Caterpillar Continually Strives to Improve Component Design and Manufacturing

 

We understand that normal engine operation subjects components to extreme stresses and temperatures. The use of Cat® and MaK parts greatly improves engine performance and reliability and reduces overall ownership and operating costs. 

Caterpillar has strategically located 70 parts distribution centers in 24 countries on six continents shipping to more than 200 countries worldwide to support your parts needs. Over 99 percent of the parts ordered by Cat dealers are shipped from Caterpillar distribution centers within 24 hours.

In addition, we offer engine repair options to help you minimize downtime.

Engine Upgrades Made Easy

Time to select the best upgrade for you

 

Thinking of repowering to improve performance or meet new emission standards? Before you do, consider giving your engine an upgrade. An upgrade can help you achieve the specifications you want, but with less investment than purchasing new. It’s a proven interim solution for customers navigating the energy transition, especially since upgrades can be implemented during a scheduled major overhaul so there’s no additional downtime.
