Reliability - Toromont Remanufacturing completely disassembles engines and long blocks in accordance with strict Cat standards. We use Cat parts, updated for all engineering improvements. Cat is the leader in establishing reusability guidelines that go above and beyond industry standards which will ensure a full service life. All components are measured against these strict guidelines and are backed by our industry leading warranty.

Extensive Testing & Cleaning - Prior to assembly, all engine components are rigorously tested. The complete engine is fully tested and adjusted using an 1800hp or 1000hp dynamometer to meet and exceed all Cat specifications. Each unit is cleaned in our state-of-the-art Kolene molten salt bath, removing all paint, carbon, oil and soil permitting a thorough inspection of bare castings. High pressure - high volume cabinet washers, ultrasonic cleaners, shot blast units and glass bead machines ensure all parts are thoroughly cleaned.



Rigorously tested for optimum performance.

 - Each cylinder head is fully disassembled, magnafluxed and pressure tested for cracks, erosion and other damage. We thoroughly inspect and test each part according to rigid manufacturing specifications. This ensures tight sealing, prevents stress warping, cracking and premature wear.

Toromont Remanufacturing's skilled specialists service each block, inspect and magnaflux for cracks, main bore diameter, deck height, upper and lower bores, lifter bores and other critical dimensions that affect performance. We also ensure that each block is aligned bored using OEM specifications and resurfaced to ensure proper finish.

Counter bores are machined and steel inserts are installed when necessary to ensure sizing specifications are met. Lower bore sleeve inserts are installed and machined to OEM specifications when necessary to ensure proper liner seating.

The crankshaft goes through a process of grinding and polishing ensuring the proper size and surface finish is achieved. Size, run-out, taper and radii are all 100% inspected and controlled.

Each camshaft is inspected for straightness, polished and ground to obtain the proper size, taper and surface finish.
