This makes it possible to force the belt to a diameter within the drive clutch (at high RPM) that exceeds the usual 1:1 ratio of standard systems. 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. This offers some very significant advantages to mounting requirements in many cases. This is the only system designed to operate this way, thus providing the proper alignment for the final drive chain to be on the same side of the vehicle as the P.T.O. Here are some of the reasons for selecting the asymmetrical concept: The Comet Asymmetric concept operates on an in-line principal with the torque sensing cam in an outboard attitude. 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. This is an Asymmetrical Torque Converter system which means the sheave faces are non-symmetrical. Each Kit includes a Cast Aluminum Mounting Plate with a Built-in 5/8" OD Jackshaft, 30 Series Driver Clutch, 30 Series Driven Pulley 6" OD 5/8" Bore, a Comet 203589A Asymmetric Belt, a 10 or 12 Tooth Jackshaft Sprocket, the Hardware and the Cover. These Kits bolt to the side of the engine. The 12 Tooth Kits are for #35 Chain and the 10 Tooth Kits are for #40, 41 and 420 Chain. Choice of 2 different Jackshaft Sprockets.
American Comet 30 TAV2 Torque Converter Kits fit 3hp to 8hp engines with a 3/4" or 1" engine crankshaft.
