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 ensures no part is overlooked. We begin with the disassembly of the engine, followed by thorough cleaning processes such as hot alkaline spray jet cleaning and ultrasonic cleaning. Each component is meticulously measured and machined to meet manufacturer specifications. We also conduct rigorous testing, including magnafluxing cylinder heads for crack detection and testing valve spring resistance, to ensure every part is in optimal condition before reassembly.

Brand New Surplus Engines Available

In addition to our rebuilding services, we also offer a selection of brand new surplus engines. If your Cummins QSB4.5 engine cannot be rebuilt, we can provide a new engine that fits seamlessly into your Komatsu D31PG-20E. Our team can assist in transferring exterior components from your old engine to the new one, ensuring emissions compatibility and a hassle-free installation process.
