With Cat replacement engines, you can bring your genset back to like-new engine performance at a fraction of the cost of buying a whole new genset. 

A replacement engine can complement other upgrades you may be making to keep your equipment working at its full potential. Improve uptime and maximize productivity to get the most out of your investment.

Big Time Minimized Downtime

Big Time Minimized Downtime

Compared to a full engine overhaul, a Cat replacement engine will get you back to tip-top shape and top-notch performance in no time. Overhauls can be a lengthy process involving disassembly, cleaning, inspection, parts ordering, reconditioning, reassembly, testing, and more.

When you choose to replace your engine, you get like-new performance in the short time it takes to remove the old and assemble and install the new.

Biases aside, while Cat replacement engines are always a sound, cost-effective solution, it’s even more true for small engines, especially 0.5 to 7.1 liters.

The intensive labor and repair time that comes with any engine overhaul may not be the best investment for a smaller genset. Work smarter, not harder for your smaller Cat engines.

Cat Engine Repower – Long and Short Blocks

An economical approach to repowering your electric power generator set, Cat Long and Short Blocks deliver a whole lot of bang for your bucks. Much of this value lies in the reuse of workable components in a failed engine. 

So, if you’re looking for a faster turnaround genset engine repair, superior quality, reliability, and lower costs, we have your solution right now with immediate off-the-shelf availability.
