Manco go kart torque converter6/20/2023 Center distance is used as a reference to assure correct set-up, when considering a specific belt O.C. 90:1 or 10% over-drive.ĬENTER DISTANCE (C.D.): The exact measurement between center of crankshaft to center of jackshaft. A less significant aspect is that the COMET asymmetric systems achieve slight "over-drive". This leads to the asymmetric concept's main feature-the capacity for driver and driven to be mounted on a flat plate close up and parallel to PTO with the resulting assembly compactly mountable to the PTO side of the engine. Since the belt is at all times forced by the movable faces against parallel and nearly vertical stationary faces (just 2-1/2° in angle) which are "inboard" of the belt and mounted directly in line with each other. Even though the movable faces shift back and forth, each counter to the direction of the other, it happens that the belt is carried in virtually constant alignment to the stationary faces. In this special system concept, both the driven's and the driver's movable faces and the driven's torque sensing cam/spring mechanism all are on the same side."outboard" of the belt. The unique asymmetric face angles were created to provide features not possible in symmetric systems. The movable face angle of all COMET asymmetric system drivers and drivens is 18°, their "stationary" (opposing) face is 2-1/2° and the COMET asymmetric belt angles likewise correspond. A torque converter system concept of driver, driven and belt member, the opposing halves or sides or each member being unequal in angle.
