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 ratioof standard systems. The TAV2 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.
| Neutral | Low Range |

| The asymmetric belt has no engagement during the idling of the engine. The system is Neutral--with no belt friction and no drag. | As the engine throttle is opened the Driver pulley flanges begin closing together via centrifugal force. The Drive Belt engages, driving the Driven unit pulley at it's largest diameter. This is the most powerful ratio of the system. |
| Intermediate Range | High Range-Overdrive |
 |
 |
| As the engine R.P.M. increases, the Driver pulley flanges continue to close together. This action, in turn, is squeezing the belt out to a larger Driver unit diameter. This action is dependent on acceleration and lack of torque load on the Driven element, allowing its pulley flanges to open thus creating a smaller driven unit diameter. If the torque load is increased this ratio is reversed instantly and smoothly to its requirement. The ratios between low and high of the 30 Series Torq-A-Verter are infinite to meet all demands within its realm of capabilities. | At it's highest speed (overdrive) and lowest load demand, the Driven unit pulley flanges are wide open providing the smallest possible belt contact diameter. The Drive unit pulley flanges, at this point, are closed to provide the largest possible belt contact diameter. The unique asymmetric arrangement of the belt and pulley angles allow the belt to exceed diameters possible with the standard "V" pulleys, thus overdrive. |

| Extend the life of your equipment merely by regularly freeing it of belt residue and belt dust. 11 oz Spray Can. Comet GP-730A dry-film lubricant is super stuff for your Comet torque converter. Don't let your equipment get "All Gummed Up!" or excessive parts wear will result. Can not be shipped UPS Next Day or 2nd Day Air. | |||
GP-730A is specially formulated for the unusual requirements of torque converter systems operating in dusty-dirty-sandy situations. GP-703A bonds to the surface being sprayed within one to two minutes or less in normal air-drying conditions. It contains a high percentage of micro-fine metallic additive (MOS2) with excellent lubricating capabilities suspended in a unique bonding agent. It will not "dust away" or dislodge and bonding occurs without heating or baking. Even under sliding pressure it actually bonds to most ferrous and non-ferrous metals as well as to plastics, fibrous, wood, glass, rubber and many other friction surfaces. It greatly enhances effectiveness of normal lubricants applied over it. It's non-corrosive, inert to water, oil and many acids, solvents and alkalis. It contains no oil, grease, wax or silicone; it will not attract dust or dirt. GP-730A greatly lowers metal to metal contact and thus reduces power consumption and torque loss.
Belt driven torque converter driver and driven clutches found in current day snowmobiles, ATV's, mini bikes, utility vehicles, go karts, etc., like most mechanical devices require a schedule of regular preventative maintenance; this includes CLEANING and RE-LUBRICATION. Equipment operated in DUSTY, MUDDY, or SANDY conditions need more intensive care and frequent lubrication . . . maybe even after every use, depending on the application. Clutch and driven units, even if not exposed to such extreme conditions, still require a lubrication that will perform reliably without "breaking down", one that will not "sling away", one that will withstand the many thousands of pounds per square inch of the centrifugal and torque pressure and one that will perform equally well on a variety of friction surfaces such as the plastic guide buttons, steel rollers and pins, steel ramps and counter weights, fiber and metal bushings, etc. The wear problems frequently attendant in this type of equipment are compounded by any lubricant capable of attracting dust, dirt , sand, etc. Even belt dust and metal particles resulting from the driver clutch and driven units' own wear will be trapped and accumulated in any kind of moist lubricant including oils, grease, anti-seizing compounds and the popular lubrication/water-displacing agents supposedly dry, but actually leave a "waxy" residue. Use of any such lubricant tends to trap this foreign matter, resulting in formation of a "cutting compound" type of abrasive action as well as a sticking and gumming action. A genuine dry lubricant will prevent this while increasing operating efficiency and part life too.
Temperature Service Range: -300 degrees F (-184 C) to + 700 degrees F (+371 C)
A nozzle extension tube is provided with can for concentrating and focusing the spray and reducing waste.
