Features

Installation

Smaller in size than it's predecessor, the Cat C3.6 is a powerful engine in a compact and easily integrated size that saves OEMs valuable time and costs. With flexible aftertreatment mounting options and a simplfied engine installation process, the C3.6 can be placed into a wide variety of applications with agility and speed.

Advanced Features

What would you do with 5% more power density and 12% more torque? The C3.6 uses the latest in technology to bring OEMs the most efficient and powerful engine—even at peak performance—when compared to the previous engine model.

Ideal Applications

Industrial, agricultural and construction applications such as: Pumps • Compressors • Chippers • Grinders • Asphalt paving equipment • Hydraulic power units • Bore rigs • Drill rigs • Tractors • Telehandlers •

Total Cost of Ownership

Owning and operating equipment is a big investment, so it only makes sense to get the most you can from it. Thanks to the chosen technologies of the Cat C3.6, owners can experience an overall savings in fluid.

Cat Dealer Product Support
