executed with precision and care.

Comprehensive Engine Services

Our engine rebuilding service includes a detailed procedure that covers every component of your engine. We start with a thorough disassembly, followed by manual scrubbing and degreasing to remove heavy debris. Our advanced cleaning techniques, including hot alkaline spray jet cleaning and ultrasonic cleaning, ensure that every part is meticulously cleaned and inspected. We measure all components to manufacturer specifications, machining cylinder bores to accept new pistons and checking for warpage to guarantee a perfect fit.

We also perform critical tasks such as milling cylinder head surfaces, cutting valve seats, and testing valve spring resistance. Each engine is assembled with all new components, including pistons, piston rings, rod bearings, main bearings, and more. After assembly, we conduct a spin test to ensure everything is functioning correctly before packaging the engine in a corrosion-inhibiting bag for delivery.

Brand New Surplus Engines Available

In addition to our comprehensive rebuilding services, we also offer a selection of brand new surplus engines. If your engine is beyond repair, we can provide you with a new Cummins QSB4.5 engine that fits seamlessly into your Komatsu D31A-20E. Our team can assist in transferring exterior components from your old engine to ensure emissions compatibility and a perfect fit with minimal additional effort.
