TC2 Torque Converter
Asymmetrical System
1001 - GTC TC2 Torque Converter
MSRP: USD$189.00
3/4" Bore, #35P, 12T, 2-7 HP Engines. OEM Comet 218352A TAV2 30-75 Torq-A-Verter for Go Kart or Mini Bike
The TC2 is available in four models A smaller size for 2-7hp engines with a 3/4" Crankshaft and a larger size for 8-13hp engines with a 1" Crankshaft. The TC2 can be ordered for #35 or 40/41 chain size. Engine must have a Drilled and Tapped crankshaft in order to install the TC2. The TC2 is fully compatible with Comet TAV2 Torque Converter with all parts interchangeable.
4 Models: 1001, 1002, 1003, 1004
HIGH PERFORMANCE
The TC2 provides Neutral engagement at Engine Idle. At 2200 RPM, the system engages for a Powerful Low Ratio for great takeoff speed. At Mid Range, the TC2 instantaneously shifts ratios based upon RPM and Load Requirements. Finally, the High Performance Overdrive engages for maximum speed
Neutral .
The Belt is not engaged at idle effectively placing the TC2 in neutral
Low
As the engine throttle is applied, the Driver Pulley begins to engage 2200 RPM. The Drive Belt engages the Driven Pulley at its largest diameter. This is Low Gear position
Mid Range
As the RPMs increase, the Driver Pulley flanges continue to contract forcing the belt to a larger diameter. This action depends upon RPM and Load. If the load is increased, the process is reversed, forcing the belt to a smaller diameter. This process allows the TC2 to raise and lower the ratios as required between high and low.
High Overdrive
At maximum RPM, the Driven Pulley becomes fully open allowing the smallest possible diameter. At the same time, the Driver Pulley flanges are fully closed forcing the belt to its maximum diameter. This is High Gear Overdrive position

TC2 TORQUE CONVERTER KITS TC2 is an OEM replacement for Comet TAV2 30 Series
MODEL 30 SERIES (ASYMMETRICAL) GENERAL INFORMATION: The TC2 30 Series is an asymmetrical torque converter system in which the sheave faces have different angles. The system operates with the torque sensing cam in an outboard position allowing for in-line operation of the unit. The primary benefit of this design is that it allows proper alignment of the final drive chain to be on the same side of the vehicle as the torque converter. Moreover, the angle on the movable sheave being set at 18 degrees enables the unit to raise the belt to a larger pitch diameter with less travel of the sheave. This allows the unit to achieve higher overdrive ratios at maximum rpm

COMET 40 SERIES TORQUE CONVERTERS
TC40 TORQUE CONVERTER SYSTEM TC40 is an OEM replacement for Comet 40 Series
MODEL 40 SERIES (SYMMETRICAL) GENERAL INFORMATION: The model 40 is sometimes referred to as the "Mid-Range" torque converter systems since it falls into the middle range between the TC20, TC30, and 90 or 102 systems for larger horsepower engines. The model 40 is a rugged piece of machinery. The drive clutch is composed of heavy walled stamped steel to withstand the extreme rigors of rough applications. Whenever there is a need, want and use for a torque sensitive drive system device that is infinitely variable form engagement to the highest speeds attainable (within the pitch diameter range), the 40 model system should be considered

TC20 TORQUE CONVERTER SYSTEM TC20 is an OEM replacement for Comet 20 Series
MODEL 20 SERIES (SYMMETRICAL) GENERAL INFORMATION:
The model 20 uses a 3/4" top width belt. The belt mass lends substantially to the driving ability of the system, especially in cases where added torque ability is required without danger of slipping the belt. The belt mass of 3/4" top width is especially helpful in applications of low speed, added power requirements such as tractor mowers, off road dune buggies, mini bikes, ATV's, and go-karts. This is a conventional type system featuring 13° angle sheave faces for a 26° collective angle. Driven units available with either 6" or 7" diameter sheaves

TC340 COMET 340 SERIES TORQUE CONVERTER SYSTEM TC340 is an OEM replacement for Comet 340 Series MODEL 340 SERIES (SYMMETRICAL) GENERAL INFORMATION: The model TC340 automatic torque converter system was designed specifically for light horsepower applications such as mini-bikes and other lightweight sports vehicles as well as industrial applications. Generally engine driven, this converter is of the torque sensitive type in which the vehicle or driven load has influence on establishing the ratio between the driver and driven. In normal operation, the driver “shifts into high” in response to the engine’s increase in speed; the driven follows this speed change as in any variable pitch belt drive. In the torque sensitive design, a cam actuator in the driven reacts to increased torque demands by downshifting without loss of engine r.p.m. In this way, the engine continues to operate at peak power range for all but the most severe loads when it will shift into peak torque range.

TC2 INSTALLATION NOTES: If your engine currently has a Torque Converter installed, you should be
able to install the TC2 without any modifications. If you are converting from a Centrifugal Clutch, you
may need to make some modifications to install your TC2. The Mounting Bracket pictured in these
instructions is supplied with Models 1001 and 1002 for use in engines up to 7hp. Models 1003 and
1004 come with a larger Mounting Bracket (not pictured) for use on 4-13hp engines. The Mounting
Brackets fit many manufacturers engines. The Bracket can be tilted up or down as needed. Some
engines may require relocating minor components to facilitate installation. The Hex Bolts supplied will
fit most engines, however, Manufacturers make changes from time to time and it is not possible to
supply correct hardware to mount the TC2 to all manufacturers engines. Some non-standard and
imported engines may require the use of different size bolts (not supplied). If this is the case, refer to
your engine user guide for bolt dimensions. If this information is not available, then you may have to
test a few bolts to determine the correct size. Notes for the 1" Driver: Does not use a Bronze
Bushing. Be sure the 8-Splined Hub is installed with the key towards the engine
Converting from a Centrifugal Clutch to a TC2
If your machine uses a Centrifugal Clutch now and you would like to change over to a GTC Torque
Converter, the easiest way to determine whether you can easily install a TC2 is to check your
centrifugal clutch with the sprocket teeth in the INBOARD position (in between the engine and clutch).
If the axle drive sprocket lines 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 - 14 ft. lbs.
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.
Some engines may require that you raise your engine up 1 or 2 inches to use a Torque Converter
System.
