Go Kart With Manual Clutch

The 3D manual clutch (Patent Pending) is a cable operated bolt-on unit that takes minutes to install and will immediately increase the performance of your mini bike or go kart. Simply add a clutch lever to your handlebars or steering wheel and you will be able to control clutch actuation just as you would on a motorcycle or in a car. If you want to increase performance using state-of-the-art technology, the 3D manual clutch is an absolute must have. To learn more about the many advantages this clutch has to offer, click here: 3D Manual Clutch Product Page The locking button makes it possible to start the bike up and walk away from it during engine warm up. Our ultimate priority is to ensure that our customers are completely satisfied with their 3D Manual. The rider must only know how to control the throttle in order to get the kart or bike moving since the clutch is controlled by the engine speed and not by a lever or pedal. This is where the advantages stop and the disadvantages begin. To name a few: This is for two reasons. First, almost all non-racing clutch manufacturers design their clutch to engage just above idle in order to improve ride-ability at low speeds. The engine makes little torque at this low RPM which correlates to poor acceleration. Second, engines equipped with centrifugal clutches are unable to use the energy stored in the flywheel and other rotating engine components to propel the vehicle off the line. Some very expensive racing clutches (Bully, SMC, Jammer, etc.) enable the engagement speed to be adjusted to match the RPM that the engine achieves peak torque. This improves acceleration, but still does not allow the rotating inertia of the flywheel to be utilized to propel the vehicle forward. Decompression braking is used throughout motorsport to help set up for turns and to also keep the engine at elevated RPM in preparation for the transition back to the throttle.

On race engines that do not have a pull start, this means buying an expensive remote starter to start the engine. For motorized bicycle enthusiasts, a centrifugal clutch prevents the rider from pedaling to start the engine. If the vehicle is moving so slow that the clutch has to be disengaged to maintain the speed, the clutch can burn up as a result of the heat that builds up during slippage. This is especially true for race karts that have clutches with high stall speeds. Race karts can only be driven below race pace for short periods of time, else they risk permanent clutch damage. In fact, no other modification will improve the performance as profoundly and cheaply as the 3D Manual Clutch. Some of the primary advantages are: The laws of physics dictate that maximum acceleration occurs when maximum torque is applied to the rear wheel(s). Maximum torque is applied to the rear wheels when the engine is at the RPM that peak torque is made. A manual clutch is the device that allows the rider to hold the engine at peak torque while accelerating via precise control of the clutch lever. Additionally, a manual clutch allows the rider to convert the energy stored in the flywheel into usable torque for a burst of acceleration off the line and out of turns. Put simply, for off the line acceleration, there is no faster clutch on the market. The rider can now elect to start the engine by pushing the bike forward with the clutch disengaged and then quickly releasing the clutch lever. This is a major advantage for motorized bicycle enthusiasts because it allows the pull start to be removed if desired. With proper clutch technique, rear wheel traction can be improved in and out of turns. This is a significant advantage for race kart drivers. If you love wheelies, burnouts, and donuts, and want your mini bike to feel like your dirt bike then you will love using the 3D Manual Clutch. It clamps to the steering tube, comes with cable adjuster, and rubber dust seal.

Using any other lever may or may not cause averse effects to the performance and usability of the clutch. Please choose the appropriate cable housing length for your application.

The SS series is the most popular style clutch used by the O.E.M. since its introduction in 1970. The following instructions will help you do just that.By adjusting the spring pressure as shown in Figure 3, it is possible to get more or less RPM (slip) as needed. This step is an absolute must. The correct lapping compound for this operation has been included with your clutch. Make sure the spark plug is in place to keep the crankshaft from turning. (Hold crankshaft with taper plier jaws if necessary). Apply a small amount of compound to the taper on the crankshaft, then place the tapered hub over the end of the crankshaft and push and twist, first clockwise then counterclockwise, then lift, rotate the clutch and push and turn some more. Continue until both surfaces are 100% seated.

