Reliable, Quiet and Durable Power

Manufactured in some of the world's most modern and highly automated production facilities, the Cat® C1.7 is proven to deliver durable power and offers a wide range of customization options that refuse to compromise quality and durablity.

The stiff block and indirect injection system make this a quiet engine, minimizing operator fatigue and saving money forOEMs in sound attenuation measures.

High Performance

Substantial torque rise delivers impressive performance throughout a wide speed range while maintaining low operating costs.

Fuel Efficiency

Fuel consumption optimized to match operating cycles of a wide range of equipment and applications while maintaining low operating costs.

Broad Application Range

Wide range of factory configurable ratings and options for agricultural, material handling, construction, mining, aircraft ground support, and other industrial applications.

Compact Size

With a 18.9 kW (25.3 hp) power rating, the C1.7 allows OEMs to consider different installation, operating and commercialrequirements. This model is particularly adapted to machines which need high torque, low speed operation or good cold start capability.
