Vital factors in this proper alignment are (1) that the engine crankshaft and drive shaft (jackshaft) be aligned perfectly parallel: (2) that the drive clutch be aligned to have the belt run at its highest speed (3) that the driven unit sheaves open to the proper dimension for the highest speed range, which is assured by using a belt of the proper width and with the proper collective angles (4) that the center distance between engine crankshaft and driven shaft be correct for the drive belt as specified and (5) that the drive belt have the correct outside circumference and proper top width. Keys to proper operation of the drive system are that the entire system be aligned and adjusted properly.

Even engine and drive train component life (sprocket, chain, bearings, etc) is extended since shifting is smooth and not subject to the hazards of manual control. Since ratio selection and "down-shifting" is automatic, braking and vehicle control are enhanced. The unique design of the "movable face" in each "driver" and "driven' member cause automatic, infinite variation and thus smooth shifting action between the system's low and high range in immediate response to chainging load and/or travel conditions, with constant optimum ratio between engine and drive wheel thus assured, you get the use of all the power your engine develops. Utter simplicity makes both cost of this equipment and its installation modest and also reduces future maintenance to a negligible minimum without compromise of performance of versatility.

There are no gears, no complicated controls or levers and neither manual shifting nor clutching is involved in these systems.

Each Comet system is fully automatic and can be used anywhere that control by engine throttle alone is desireable.

The variable speed drive system normally consists of an engine clutch (1), and a driven unit (3), connected into a system by a "V" type belt (2).