After the lapping is completed, clean up all traces of the compound from both surfaces. Due to manufacturing tolerances it is possible that the crankshaft key may be too tall to allow the clutch hub to fully seat on the taper of the crankshaft. If you find this condition, file some material off of the top of the key until the clutch seats properly. The disc ears must be aligned with the small grooves in the drum. Using red loctite, install the starter nut and tighten to about 25 foot pounds.It is important that there be some clearance, too much is better than not enough. Grind the spacer if necessary, or replace it with another one of the correct size. If any binding occurs repeat Step 9. When the oil is at the correct level, replace the plug. Depending on the type of third bearing support, it may be necessary to cut or notch it to get at the filler plug. Check the clearance between the filler plug and third bearing support and add spacers if necessary (Figure 4). At the same time watch the movement of the nut through the holes in the spring cup. Run the clutch at the one turn setting for 3 to 5 laps. If your kart is equipped with a tachometer, you may want to make an adjustment if necessary, after the breakin period to get the exact RPM needed. To get more slip, the spring preload must be increased.Any more than that will damage the springs.The correct clearance is 0.030 to 0.035. If the friction disc becomes worn and the air gap gets over 0.035, shims can be installed as per Figure 6 to maintain the correct air gap. To install the shim, squeeze the flywheel and pressure plate together with a pair of pliers and slide the shim into place. Make sure that the head of the shim is towards the inside of the clutch, otherwise centrifugal force will pull them out of place. After inserting the shims in each lever strap, look at the weights and lever strap pins to make sure that they are in the right position.

The weights must be against the lip of the flywheel and the pins must be all the way up into the lever strap hole (Figure 7). You must change the oil when your day is over. It may be necessary to tip the kart on its side to get out all the old oil if the cover is not removed. See Figure 5 2. Lubricate the chain. A special tool is needed to take the clutch apart and to put it back together. This tool is available from the dealer that sold you your clutch. If warpage exceeds 0.010, replace pressure plate. If they measure less than 0.085, they should be replaced. Created with Sketch. We carry quality go kart clutches for most makes of go karts including Yerf-dog, Manco, Brister, Carter, and more.

Centrifugal Clutch Bushings and Sprockets. We also stock Centrifugal Pulley Clutches, Go Kart Clutch Keys, Keystock, Rebuild Kits and Set Screws. The key and optional set screws are included. The secret to it's success is the ability to take heat without ruining the garter spring. The spring is made from 302 stainless steel and it can take more than twice the heat of music wire used by competitors. Grease the engine crankshaft and tapped hole for easy removal in the future. Max-Torque Clutches are designed, engineered and manufactured to deliver exceptional performance. They're unique and original in design and engineering. Others have copied the design, but they're not able to duplicate the performance and reliability engineered into the Max-Torque Clutch. It's exclusive ground sleeve provides a 10 microfinish for smoother bushing contact, less friction and extended life. The stainless steel spring can't rust, assuring more consistent application of shoe pressure. These plus other Max-Torque pioneered features provide the quality Original Equipment Manufacturers (OEM) specify.and you demand. Minimum operating controls, the throttle becomes the single control for engaging or disengaging the power, as well as controlling the operating speed. Speed up the engine and engage the drive train - slow down the engine and it disengages - one control, the throttle does it all.

