# How do you measure a torque converter belt?

Torque converter belt measurement. When selecting a belt for a torque converter, the outside diameter of the belt is not the best way to measure. Take a measurement from the centerline of the crankshaft to the centerline of the rear driven pulley’s shaft. This measurement needs to be within 1/16″!

Measure the “Outer Diameter” (O.D.) of the driven pulley on the jackshaft. 3. Measure the “Center Distance”; which is the exact distance between the center of the engine crankshaft and the center of the jackshaft or secondary shaft.

Also Know, how do I know if I have a comet torque converter? 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.

Also question is, what’s the difference between 30 and 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.

What size torque converter do I need for my go kart?

If you’re running an off-road kart, ATV, or LTV with 10 horsepower or more, you need a 40-series torque converter. These are rated for 8 horsepower minimum and 25 horsepower maximum. The 40-series torque converters have a 1:1 final drive ratio. Drive clutches are available for 3/4″, 1″, and 1-1/8″ diameters.

### What is the difference between a clutch and a torque converter?

Simply put, a torque converter is the clutch of a car with an automatic transmission. Unlike a manual clutch, it uses fluid to transmit power to the transmission, and for this reason, it prevents engine stalling and allows the transmission to easily change gears on its own.

### Does my go kart need a torque converter?

Clutch. In summary, a go kart torque converter is ideal for rough and off-road terrain where there are obstacles to be avoided or crossed and uphill driving may be required. But if your goal is to achieve the maximum speed to race in the pavement, a clutch is the better choice.

### How does a belt drive clutch work?

It works only when acted upon by the force of the drive belt. As the engine spins, thus forcing the belt to ride higher on the drive clutch, the belt, in turn, forces the driven clutch sheaves to separate, allowing the belt to ride closer to the center shaft of the driven unit.

### What does a torque converter do?

In brief, the torque converter is a type of fluid coupling, which allows the engine to spin somewhat independently of the transmission. It is responsible for pressurizing automatic transmission fluid, a pressurization that supplies the force necessary to shift transmission gears.

### How do you measure a motor belt?

Measure and record the distance between the motor shaft and the pulley shaft, and then measure the diameter of the motor pulley (also called the drive pulley or sheave) and the fan pulley (called the driven pulley). So, select a new belt the next length above 43 inches. Next, determine the thickness of the belt.

### Where is centrifugal clutch used?

Centrifugal clutches, which use centrifugal force to convey a movement correctly, are primarily applied to industrial machineries such as sweepers, mowers, chainsaws, generator sets, motor pumps, lawn mowers or fans. Moreover, they are also applied to refrigeration systems and mini-karts.

### Can you rebuild a torque converter?

Repair shops will charge between \$600 and \$1000 to replace a torque converter. The torque converter itself is relatively inexpensive (between \$150 and \$350, depending on the vehicle), but 5-10 hours of labor is involved since the transmission must be removed in order to replace the torque converter.

### 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.

### How does a Go Kart transmission work?

Transmission means the whole of mechanism that transmits the power from engine crankshaft to the rear wheels. In Go kart vehicle, the power from engine is transmitted to the sprocket using chain i.e. chain drive. Usually Go karts do not have a differential, so it is eliminated.

### How do you recognize a comet?

Comet: A body of ice, rock and dust that can be several miles in diameter and orbits the sun. Debris from comets is the source of many meteoroids. Meteoroid: A small rocky or metal object, usually between the size of a grain of sand or a boulder, that orbits the sun.
