Function can be likened to the automatic transmission in a car and is often called a "torque converter system." The model 30 uses a 3/4 top width asymmetric belt. They have different angles. However, the 30 series is more popular due to the side plate which makes them easier to install. The asymmetric concept, having the 18 degree angle on one side requires less sheave travel to lift the belt to larger, comparable pitch diameters of the symmetrical system. Comet Terms Glossary Indicators of a torque converter system requiring cleaning and lubrication are erratic or jerky engagement upon acceleration and a tendency to apparently "lock" into a particular speed (a second cause of jerky engagement is an excessively loose drive chain).

It must be bolted tight against the crankshaft shoulder. Used on 20 and 30 series driver clutches . The 40-series torque converters have a 1:1 final drive ratio. 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. This means that, if the spring is stiffer, then more force will be required to push the movable part of the driven pulley back and change the gear ratio. 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.