The standard Max-Torque SS automatic clutch uses six sintered metal clutch shoes. The shoes evenly distribute the centrifugal loading force over 345 degrees of the drum circumference which lessens drum distortion. The smooth non-aggressive engagement action approximates that of an automatic transmission. It's Preset to engage at approximately 2,200 rpm. This protects the operator, as well as the power transmission system during engine cranking, starting and idling. In the event of an overload, the engine will be lugged down to a slower speed, which will automatically disengage the clutch. Once the overload condition has been eliminated, the clutch will reengage and operate normally. Clockwise or Counterclockwise Installation. It will operate with equal efficiency in either a clockwise or counterclockwise rotation. The clutch can be mounted inboard or outboard with no adjustments needed. It maintains it's appearance. The drum and sprocket have a black oxide finish while the drive and shoe retainer plates are zinc plated. The oil impregnated bronze bushing rotates on a ground sleeve. This configuration, utilizing a high-grade specially formulated oil or grease for bushing lubrication, considerably increases clutch life in high heat conditions over assemblies that use needle bearings. It can be completely disassembled with snap ring pliers to replace any worn or damaged parts. It works in contamination. The use of sintered metal shoes and a stainless steel garter spring enables the Max-Torque clutch to maintain its efficiency even when contaminated with dirt, oil, or water.They fit inside the clutch, not directly on the engine crankshaft.Clutch made in China. The 12 Tooth Clutch uses 35 Chain. The 10 Tooth Clutch uses 40, 41, 420 Chain. This lube system supplies lubrication directly to the clutch bushing through the keyway of the engine crankshaft utilizing a special zerkbolt fitting which is available only from Max-Torque.

Since its introduction in 1992, lubrication problems have been dramatically reduced. If your engine does not have this hole, the MAX-LUBE clutch can not be used. Installation Instructions: Remove the old clutch from the engine crankshaft. Disconnect the spark plug lead and slowly pull the starter handle until the crankshaft keyway is facing upward. As shown in the diagram, the width of a nickel will also provide this dimension. Once this point is located use the center punch with a firm hit to make an indentation in the center of the crankshaft keyway. Place the two fibre washers onto the crankshaft, slide the clutch on the crankshaft and secure the clutch with the zerkbolt and washer. CAUTION: Do not over-tighten the zerkbolt as the hex head will snap off. Using a grease gun give the zerkbolt a full pump of grease. Replace the chain on the clutch sprocket and replace the chain guard. Other Operating and Use Instructions: Grease the Zerkbolt, with one squirt, after each week of operation. Avoid or eliminate incorrect gearing. The gear ratio between the clutch sprocket and the drive sprocket should be 1 to 6. For example, if your kart has a 12 tooth clutch sprocket the drive sprocket should have 72 teeth. A 10 tooth clutch sprocket would require a 60 tooth drive sprocket. Tires with a diameter exceeding 15 inches tall should not be used. If any of these suggestions are not followed, the clutch will not operate properly and clutch life will be significantly reduced. This clutch was designed to be a low-cost upgrade to the stock unit. A thermodynamically designed clutch shoe increases the clutches capacity to absorb heat without damaging the clutch springs, resulting in longer life and better reliability. All LD4S Series Clutches are loose assemblies and need to be assembled properly to allow the clutch to operate safely. These steps need to be followed to ensure proper installation. Install a bolt and washer on the end of the engine crankshaft.

On this LD4S-L long bushing series clutch there is a retaining ring to retain the bronze bearing in the sprocket drum. A bolt and washer are used to retain the hub on the crankshaft. While tightening the bolt be sure to torque the bolt to the engine manufacturers specifications. To tighten the bolt you will need to make sure that the ignition is in the off position, to ensure that the engine won't start. Next, get the bolt tight to the point that you are turning over the motor while tightening the bolt. Then MAKE sure the ignition is off, and pull the pull starter just out far enough to catch the motor. Then continue to tighten the bolt to the proper specification, holding the pull starter out, you will feel the engine want to pull the started cord back in, you need to hold it out until you get the bolt tight. For cases where there is no pull starter, you will need to find a way to stop the crankshaft from turning over. Verify proper alignment of the sprockets and install the chain according to your owners manual. Over tightening the chain or having the chain too slack will cause premature sprocket and bushing wear. Oil the clutch bushing every 4 hours of use. Try to get the oil in between the housing and the bushing. Removal of the bushing from the sprocket is the best way to ensure proper lubrication. Requires a tapped engine crankshaft so you can screw a bolt into the end of the shaft to hold the clutch on. The Extreme Duty Sprocket Centrifugal Clutch is ideal for the everyday demands of go karts and youth model snowmobiles. It has been engineered to provide long service life even in the most demanding applications. This Extreme Duty centrifugal clutch can handle higher temperatures to offer longer life. Bi-Directional, they can run clockwise or counter clockwise. Disapates heat better, extending clutch life. Built in internal key. The 12 Tooth Clutch Sprockets use 35 Chain only. Performs clockwise or counter clockwise.

