More Comfort – More Performance – More Versatility


    A Cat® C3.6 engine, powerful hydraulics, and increased swing torque give you the power to move material with speed and precision.


    New, larger cab provides the space and visibility you need to keep you working comfortably and safely all day long.


    Offering the industry’s highest level of standard factory-equipped technology, including Cat Grade with 2D, Grade wth Assist and Payload.


    The 315 emits up to 8% less CO2 than the previous 315F.


Biodiesel Capability Up to B20¹
Bore 4 in
Displacement 220 in³
Emissions Meets U.S. EPA Tier 4 Final, EU Stage V, Japan 2014 emission standards.
Engine Model Cat C3.6
Engine Power - ISO 14396 110 HP
Engine Power - ISO 14396 (DIN) 111 hp (metric)
Net Power - ISO 9249 108 HP
Net Power - ISO 9249 (DIN) 110 hp (metric)
Note (1) Net power advertised is the power available at the flywheel when the engine is equipped with fan, air intake system, exhaust system and alternator with engine speed at 2,400 rpm. Advertised power is tested per the specified standard in effect at the time of manufacture.
Note (2) ¹Cat diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels** up to: 20% biodiesel FAME (fatty acid methyl ester)* or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels.Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations“ (SEBU6250) for details. * Engines with no aftertreatment devices can use higher blends, up to 100% biodiesel (for use of blends higher than 20% biodiesel, consult your Cat dealer).** Tailpipe greenhouse gas emissions from lower-carbon intensity fuels are essentially the same as traditional fuels.
