What is a 30 Series torque converter? Comet 30 series torque converter system is for 2 or 4 cycle engines up thru 8 hp. The model 30 uses a 3/4″ top width asymmetric belt. Drive clutches are available for both 3/4″ and 1″ bore (with 3/16-1/4 keyway). Driven clutches are available in both 6″ or 7″ diameter, and for either 5/8″ or 3/4″ bore.
What is a 40 Series torque converter? Comet 40 Series and Comet 44 Series are Mid Range Torque Converter Components for 8 to 18 horsepower applications. The 40 Series Driver Clutch fits 1″ engine crankshafts with a 1/4″ keyway. The 44 Series Driver Clutch is available for 3/4″ crankshafts with a 3/16″ keyway and 1″ crankshafts with a 1/4″ keyway.
What size torque converter do I need for my go kart? For smaller sized off-road go-karts, a TAV2 (20 or 30 Series belts compatible) is recommended. They’re compact and should suffice. If you own a larger off-road go-kart it’s highly recommended to use a larger torque converter, that supports a 40 Series belt.
How do I know what series torque converter I have? Identify the Shape. A V shaped belt indicates the unit is a TC88, 20, 40 or 44 Series – SYMMETRICAL Type. If the angles of each side of the belt are different, almost flat on one side – 2 1/2 degrees and angled 18 degrees on the other side, you have a 30 Series or an older CAT99 Series – ASYMMETRICAL Type.
What is a 30 Series torque converter? – Related Questions
Is a torque converter better than a centrifugal clutch?
As torque converters handle low torque ranges more easily, they’re most commonly used on off-road go-karts. They perform better at lower speeds and are ideal for stop-and-go situations. Clutches on the other hand are snappier and perform better at high speeds.
How do you measure a torque converter belt?
Simply take a measuring tape and hold it against the outer plate of the pulley. Measure from one side of the plate to the opposite side. If you’re running a standard torque converter the diameter will either be 6-inches, 7-inches, 7.5-inches or 8.5-inches.
How much horsepower can a 30 Series torque converter handle?
Comet 30 Series Torque Converter System (Asymmetrical)
Comet 30 series torque converter system is for 2 or 4 cycle engines up thru 8 hp. The model 30 uses a 3/4″ top width asymmetric belt. Drive clutches are available for both 3/4″ and 1″ bore (with 3/16-1/4 keyway).
Does my go kart need a torque converter?
Go Karts with rear tires taller than 15″ or an engine larger than 8hp require a torque converter. BMI Karts and Parts has all the go kart clutches to gear up with!
What is the difference between a torque converter and a clutch?
The main differences between centrifugal clutches and torque converters are: Centrifugal clutches connect the engine to the transmission, while torque converters allow the engine and transmission to run independently from one another.
What is the difference between a 30 and 40 series clutch?
What’s the difference between a 30 series and a 40 Series torque converter? Actually you have it backwards, the 30 is asymmetrical(one side of belt/pulleys is flat), 40 is symmetrical(V belt). So long as it fits the engine and fits in the cart you are good to go.
How long is a 40 Series torque converter belt?
40 series, length 33.87″, width 7/8″, used on many Manco karts and most Carter 40 series karts.
Which is better torque converter or CVT?
Modern automatics offer better fuel economy than manuals, thanks to a larger choice of drive ratios. Modern twin-clutch systems use seven gears, torque-converter autos are pushing as high as nine and CVTs can produce a near-infinite number of ratios, meaning they offer the best fuel economy.
What does a torque converter do on a Predator 212?
A torque converter acts similar to a transmission, allows higher speeds out of your small engine, and smoother acceleration. Our torque converter fits a 3/4″ shaft and comes with a 10 tooth sprocket for a 40/41 chain or a 12 tooth sprocket for a 35 chain.
What is the best gear ratio for a go kart?
To determine the gear ratio necessary for your go kart or mini bike you must know the limit of your top speed. When using a clutch to drive your go kart the top speed on flat terrain is 35mph, if the terrain is hilly or the weight of the driver is high the top speed should be 25mph.
Why does my go kart torque converter slip?
If you install a torque converter belt on your go-kart that is incorrectly sized, you’ll encounter unique problems depending on if the belt is too short or too long. A belt that is too long can also lead to slipping because there is a lack of tension on the belt between the two pulleys.
What size is a 30 Series torque converter belt?
3/4″ Belts, flat on one side, angled on the other. 30 Series has a Green Tension Spring in the Pulley. 20 and 30 Series Pulleys BOTH have a #20 Stamp.
What do the numbers on a CVT belt mean?
CVT belts are measured in 3 dimensions. For example, here is what the numbers of a 669-80-30 belt actually mean: 669 = The Pitch Length of the belt in millimeters. 18 = The Width of the belt in millimeters. 30 = The Angle of the teeth on the interior of the belt.
Does a torque converter make a mini bike faster?
Torque converters will have heavy torque as to move heavier loads slowly at first. RPM’s will start high, as speed picks up the adjustable pulley will gain speed quickly. They can be faster than a regular centrifugal clutch as the pulleys’ adjust to max belt ratio. I have one on a large 4 tire kart.
Why do mini bikes have torque converters?
A torque converter acts similar to a transmission, allows higher speeds of your small engine, and smoother acceleration. Small engine Torque Converter clutches are mostly used in go karts and mini bikes.
How does a torque convertor work?
The torque converter casing connects to the flywheel, spinning at the same rate as the crankshaft, within the housing of the turbine. The impeller or centrifugal pump effectively flings the transmission fluid into the fins of the turbine that in turn spins or transmits the torque into the transmission.
Why does my go kart keep dying?
The most common culprits are a closed choke, a dirty air filter, a clogged carburetor or leaking fuel lines. If your go-kart dies when hitting the gas pedal, there are several quick fixes which can help you solve this problem.
How do you get more torque on a go kart?
Lowering timing will increase torque at lower RPM but if you go too low it may hurt you on top end. Clutch engagement will make a huge difference in low end power.
What does a CVT use instead of a torque converter?
CVTs without a torque converter are typically driven through a dual mass flywheel or a torsional damper plate that connects the crankshaft to the input shaft.
How fast will my go kart go?
Most karts max out around 40-50mph, while this is a maintained speed that is safe and as controlled as you can be. It’s a speed that is comfortable in the sense of you wont fly off the track, and hurt other racers or patrons. At LVGP ours max out at around 45mph.
Do torque converters wear out?
Torque converter seals can be damaged easily or get worn out with time, so they are a common source of transmission fluid leaks.