Trade-off is a loss of low-end acceleration. Made in China. For crankshafts, jackshafts, pulleys, axles. You'll have to oil the clutch even more often if you have small children, riding in a small area, never going fast enough to engage the clutch all the way. The clutch continues to generate heat until it engages. Oiling the clutch is extremely important. If heat damage occurs, the clutch will never disengage and the machine will start taking off by itself as soon as you start the engine. This is very dangerous. You can see heat damage inside the clutch drum, the metal turns from black to a blue color. The clutch must be replaced if it has heat damage and won't disengage. Heat damage is never covered by warranty. Where do you oil the clutch. Behind the snap ring, next to the sprocket teeth at the end of the clutch. There's an internal bronze bushing behind the snap ring that requires lubrication and it's up to you to put it there each time. With the engine off, squirt several drops of oil behind the snapring while the bushing is warm. You can also oil the clutch before you ride, oil the clutch and give the oil a few mintues to penetrate down into the bushing. If you don't give the oil time to get down onto the bushing, the oil will just fling off, which is the same as not oiling it at all because the oil never reaches the bushing at all. What oil should I use. A good automotive oil like 10W30 or a straight 30 weight oil is perfect. It's a good idea to oil the chain at the same time. If the chain gets kinky from lack of oil it should be replaced before it damages the clutch sprocket. A new chain is cheaper than a new clutch. The clutch is an automatic transmission that is activated by the increased rpm of the engine. The clutch should not engage when the kart is at idle. The engine manufacturer sets the idle speed of an engine at the factory. There are several things that can cause the clutch to engage at idle.

Because the kart manufacturer does not start each kart after assembly, it's important that the dealer or the kart owner take a couple of minutes to read the owner's manual and review the recommended procedure when starting or servicing a new kart. Throttle linkage can bend while riding or in transit to the dealer. It is highly recommended to always start the go kart with the rider sitting in the drivers seat with his or her foot on the brake pedal. Make sure they know which foot pedal, the one on the left, is the brake versus the gas pedal. Once in the kart, you can roll it backwards with your hand or foot to get the kart in a position to drive forward. During assembly at the kart factory it's possible that too much tension was placed on the throttle linkage causing the engine to idle above 2,000 rpm (the starting speed of the clutch for engagement). Think and stress safety. When you start the go-kart, be in a position where you can shut it off if the clutch wants to engage by itself. Most karts have two shut off switches on them, one on the steering column or steering wheel and the other on the engine itself. Another possibility is to pull off the spark plug wire, which might give you a slight shock. A Tachometer (available on our Tools Page) can be used on the engine to verify just where the engine idle speed is set. You can't verify the correct rpm by listening to the engine and concluding it is too high or too low. Driving at full throttle gives the clutch a chance to cool down. Full throttle locks the shoes in the clutch against the drum. When the clutch is not locked up, the shoes slip against the drum causing tremendous heat which dries up the lubrication in the oil impregnated bushing. The tremendous amount of heat generated can also anneal the spring which is the heart of the clutch. If the shoes turn purple from excessive heat more than likely the clutch is ruined and the spring no longer has the ability to pull back the shoes at idle.

