Guaranteed like-new engine performance

Cat replacement engines cost 15-40% less than the cost of a major overhaul and substantially less than buying a whole new generator set.

Savings That Add Up

  • Reduced costs for repairing, testing, or sourcing individual components
  • Cat Reman options with core refunds can renew your engine's performance at a fraction of the cost of buying a whole new generator set.
  • Cat Reman engine components can support sustainability goals by reducing end-of-life waste through core returns

A Cat replacement engine can complement other upgrades you may be making to keep your generator set working at its full potential. When you replace your engine with Caterpillar, you’ll get a replacement engine from the original manufacturer, with like-new engine performance that will meet its original specifications.

Big Time Minimized Downtime

Big Time Minimized Downtime

Compared to a full engine overhaul, a Cat replacement engine will reduce repair time to get your generator set back to top-notch performance. 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 engine performance in the short time it takes to remove the old 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 18 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 will give you the best return on your investment. 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 drop-in solutions.
