Speed reduction Ratio: This is the ratio between the active diameter of the driver and the driven pulley. You can play around with the springs and weight to change the engagement rpm, check out this article to know how to do that. Comet Industries USA. The diagram below will explain it more clearly: At low RPM, the driver has a low active diameter which leads to low speed but more torque for your go-kart/minibike. All the black plastic insert buttons must be in place at all times. Buy the Spring and the weight and swap out the old ones. 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. They have different angles. Home Page Used on 20 and 30 series driver clutches.Comes with 2 springs. Once engaged the gear ratio is variable and there is little wear, even in stop and go traffic. How To Identify Comet Torque Converters, Service Tips Page Continue through the site to learn more about Comet Torque Converters.

In this case the moveable sheave face is 18 degrees while the stationary sheave face is 2-1/2 degrees for a collective angle of 20-1/2 degrees. As torque converters handle low torque ranges more easily, theyre most commonly used on off-road go-karts. Thank you sir. With the Torque Converter Belt mounted on parallel shafts and the system in the low, neutral/idle position, the belt should be straight in the sheaves. Proper installation is necessary to prevent any damage to the engine. Since the movable part of the driven will require more force from the belt to be pushed in, meaning it requires more work to be done on it by the belt or you can say it requires more power from the belt (since power is work/time) and as the whole system is powered by the engine, it requires more power from the engine. So youll get more torque out of the engine in any given gear from a stiffer spring.

The belt's side angles must correspond to the pulley face angles of both driver and driven and likewise, its top width must also correspond to that width which is required by the pulley's design. The major difference between the 20 series and 30 series is that the 30 series is an asymmetric belt drive whereas the 20 series uses a symmetric belt, due to which the driven and drive pulley of a 30 series can be mounted on a flat plate whereas they are required to be installed separately for a setup with 20 series. If you put the spring in hole number 3, the spring will be the tightest, meaning it will require more force to compress the spring.
