What to Do When Your Motorcycle Clutch is Frozen

There is nothing worse than firing up your motorcycle, pulling in the clutch lever and finding out as you drop it in gear that the clutch is frozen. Even the most experienced …rider can be thrown for a loop when this happens. This problem can be the result of a rusty cable, dirt and debris in the housing, or simply poor maintenance. The following steps can guide you in troubleshooting and repairing this common problem.If you are working on one of the older motorcycles with a cable operated system, the first thing you need to look at is the cable itself. If the cable does not move freely, it can give the impression of a frozen clutch. To verify the cables operation, pull on the handlebar lever and observe the release lever on top of the crankcase housing. If it does not move through the full range, disconnect the cable and test it for movement. Lube a sticking cable using a spray can of cable lube you can pick up at any motorcycle and many parts stores for autos.Using the right size Allen wrench, remove the outer clutch cover, being careful not to damage the gasket, or plan to have a new one on hand. With the cable fully lubed and reinstalled, operate the handlebar lever. If the release lever does not move freely, use a can of spray cleaner to clean the entire mechanism. Grease the cam and the pivot points. Work the lever through its full range of motion several times to ensure it moves freely.Take a good look at the release rod. This is located in the middle of the clutch unit where it attaches to the engine. You should be looking for debris or dirt which might be hampering its operation. Remove the rod and the stainless steel ball behind it (not all bikes have this ball). Clean them thoroughly and examine them for signs of damage. Coat both parts with a liberal amount of grease. Return them to their place in the bike.Replace the cover on the bike and install all of the bolts. Drop the bike into first gear. Pull in the clutch lever and attempt to roll the bike forward. The bike should roll forward without any resistance. If it does not, there is an internal problem. It might be in the plates or the springs.Remove the cover again and using the appropriate socket (most are either 8 or 10mm, remove the bolts holding the inner cover and springs. Remove the spring and plates, keeping the stack intact. Examine all of the springs using a set of vernier calipers, your maintenance manual will give you specifications. If any fail to meet these measurements, replace them.Then, examine each disc one at a time. Look for burrs, excessive wear, burn marks or any other type of damage. If you see any at all, replace the entire set. You need to measure the fiber plates, if they fail to meet the minimum specifications, replace them.While you have the plates out is a good time to examine the basket they sit in. Look for nicks, burrs, and groves. The groves are the result of the discs moving side to side during normal operation. When they become too deep, they stop your clutch from working. If you see any signs of damage, replace the basket.Before you can install the new plates, the fiber discs must be soaked in oil. Use the same oil you put in the crankcase. They need to soak for at least an hour. Stack them in the exact same order as they were removed from the bike. This is vital as most motorcycles have fiber discs of different thicknesses in different locations. Each pair of fiber plates must be separated by a steel plate.Once you have all of the plates back in the basket, install the springs and cover. Replace the ball and rod, followed by the outer cover. Connect the cable and adjust it as per your motorcycle's specifications.At this point you need to test the motorcycle to ensure the clutch is no longer frozen. To do this, take the bike off its stand and put it in neutral. Start the engine, pull in the clutch lever. Apply the front brake and drop your bike into gear. It should no longer surge or attempt to move. Slowly let the lever out and your bike should now take off properly.Having a motorcycle with a frozen clutch can be a major problem, one that requires you to completely disassemble and inspect every part of the assembly. There is no way you can continue to ride your bike in this condition. As you take the assembly apart, you need to very carefully examine every part. If there are signs of damage or excessive wear, the best thing you can do is replace them. Your maintenance manual will give you all of the specifications you need to measure things like spring height and plate thickness. If you don't have a manual, you can call the nearest dealer and ask them for the measurements.If your bike has been sitting for a long period of time, it is possible the plates may simply be stuck together. You may be able to free them without tearing the entire bike apart. Place your bike in the highest gear. With the help of a friend, try to rock the bike back and forth. If the plates are stuck, this may break them loose. Once they are loose, take your bike for a ride to ensure everything is in working order. (MORE)

