how do i adjust a centrafugal clutch?

Question

I have a manco go cart and drive on grass and dirt. Once warmed up the tires spin too quick not allowing go cart to go. Is there an adjustment to the clutch? I was going to put different tires but will have to expand the shaft, thus not desireable

Answer 1

There are a couple of adjustments that you can make to a centrifugal clutch. The biggest adjustment is the centrifugal weights in the clutch. Depending on the manufacturer of the clutch, you can buy different sized and shape weights to tailor your clutch to your specific needs, such as engagement RPMs, how fast the clutch is completely engaged, Max RPM's etc. These clutches also have a return spring that determines how fast the clutch disengages. There is almost an infinite amount of adjustments you can make in the clutch. You may be able to get directly in touch with the clutch manufacturer for tech help (they often have catalogs and tech support lines), or possibly get some info from a local snowmobile shop (if you live in snow country!) or you can do some experimentation on your own. HTH, Good Luck!!

Answer 2

If you look at any centrifugal clutch, you will see that most does not have any adjustment. The rate at which the weights expand to the drum determines how quick, and how hard the clutch comes in. Is your motor running too fast? Are you accelerating too fast and making the clutch come in too quick? It should not be pulling at all at idle speed, and comes in slowly as the accelerator is depressed. Look for weights on the clutch that can be moved by loosening a locking screw, and relocating them towards or away from the shaft. Some clutches are adjustable by moving these weights, thus changing the rate the clutch activates. You have already determined if it spins it makes the clutch come in quickly and will kill the engine. You are correct in thinking about the tire size. Going to a taller tire will make the problem worse, and going to a shorter tire will make it spin more easily, but will keep it from stalling the engine. It will also take away from the top end speed of the cart. You could try changing the ratio of the drive sprocket and achieve the same thing by going to a smaller one. Sounds like the tires are too tall! Either use a smaller tire, or change the ratio of the drive sprocket should fix the problem. If you adjust the clutch, it will only add slippage to the clutch, and cause the clutch to burn out quicker than you may want. Good Luck!

Answer 3

The simplest way to solve this problem is weight. Take the valve stems out of the rear tires and get a tube and funnel and put some antifrezze in your tires up to the valve stems. If that is not enough put some weight on the rear of the frame this is the cheapest fix to that problem.

Answer 4

maximum motorcycles would be distinctive except they are new. With the grasp lever no longer pulled in, the freeplay must be 2-4mm on the lever's pinch element as we start to stick to tension on it. over the years the grasp plates positioned on and your cable stretches. maximum cables have 3 adjustment factors. One up on the lever, one on the grasp conceal/case and in some cases one is located halfway alongside the cable's length.

Answer 5

the belt is to tight no adjustment on a centrifugal clutch

Answer 6

Adjust the governor.

Answer 7

nope, its working well you could try to let a little air out of the tires as it will give it a bigger foot print

Answer 8

check with a mechanic and maybe he can give you some advise, good luck

I don't believe so
