Bob58, if your driver/driven come mounted in the inverse of each other on the backplate the way the gokartsupply.com diagram shows they should be, you're good to go. You can think of the part number as an SKU (Stock-Keeping Unit) number. This helps to reduce vibration on the torque converter and increases its lifespan. Each belt model or series has a subset of belts with different dimensions. Any aftermarket TAV2 (30 Series belts) would be a good choice, as theyre compatible with almost any type of go-kart engine. Frame Tie Rods Torque Converter 30 Series Torque Converter (TAV2) The model 30 is mounted with both stationary sheaves inboard. Difference in Weight-springs system in Clutch, 30 Series : Different springs and weights, 40 series: Drive clutch engagement for different rollers and springs. It also comes with two sprockets. If used on engines larger than 18 HP, you will burn up belts. To check belt and torque converter compatibility, you can use the belt size chart. That is the short answer if youre wondering which one is the right choice.

If youve decided to get a new torque converter for your go-kart or mini bike, youre likely trying to decide between the 30 and 40 series. The driven units can come in different diameters and you can change them to your liking to get higher or lower speed reduction ratios, do keep in mind though, if you change the diameter of the driven, youll also need to change the belt. I was really hoping to keep it as stock as possible! This "New Generation" torque converter is available for General Motors, Ford and Chrysler transmissions. Hey Rob, thanks for getting in touch. It provides smooth acceleration and reduces the engine load. It can easily adapt according to the engines rpm and has the ability to dynamically change the gear ratio. Basically, you make the spring stiffer for getting more power out of your engine at a particular speed reduction ratio. Ive corrected it! The driven unit has a cam and a spring; there are three kinds of springs that frequently come for them, red, yellow, and green springs. If you have an existing belt that you want to use, youll need to check that the measurements of the belt are compatible with the torque converter. They provide a variable gear ratio and are therefore ideal for lower-speeds, heavy stop-and-go situations or climbing uneven terrain. increases, the Driver pulley flanges continue to close together. With the backplate kits, I believe you need to mount the driver unit inboard, since you cant mount the driven unit inboard. Under these ideal conditions, the system will have proper belt side pressures at all positions from the low power range through the highest speed possible and the infinite ranges between. This means that the pulley and belt system will create a lot of heat, as the crankshaft spins. So the top combo will be ninety-gram weights with the orange spring. They have a spring loaded cam that will respond to the torque load demand of the driven shaft to adjust the ratio of the system for the power required. The best go-kart torque converters in this list come with a compatible belt (30 or 40 Series). 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. . Low End Ratio is the ratio between the drive clutch and driven unit when the drive clutch is at its smallest pitch diameter and driven unit is at its largest. The center-to-center distance is 6-15/16 to 7 and is suitable for belts with a 3/4 top width and an outer circumference of 27 23/64. What torque converter should I use?

Likely if youre to go with the 30 series, you have a smaller engine such as the predator 212, the best spring-weight system is the one that engages at an RPM at which your engine produces maximum torque. In a broader sense, the over-all ratio of the drive train also includes the sprocket or gear ratio and is determined by multiplying these separate ratios each times the other. Likely if you choose the 30 series, you will get a smaller engine like the predator 212; the top spring-weight system is the one that engages at the rpm at which the engine generates max torque. Conversely, the latter would travel more quickly though it could not handle as great a load or as difficult a terrain. (5) that the drive belt have the correct outside circumference and proper top width. and Function Episode 4 In this episode of our ongoing Torque Converter 101 series, we go a bit more in-depth in our discussion of torque .

With a belt that is too long, the drive system loses its low end power ratios due to belt slippage and its high end ratios because the belt cannot be pulled down into high speed pitch daimeters. No welding is required, only assembling the parts. Do you have a belt that would fit? Jugg-A-Verter is a complete CVT or Torque Converter Assembly that features the Juggernaut Super 30 Driver. Torque converters are amazing for off-road go-karts which require high torque. You should make sure that it has at least two pulleys, a belt and the required hardware for mounting. The model name indicates a series of a particular brand. A V shaped belt indicates the unit is a TC88, 20, 40 or 44 Series - SYMMETRICAL Type. It depends on the engine design, but most of them are compatible with go-kart engines from brands such as: For a standard TAV2 equivalent torque converter that is compatible with a 30 Series belt, the gear ratio usually starts around 2.7 : 1. If you make the clutch engage when the engine is producing the most torque you get a good take-off and can do wheelies. The moveable sheave of the driven unit is forced out, as shown, allowing the belt to seek its smaller, high speed ratio diameter. Disclaimer: The information featured in this article is based on our best estimates of pricing, package details, contract stipulations, and service available at the time of writing. 4-3/4driven 6 and c to c 6-5/8.