Torque Converter Clutch Problems

Discover how a torque converter clutch works and how to diagnose common problems. When this system develops issues it can cause surging, bucking, poor fuel economy and intermi…ttent stalling.One of the downsides of owning an automobile with an automatic transmission is there is no mechanical connection between the engine flywheel and the drive shaft. It does, however provide a fluid coupling through the torque converter. This is not as efficient as a manual transmission when it comes to fuel economy. In the early 1980s, when computer control modules started making their way onto automobiles, car makers found a way to overcome this inefficiency.They installed an electronically controlled clutch that locks the torque converter shell to the flywheel in the same manner that a clutch would direct power from the engine through a manual transmission. When the converter clutch is applied it completes a 1 to 1 ratio with the engine crankshaft. This eliminates the power loss from a fluid coupling.Car manufacturers needed to solve a few problems before they could deploy an automatic clutch locking system. First, they only wanted to lock up the transmission at Highway speeds over 40 mph. Second, when the clutch is engaged, engine power is reduced, so they needed the ability to release the clutch under acceleration or when the automobile slowed down to a stop. On the transmission side most manufacturers use a [torque converter clutch solenoid](http://www.autozone.com/electrical-and-lighting/torque-converter-clutch-solenoid). This electrically operated solenoid simply engages the clutch or releases it. It's the job of a control module to make the decision on when to energize the solenoid and when it should be turned off. Some of the important inputs that the computer uses to make this decision are as follows. They need to know the throttle position, engine load data from the manifold absolute pressure sensor, intake air density and speed [from the mass air flow sensor](http://autorepair.answers.com/troubleshooting/help-with-mass-air-flow-sensor-problems), vehicle speed and input from the brake switch. With these pieces of information they can determine with a high degree of accuracy when the car would benefit from having the torque converter clutch applied and released.Since the torque converter clutch is either engaged or disengaged the symptoms fall into those two categories of malfunction. If the vehicle is slowing down for a stoplight and the clutch fails to disengage, the transmission will stall the engine when it stops. It's the fluid coupling inside the torque converter that allows the engine to idle while the automobile isn't moving.When you remove this by locking it to the engine it acts like a manual transmission at stop signs. The symptoms feel like you were trying to stop at a traffic light without pushing in the clutch pedal on a stick shift car. In other words, you feel a violent surging and bucking as the vehicle slows from 5 mph and it will stall the engine when it reaches 0 mph.If the solenoid fails to lock up the system at Highway speeds the driver will notice a few telltale signs. Normally when an automobile is driving at 55 mph the engine is loping along at around 1500 RPMs. When the clutch fails to engage at this speed the RPMs will be much higher. The other main symptom is poor fuel economy. On some automobiles this can be drastic. If the engine is running at a higher RPM at Highway speeds, gas consumption increases. Drivers can see a reduction of 5 to 10 miles per gallon with this type of torque converter clutch problem.This is where a piece of good news enters the conversation. Although some of the symptoms can make it feel like there's a [horrible problem inside the transmission](http://autorepair.answers.com/troubleshooting/signs-your-automatic-transmission-needs-repair), diagnosis and repair of the issue are often a small fraction of the cost of other transmission problems. As an example, replacement of the torque converter clutch solenoid usually costs under $300. This is when they mount the part on the valve body of the transmission and [removal or overhaul of the transmission](http://autorepair.answers.com/mechanical/why-is-a-transmission-overhaul-so-expensive) is not necessary. Car owners can perform some DIY diagnosis by locating the TCC solenoid electrical connector and disconnect it to see if the symptoms of bucking, surging and stalling at stop signs disappear. (MORE)

