Comet TAV 30 Torque Converter

This is the Torque Converter is for use on larger engines with a 1" Crankshaft. This unit has a mounting plate that simply bolts onto the engine.

This Torque-A-Verter has a cast aluminum mounting plate that bolts right onto the engine. Mounting hardware and installation instructions included.

This is an asymmetrical type torque converter system which means the sheave faces are non-symmetrical. They have different angles. 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. 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. 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. This offers some very significant advantages to mounting requirements in many cases. 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 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 TAV 30 can actually attain an .90:1 or 10% overdrive.

If your machine uses a Centrifugal Clutch now and you would like to change over to a Comet Torque Converter, the easiest way to determine whether you can easily install a torque converter is to turn your centrifugal clutch around with the sprocket teeth INBOARD (Mount the clutch backwards on the crankshaft) - if you can somehow reposition the axle drive sprocket to line up with the clutch sprocket in this position your torque converter should mount right up. You may have to slide your axle drive sprocket about an inch closer to the motor to get both sprockets lined up properly.

IMPORTANT! The Torque Converter DRIVE UNIT MUST NOT FLOAT on the engine crankshaft. It must be bolted tight against the engine crankshaft shoulder. Recommended Torque for bolt - 24 ft. lbs. to 30 ft. lbs. Max.

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. The belt when straight in the sheaves should also be square to the engine crankshaft and jackshaft.

The center line of crankshaft and the jackshaft must be parallel at all times.

Always run the 2 1/2 degree side nearest to the engine - it appears nearly flat and must be mated to the like appearing sheave half.

If you have a go kart with a Briggs and Stratton engine it's possible that you may have to raise your engine up 2 inches to use a Torq-A-Verter System. If you have a Tecumseh engine no modifications should be required.
