Cut downtime in half

Quick turnarounds are our specialty, giving you the flexibility to choose what’s best for your operation’s schedule.

Good-as-new engine performance

Each Cat replacement engine is designed by the original manufacturer (us) for like-new performance. We ensure your replacement engine will meet or exceed original machinery specifications, so you can get back to work with confidence – in record time.

of

Cost-efficient

Cat replacement engines give you like-new engine performance at a fraction of the cost of new. Our high-powered, cutting-edge engine solutions also maximise the performance potential of other machine refurbishments to boost your all-around productivity and bottom line.

Simpler than overhauling

Got extra time for disassembly, inspection, cleaning, ordering, reconditioning and reassembly? Didn’t think so. Cat replacement engines get you back to tip-top shape and top-notch performance in no time, especially when compared to the slog of machine overhauls. With Cat replacement engines, you get like-new performance in the short time it takes to remove the old and assemble and install the new.

Boost small engines.

While Cat replacement engines are always a sound option for your fleet, they work particularly well with small engines from 0.5 to 7.1 litres. Treat the little guys right (and skip the overhaul) with the boost from a Cat replacement engine.
