GLOSSARYBogie WheelsThe wheels that form part of the suspensionsystem. They absorb shock, act asstabilizers, and exert downward pressureon the track so that it will have continuedcontact with the snow surface.BoreThe inside diameter of the cylinder.Brake DrumThe outer side wall of the fixed half ofthe driven pulley. The pressure of a brakeshoe, or disc puck, applied against thebrake drum, or brake drum disk, is theprinciple used to slow or stop the vehicle.Breaker PointsAn electric switch which controls thefiring time of the spark plug.Cam Slider ShoesNylon reinforcements that aid in the friction-freein and out movement of thesliding half of the driven pulley.Carburetor FlangeThat part of the carburetor body by whichthe carburetor is secured to the engine.Centrifugal GovernorThe cup portion of the drive pulley containingfour flyweights.30Chain TensionerSelf-adjusting, friction-free block, usedto maintain correct drive chain tension.Ski RunnersReplaceable steel rods located under theskis, that aid steering control and alsoprevent ski wear on hard surfaces.SprocketsPolyurethane or rubber toothed wheels,located on drive and rear axles.
