How much horsepower does a Caterpillar D342 engine have?

The Caterpillar D342 engine's horsepower varies depending on its configuration and application. There isn't one single horsepower rating. You'll need to specify the exact model and application (e.g., D342-XXXX where XXXX denotes a specific model variation) to get a precise horsepower figure. Caterpillar's official documentation or a dealer would be the best resource for this information.
