3508C

Overview

Cat 3508C engines set the standard in the drilling industry. For many years the 3500 has been the preferred choice by drillers due to their high performance, durability, and reliability in the oilfield while maintaining low emissions.The ideal application for the 3508C engine is mechanical drive for land drilling rigs.Cat engines are backed by the worldwide network of Cat dealers ready to support your operation with technical support, service, parts, and warranty.3508C engines, with ratings: 671 bkW (900 bhp) @ 1200 rpm meet U.S. EPA Non-road Tier 2 equivalent and CARB Tier 2 equivalent emission standards. They are available using U.S. EPA and EU Flexibility, and for other regulated and non-regulated areas.
