CCW Snowmobile Engine Specifications

Curtiss-Wright, a company with roots back to the Wright brothers as evidenced in its name, sold engines for snowmobiles through its Canadian Curtiss-Wright presence. Those engines powered snowmobiles like the ones made by John Deere during the 1970s. In 1971, CCW promoted two engines with an advertisement featuring an appearance at the Minneapolis International Snowmobile Trade Show in June of that year.

  1. Capacity

    • The two 65-pound engines promoted by CCW in 1971 were the 340 and 400. Those numbers represent the engine's capacity, or volume of a cylinder when the piston remains pushed out, which is also known as engine displacement. The actual capacity of the 340 measures 339.1 cubic centimeters, while the 400 lists at 398.2cc.

    Ignition

    • Both of the CCW snowmobile engines come equipped with an auto advance flywheel ignition with lighting coil requiring 12 volts of energy for starting power while consuming 75 watts of energy. The starter is a rewind with emergency starting pulley in the event of the electric starter failure. The electric starter for both engines has an output of 0.5 kilowatts.

    Power

    • The 340 engine generates 25 brake horsepower, while the 400 rates at 30 bhp. Both are two-cylinder, two-stroke engines with the stroke, the length of the piston going up and down, the same in each engine at 60 millimeters. The bore, or diameter of the cylinder, lists at 60mm for the 340 and 65mm for the 400. Both engines come equip with an axial blower for more effective cooling during operation. Two-stroke engines require a lubrication mixture of gasoline and two-stroke motor oil with the ratio in each engine of 20:1.
