clutch problems

I put a new clutch master cylinder in. Everything is together properly. I went by the hanes manual to bleed the clutch and it still won't go in gear. I repeated the bleeding process multiple times. Any ideas what to do next?
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
Hi there. The first thing I’d do is double check the clutch pedal and linkage to ensure it’s properly aligned and adjusted. Sometimes when installing a new master cylinder or internal clutch component, the linkage or release point of the clutch will change. If that’s good, it’s likely that you might need a professional mechanic to adjust your clutch for you; as this process can be very tricky (especially on early 90’s Ford pick-ups).

Common reasons for this to happen:

Broken Clutch Cable: The most common reason to have a clutch pedal that goes all the way to the floor is a broken clutch cable. This is extremely common, particularly on older cars. Replacing the cable will allow you to engage the clutch and change gears once more.

A clutch pedal that won`t return is either sticking (due to friction) has a broken or weak return spring or is throwing out beyond the point it should (like an athlete hyper-extending their knee).
Similar to brake pads, clutches do not have a recommended replacement mileage. They do wear out, but some will last over 100,000 miles.
A clutch that won`t engage at all means there is serious damage somewhere. Check for a bent linkage, a seized slave cylinder, or a seized throw-out bearing. Beyond those, check for binding in the linkage, a corroded cable, or a failed friction plate.
There could be a leak on the slave cylinder causing the slave cylinder not to operate. Also, check the pin to the clutch pedal and make sure that it is hooked up to the clutch master cylinder. Check the lines and make sure that they are not cross threaded, which will not seal and cause a leak.
Sudden failure is most often caused by a broken or loose clutch cable, linkable or a failed hydraulic master/slave cylinder. There can also be leaks in the hydraulic line or even the disc could be contaminated with something like dirt or debris.
The time it takes to replace a clutch can vary depending on the type of vehicle you have, but it`s generally between two and six hours. For many, this means you could take your car into the garage in the morning and get it back the very same day!
Most clutches are designed to last approximately 60,000 miles before they need to be replaced. Some may need replacing at 30,000 and some others can keep going well over 100,000 miles, but this is fairly uncommon.
For some vehicles, sticking may mean a clutch cable repair or adjustment. Hydraulic issues may mean replacing seals and gaskets or perhaps replacing the master and/or slave cylinders. Other common repairs include resurfacing or replacing the flywheel.
Generally, clutch pedals are connected to the clutch release lever by either a cable, or by a hydraulic system using a master and slave cylinder connected by a pipe. If the clutch engages suddenly just off the floor it is because the cable needs adjusting or the hydraulic system has a leak

problem with clutch or transmission or both
ANSWER : It does not sound like you are having an internal transmission failure. It sounds like you have a clutch issue. Most of the time when this occurs the clutch plate either breaks or the pressure plate loses one of its springs. Both will cause this to occur. It can even be binding in the throw out bearing in the clutch. The transmission would need to be removed from the vehicle in order to properly diagnose this. You should have a transmission specialist check it out.

Why does my clutch pedal sink to the floor and dosent come back up?
ANSWER : Hi – there are 2 main causes for the clutch going all the way to the floor. First – check that the return spring on the clutch pedal is in place. Second – I see you bled the system – bleed the system again. This is how I would do it – use a short length of hose connected to the bleeder screw, run that hose into a cup half full with recommended fluid…fill the reservoir, then have one person pump the pedal while the other opens the bleeder screw and watches until NO BUBBLES come out (and makes sure the reservoir doesn’t run dry). Then close the screw fill the reservoir to the mark, and test her out. If you would consider, YourMechanic can send a certified technician to you and assist you in troubleshooting this clutch issue.

My clutch is not working Entire clutch repair or clutch master cylinder repair? How do I check the cylinder?
ANSWER : Hi there. Check the slave cylinder to the clutch and see if the piston is all the way out. If the piston is all the way out or its not touching the clutch fork, then the release bearing has broken and the fork has moved into the clutch. If the slave cylinder is relaxed and the fork is against it, then the clutch pressure plate has sprung a pressure spring. If the pedal can go down but not all the way to the floor, then the clutch needs replaced with a new release bearing. If you need further assistance with a clutch replacement, then seek out a professional, such as one from Your Mechanic, to help you.

Clutch pedal stays to floor. Replaced master cylinder. Clutch push rod broke. Also do I need to change slave cylinder
ANSWER : If you have an issue with your clutch pedal going to the floor, the slave cylinder is normally the cause of this circumstance.

Also, if the push rod has been broken the first step would be to track down a new one because that push rod is a very necessary part of the clutch pedal system.

Once a new push rod has been located and installed, I would recommend having a new slave cylinder installed as well.

If you are in doubt about this repair, I would recommend having it performed by a qualified professional, such as one from YourMechanic. One of our mobile technicians will be able to come to your home to diagnose the issue with your clutch pedal and replace your clutch slave cylinder as necessary.

My car has clutch problem. Starting stops after mild lifting of the clutch. Also not working when I press the accelerator
ANSWER : Hello. If I understand your description correctly, the car stops moving forward after releasing the clutch mid-way, and pressing the accelerator after that point does not accelerate the car. If this is correct, your clutch is most likely worn out or damaged. If this behavior started slowly, it is just worn out. If suddenly the clutch is damaged. In either case, it will likely need to be replaced. I recommend having an inspection of the slipping clutch completed by a professional mechanic, such as one from YourMechanic, so that you can move forward with the proper repair.

I can’t go into 4th or 5th gear and clutch does not engage after a recent clutch job, clutch release while in gear does nothing.
ANSWER : I would rule out the axle not being pushed all the way in. That would effect all speeds and gears. That you can engage gears other than 4th and 5th leads me to 2 m possibilities:
1. Shift linkage mis-adjusted.
2. Possible bent shifter fork internally.

If it feels like you can engage 4th and 5th with the engine OFF, then I would lean towards a clutch release issue.

When replacing my fan clutch should I change my cooling fan to a flex-a-light and get a new flex-a-light clutch?
ANSWER : Hi there. It is best to always put on the OEM parts that are required for the vehicle. However, you can get a flex-a-light clutch fan for your vehicle as long as it will bolt up to your water pump pulley and clear the radiator and shroud. I recommend having a clutch design fan for your vehicle and not a fan that spins with the engine all the time. Those fans will cause the engine to overheat on highways and in town especially in hot weather. If you need further assistance with your cooling fan, then seek out a professional, such as one from Your Mechanic, to help you.
