What is a comet torque converter

The 500 Series torque converter system from Comet Clutches allows peak torque input and downshifts automatically to match load requirements. Clutch changes the ratio between the drive and driven pulleys so that the engine can maintain its peak power output. Drive belt has 0.920 in.

How do I know if my go kart torque converter is bad?

Poor, Sluggish Or Jerky Acceleration (Torque Converter): Unlubricated, loose, or worn drive chain. Binding or dragging brake, bearings or axle. Engine not functioning properly.

Where are Comet clutches made?

Proudly made in the USA, Comet has a global footprint with worldwide customers in the UK, Canada, Mexico, Czech Republic, Sweden, Finland, Japan, Taiwan, Turkey and Switzerland.

How do you measure a comet 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 do you find the gear ratio on a go kart?

To determine your gear ratio, simply divide the rear axle sprocket by the clutch sprocket, so in the case of the above example, 60 divided by 12.

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.

Is a torque converter better than a centrifugal clutch?

Torque converters are great for lower end torque, as they have the ability to adjust the gear ratio depending on the engine’s RPM. … On the other hand, a regular clutch maintains the same gear ratio all the time. This makes it more suitable for lightweight or racing go-karts that are tuned for maximum speed.

How does a comet clutch work?

How does a Comet torque converter work? The drive clutch is activated by the centrifugal force from the engine crankshaft. The moveable sheave of the clutch is forced in as the RM of the engine is increased. … As this happens, the speed from the engine transferred to the final drive is increased.

How do you adjust a torque converter on a go kart?

  1. Step 1 – Remove the Nut, Snap Ring, Cam and Spring. In order to adjust your torque converter, you must get access to the spring. …
  2. Step 2 – Adjust the Spring. …
  3. Step 3 – Reassemble the Nut, Snap Ring, Cam and Spring. …
  4. Step 4 – Preload the Spring and Assemble the Snap Ring and Nut.
Why does my go-kart take off when I start it torque converter?

Over time and through improper maintenance, some torque converters can ‘stick’. When a torque converter sticks, it doesn’t successfully disengage, which causes your go-kart to take off when it’s supposed to idle.

Why is my go-kart losing power?

One of the more common reasons for go-kart acceleration problems is the result of a clogged or damaged carburetor. … As a result, these jets can often get clogged, especially when you haven’t changed your fuel filter in a while, due to impurities in the fuel passing through.

Why does my go-kart want to take off when I start it?

If your go kart takes off by itself when the engine is started, with no one in the drivers seat, that is an indication that the clutch is badly in need of lubrication. Turn the engine off and park the machine up against a tree or fence to prevent it from taking off when you crank the engine again.

What size belt does a 40 Series torque converter take?

40 series, length 33.87″, width 7/8″, used on many Manco karts and most Carter 40 series karts. 12346 Drive belt used on Manco model 710. 40 Series belt 7/8″ wide. Used on Comet 40 / 44 series torque converters, these belts are all 7/8″ wide.

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.

How does centrifugal clutch work?

A centrifugal clutch works, as the name suggests, through centrifugal force. … The rotation of the hub forces the shoes or flyweights outwards until they come into contact with the clutch drum, the friction material transmits the torque from the flyweights to the drum. The drive is then connected.

How many teeth should my go-kart clutch have?

This means for every tooth on the clutch there are six teeth on the rear sprocket. So if you count 10 teeth on the clutch there should be 60 teeth on the rear sprocket. (12 teeth on the clutch means a 72 teeth rear sprocket).

Is a smaller sprocket faster?

Gearing ratio refers to the ratio of rear to front sprockets. … Substituting a larger front or smaller rear sprocket lowers the ratio (sometimes called “taller” gearing), resulting in more speed for a given engine rpm. Likewise, a smaller front or larger rear sprocket gives less speed for a given rpm (“shorter” gearing).

What is a jackshaft on a go-kart?

A go-kart jackshaft is a mechanical component that transfers rotational force between the crankshaft and the axle. In essence, a jackshaft is a long shaft, which actually looks like an axle and is located in between the engine crankshaft and the rear axle.

Which is better torque converter or CVT?

Torque converter transmissions offer big torque at low revs, but are generally less efficient than single and dual-clutch transmissions. … CVTs offer nearly an infinite number of gear ratios, meaning your engine is always working at peak efficiency, regardless of speed.

What is a dry clutch?

What Is A Dry Clutch? … That means less drag and more power going to the rear wheel as well as cleaner engine oil, but it also means less cooling for the clutch pack. Without oil to cool things and damp engagement, dry clutches will act up if you hammer them and they tend to be grabbier and harder to modulate.

At what RPM does a centrifugal clutch engage?

a. A clutch starts to engage around 2,000 rpm and will lock up around 2,600 rpm. Driving at full throttle gives the clutch a chance to cool down. Full throttle locks the shoes in the clutch against the drum.

Does a torque converter make a mini bike faster?

No, putting a heavy torque converter in a mini bike would make it much slower, but if you put a CVT (continuously variable transmission, which, for some strange reason, is sometimes called torque converter), a minibike would accelerate faster but the top speed would be lower because power losses are greater than with …

Does my go kart need a torque converter?

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.

Do you oil a centrifugal clutch?

Your Kart or mini-bike is equipped with a centrifugal clutch that has to be lubricated daily. … Both the clutch and the chain need daily lubrication. The clutch contains an oil impregnated bronze bushing. 15% of the weight of the bushing is the oil that is impregnated into the bushing by the manufacturer.

Why does my go-kart clutch smoke?

When a part of your go-kart is smoking, an investigation into the reason is required before more damage occurs. The most common cause, usually the main culprit, is that the clutch is engaging, but it’s not fully grabbing. It is generally due to the engine not being powerful enough to get through the engagement stage.

Are all go-kart clutches the same?

Go-kart chains come in different sizes and the size requirements depend on the size of your rear sprocket and clutch sprocket. Always ensure that the clutch sprocket and the rear sprocket require the same chain size. You’ll see that in most cases, go-kart clutches are compatible with a #35 chain or #40/41/420 chains.