Short stop and go driving: The longer you drive at full throttle the better off it is for the clutch, because it gives it a chance to cool off before the next engagement. Driving with the foot on the brake: This is a problem with new drivers that are unsure of themselves. When riding a go kart for the first time, try to find an open area that has no obstacles that you have to maneuver around until you get used to the brake and gas pedals. The driver must first be able to build up his or her confidence on the kart before putting obstacles in their path. A small back yard is not a good place to learn to drive a go kart. In my opinion, a minimum of three fourths of an acre is the amount of yard needed for a go kart. Teach your child to drive with one foot on the pedal, be it the brake or the gas but not to press on both pedals at the same time. You either want to go or to stop but you cannot do them both at the same time. Changing the size of the tires: Putting on tires that are larger than what came with the kart will result in clutch problems. Tires exceeding 13 inches in diameter stress out a clutch if the kart is not properly geared for the larger tires. If you are driving on smooth flat terrain than you may be able to get by with 15 inch tires but once you get on hilly terrain, deep grass, then you are putting additional strain on the clutch, which will cause premature wear. Big tires look cool on a go kart but you create your own problem changing to bigger tires when the clutch isn't designed to handle them. Weight: A centrifugal clutch is designed to be able to move a certain amount of weight. Once the weight limit is exceeded, then the life of the clutch will be shortened. A good rule of thumb is the kart and driver (and passenger when it is a two seat kart) should not exceed 400 pounds. The kart weighs around 150 pounds add to this the driver (and passenger weight, if it is a two seater kart).

If you know ahead of time that you will exceed the 400 pounds then buy a torque converter go kart and avoid the problems of burning up the clutch asking it to do more than it was designed for. Gear ratio: The sprocket on the engine and the one on the rear axle should have a ratio close to 1:6. 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). A torque converter has a variable speed system between the driver and the driven pulleys so it can improve upon this ratio, which gives the torque converter an advantage over a straight clutch system. It improves the ratio by approximately 3:1 and can turn larger tires and drive at slower speeds without doing any damage to the clutch system. A torque converter is a more expensive system initially but it will last longer and is more trouble free when maintained. Restrictions: Don't try and reduce a go kart speed by limiting the travel of the gas pedal or by putting a restrictor in the carburetor to limit full rpm. Either of these methods will result in the clutch slipping, which is self destructive. A clutch needs full rpm to lock up as quickly as possible to be able to start to cool down. To slow down a go kart you would need to purchase a gear reduction unit, which is like training wheels on a go kart until the driver gets use to how the go kart handles. A gear reduction unit can reduce the speed of the go kart in half. Keep the clutch and chain lubed. Oiling a stiff, dried out chain is a waste of time. If your kart has a grease fitting in the crankshaft for lubrication then a shot of grease once a month should be sufficient lubrication. The grease is coming from the inside of the sprocket outward, which is a better way to lubricate the clutch.

The keyway in the crankshaft acts as a reservoir for the grease, which cuts down on the frequency needed for maintenance compared to oiling the snap ring area. The chain still needs to be oiled frequently to keep it from kinking up. There are some excellent chain sprays available that are waxy and will not let sand and dirt adhere to them. Dirt and sand will wear the chain as well as the sprockets. All chains stretch over time. When the chain starts falling off the sprocket then it is time to move the engine forward or backward to take up the slack in the stretched chain. There are four bolts that hold the engine on the motor mount plate. Tighten the bolts back again but make sure the two sprockets are perfectly aligned with each other. You don't want the sprockets out of alignment because this will cause the chain to come off or wear the sprockets unevenly. Leave about half an inch of play between the top of the chain and the bottom, don't pull the engine back where the chain is a tight as you can get it. A tight chain can cause the kart to move in neutral with no one in the drivers seat. A tight chain puts friction on the bushing or roller bearing, which could cause it to engage when the engine is idling. A tight chain also wears out the sprocket teeth really fast. Teach your child how to do the maintenance on the kart and accept responsibility for its upkeep. Every second tank of gas in the kart is about the interval for oiling the chain and the bushing. Clutch warranty: How long will the clutch last. But, if it's improperly installed, driven in abusive conditions (sand, steep terrain, excessive weight in the kart or rear tires taller than 15 inches), the clutch might only last 20 minutes. If the shoes are blued don't bother sending the clutch back for a warranty replacement. Heat damage is not a factory defect, it wasn't sold with blued shoes. If the clutch is abused, the tell tale signs are easy to spot.
