Aftermarket Parts for Caterpillar Engines

Caterpillar has a long and illustrious history. Starting in California (USA) with the manufacturing of steam tractor machines under the Holt Manufacturing Company. These tractors were used to build the Los Angeles Aqueduct which would bring water to the growing city. Holt also bought a patent from the company Richard Hornsby & Sons and trademarked it as “Caterpillar”, since it seemed to crawl like a caterpillar. Caterpillars were also the inspiration for the tanks of WWI. Since these times, Caterpillar has branched off into many lines of business including marine diesel engines. Of course, no matter how tough and durable the design of an engine is, regular use causes its parts to wear down, so they’ll eventually need replacing. And that’s where our team and online store at Diesel Pro Power comes into play.

With more than 30 years of dedicated service supplying aftermarket parts for individuals, private businesses, municipalities and others, we have all the parts for Caterpillar  you need to keep your equipment in top shape, whether that’s a part for one boat or multiple parts for a fleet of boats.
