Cat 3508B 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.The ideal application for the 3508B engine is mechanical drive for land drilling rigs.3508B engines, with ratings: 671 bkW (900 bhp) @ 1200 rpm meet U.S. EPA Non-road Tier 1 equivalent and CARB Tier 1 equivalent emission standards. They are available using U.S. EPA and EU Flexibility, and for other regulated and non-regulated areas.