Solutions to Hydraulic Clutch Problems

This article will cover common hydraulic clutch problems, discuss how to properly bleed the system and review the common mistakes made during the procedure. Learn about the tw…o major components which are the clutch master and slave cylinders. Review a list of symptoms and best practices when replacing these hydraulic components.Hydraulic assisted clutches have been around for several decades and were designed to bring a new level of comfort while maintaining reliability and performance. The hydraulic system amplifies the strength of the driver's leg while reducing fatigue. Any owner of a manual transmission car will tell you that being stuck in an 8 mile traffic jam can push you in the direction of purchasing an automatic transmission on your next vehicle.Without diving to deep into the theories of hydraulics it's safe to say these modern systems provide an ample amount of application force to fully disengage the clutch from the flywheel while at the same time requiring less leg strength to do so when compared to old-fashioned cable operated systems. Sometimes people forget the only thing accomplished by pushing the clutch pedal to the floor is creating a small space between the clutch disc and flywheel. When this occurs an engine is allowed to run at any RPMs without rotating the input shaft of the manual transmission. This function allows for engine idle, easy shifting and controlled take off from stops.When a component malfunctions the first symptom is failure of the clutch to disengage from the flywheel. Some drivers will complain they can't start the vehicle in gear, can only start it when in neutral, or the car moves as the starter cranks. Another complaint would be a stalling condition when stopping at lights or stop signs. This is because the transmission input shaft is turning all the time.When the input shaft is turning it can also be hard to switch gears and apply reverse, which on many models is an unsynchronized gear. Another common complaint from drivers with hydraulic clutch problems is pedal feel. Although it's easy to push the pedal all the time, experienced drivers can feel the difference between easy and the pedal doing nothing. This can be manifested as a complaint of [spongy or soft clutch pedal](http://www.clarks-garage.com/shop-manual/ts-04.htm). Drivers can also report it goes to the floor with no rebound.Most mechanics agree the first thing to check when problems are suspected is the clutch master cylinder fluid. This component is usually mounted to the engine compartment side of the firewall and will have a small reservoir with a minimum and maximum fluid level. Most of these systems use brake fluid, but this should be confirmed in the owner's manual and is often printed on the reservoir cap.Fluid in the reservoir should be above the minimum line and in good condition. Low liquid amounts could be an indication of a leak, triggering a careful inspection for wetness between the slave and master cylinders. Hydraulic fluid should look clear like the stuff in a new container of the same type. Reservoirs containing cloudy, murky or dark fluid can indicate a few different problems. The fluid may be contaminated. The dark and cloudy consistency could also be a sign of deterioration of the internal rubber seals of both the slave and master cylinders.It's recommended that the clutch master and the slave cylinder be replaced in pairs. There is good reason for this as one of the most common problems is contaminated fluid ruining the primary and secondary rubber seals in both components. Therefore anytime murky or discolored fluid is observed and replacement of either cylinder is required it's also recommended to replace the other. Failure to do so can reduce the reliability of the repairs.Bleeding a hydraulic clutch is different than bleeding brake systems. One big difference is the amount of fluid the hydraulic clutch system holds. Smaller amounts of reserve fluid means careful monitoring is required during the bleeding operation. At any point it runs dry in the reservoir the procedure must be restarted. Another difference, is on a brake system the pedal is pumped until pressure builds up in the lines. Since the hydraulic clutch only has the reservoir, one short line and one cylinder, pumping the clutch pedal is not necessary and can hinder the process. When bleeding clutches it's recommended to start with a good gravity bleed. This is when you fill the hydraulic fluid, open the fitting on the slave cylinder and allow gravity to pull the liquid down through the hydraulic system. After a gravity bleed is yielding a steady output of fluid from the fitting on the slave cylinder one push on the clutch pedal at a time will work any remaining air out. The procedure is as follows. With the slave cylinder bleed fitting closed the pedal is depressed and held against the floor. Then the fitting is opened. After a brief time the fitting is closed and the clutch pedal is then allowed to rise up from the floor pulling in new fluid. The clutch pedal is pushed and held to the floor again and the bleed fitting is reopened. This pushes air out and pulls in new fluid. Since the stroke is short it may take some effort to squeeze all the air out. If forced to do this yourself consider purchasing a [one man bleeder kit](http://www.harborfreight.com/one-man-brake-bleeder-kit-37201.html). At around eight dollars it's a good investment. (MORE)

Learn About a Master Cylinder

Master cylinders are vital components of your car. They are used in both the brake system and the clutch system. If you are having problems with either of these systems, it ma…y be caused by your master cylinder. Learn about the functions of a master cylinder and possible problems you may experience below.A master cylinder converts non-hydraulic pressure into hydraulic pressure. In your car, it provides pressure to the two separate circuits of your brake system. Without it, your brakes would not function. A master cylinder is also used in the clutch system. It's necessary for the car to be able to change gears.A master cylinder works through pistons that create pressure. In the brakes, this pressure pushes the brake pads towards the wheel to create friction and stop the movement of your car. In the clutch, the pressure of the master cylinder causes the clutch to disengage from the flywheel, allowing the car to switch gears. Master cylinders require brake or clutch fluid to function.If you're experiencing problems with your brakes or clutch, it's possible that a master cylinder is to blame. If you push your brake pedal to the floor with little to no results, it may be that you have a broken master cylinder. Try replacing your brake fluid first. If this does not solve the problem, it is probably your master cylinder. It's not usually possible to repair a master cylinder; it will have to be replaced outright. A bad clutch master cylinder may also manifest in pedal problems. If your clutch pedal is hard to push, too easy to push, or stays stuck to the floor when pushed, the problem may be your master cylinder. If shifting becomes difficult or noisy, this may also indicate a master cylinder problem. The only way to know for sure if your car problems are caused by a master cylinder is to take your car to the mechanic.The cost for your master cylinder replacement will vary depending on the make and model of your car. A typical cost for both parts and labor is between $300 and $500. The master cylinder itself can usually be purchased for around $150. Replacing a master cylinder is not an easy job and should not be attempted as a do-it-yourself project unless you are an experienced mechanic. The master cylinder is a vital part of your brakes and clutch and should be installed properly for safety.Master cylinders are necessary for your car to run properly. If you think you may have a problem with a master cylinder, see your mechanic. Failure of a master cylinder can be a safety issue and should be taken seriously. If you're concerned about the cost, get quotes from several different mechanics to make sure you're getting the best deal.Regular visits to the mechanic can prevent master cylinder problems before they occur. Don't neglect your car until it already has a problem. Preventative care can save you money in the long run. (MORE)
