Caterpillar Diesel and Natural Gas Engine Overhaul Shop

When your engine needs more than just a tune-up to get it in the best possible shape, an overhaul or rebuild is the solution. 

At Worldwide Power Products’ new location in Northwest Houston, we offer rebuilds and overhauls for generators, gas compression engines, diesel engines, and pump engines for mining, dredging, or machinery.

Our technicians’ extensive Caterpillar overhaul experience allows you to enjoy the benefits of this process, from better fuel efficiency and improved emissions to longer lifespan and opportunities for customization.
