1. Fill up the clutch reservior with right type and DOT of fluid (Dot 3 or Dot 4)
2. Have someone help pump the clutch paddle.
3. have the helper pump the paddle 5-7 time and hold it down and you open the bleeder and close it before the helper lets off the clutch paddle.
4. Keep repeating the above procedure until you see clear fluid coming out and no air is coming out with the fluid.

Good luck.

Clutch pedal goes to floor. I change the clutch, pressure plate and throw out bearing. Still no clutch pedal. Changed out the cylinder that presses against throw out lever arm and bled it. Still no clutch...

you need to pressure bleed the system, or you can fill the brake system to over fill as it needs to be over the pipe for the clutch line. and keep it there and pump and bleed the line, but before pumping undo the bleed screw and put bowl uner to catch fluwid and fill the line up till it runs out clear with no bubbles. then tighten the bleed screw. then fill up and pump pedal, the re bleed. should be done then, pressure kit doe this all in one just hold clutch down and undo the bleed screw let air out etc then tighten up. and its done. used for doing the breaks as well.

Why does clutch leak off and wont go into gear 96 toyota tacoma when you push on clutch pedal goes to the floor it wont engage clutch to be able to put into gear

the most likely reason is either the clutch master cyl. needs to be replaced.or the.slave cyl. its mounted down on the transmation under the hood find the resivore for the clutch. check the fluid level.if its low , fill it back up , and look for signs of a leak
you will probally have to bleed out all of the air from the system.its done almost the same way as bleeding the brakes. Good Luck.

I press on the clutch and it seems that I have no clutch. I installed a new presure plate and when I was done I went to turn on the truck the clutch pedal does not seem to work the clutch

I don't know if you have hydraulic clutch cylinder but sounds like it may be bypassing or have air in system. Try bleeding system and checking for pressure when pedal is pushed

How do i go about bleeding the clutch on a1994 chevrolet 3500.

Its bascily the same princable as bleeding brakes However you need to look for leaks in differant stops . With the clutch you the resivior that you fill with fluid then the master cylinder witch is attached to the brake pedal with a rod to push it in when you apply the brakes and then the slave cylinder that is located near the clutch disc and pressure plate and flywheel on the bell houseing . The slave cylinder it where the bleeder is located and has a fitting much like a calipar or wheel cylinder that needs to be opened and closed during the bleeding process to let the air out open pedal depressed and closed when the pedal is released so the air can't get back in the system . Air is compresable fluid is not . Look for fluid leaks inside the cab of the vehicle near the master cylinder because if fluid can get out then air is getting in the system and you will never be able to bleed it completly You will need a clear peice of plastic tubeing that fits over the bleeder put the other end in a bottle with some fluid in it already have some one push down on the clutch pedal while you have a wrench on the bleeder to open and close it as required when the air bubbles stop comeing out the end of the tubeing that is in the bottle with the fluid you are done bleeding the system Good luck its not that hard you just need two people to do it and make sure the bleeder is closed when the pedal is travaling up or you will **** air back into the system

My clutch went out and i had a mechanic friend replace the part...its the part under the engine not the actual clutch but he cant get pressure back in the clutch and cant figure out if bleeding the system...

Bleeding the system is as follows. It also helps if you have a length of clear plastic tubing that fits snugly over the tip of the bleed nipple, which makes it easier to see if there are any air bubbles still coming out.

1. Start with the Master Cylinder full of fluid. (Don't forget to check after a few bleeds that it stays above ¼ full so that you don't introduce more air into the line).

2. Have an assistant pump the clutch pedal 2 or 3 times, then hold down, keeping weight on the pedal as fluid is released.

3. Loosen bleed nipple to release any air & fluid.

4. Tighten nipple. Assistant then lets clutch pedal return. It may be necessary to manually pull back pedal if it does not return by itself.

5. Wait a few seconds then repeat the sequence from #2.
Bleeding is complete when no more air bubbles are visible in the fluid released from the bleed nipple. If clutch is still spongy you may have to repeat the bleeding after a few days driving.

Ran out of clutch fluid now there is air in line...clutch is all the way to floor...how do i get air out of line...have tried everything

It's a matter of bleeding the clutch system completely. You do need to make sure you don't ,have any leaks at the Clutch Master Cyl. or at the Clutch Slave Cyl or the line running between both, and that you don't have clutch fluid in the drivers compartment just below where the clutch rod comes through the firewall. That would of course mean you have to replace the Clutch Master Cylinder due to internal leakage.

This isn't so unusual, you'll have to pull up on the pedal by hand & pump it a few times to get pressure enough to properly bleed the system, or, you will have to start with bleeding the Clutch Master Cyl. first by loosening the line there & have someone push down the pedal, then before letting up on the pedal, tighten the line to prevent air from being drawn in. Repeat two times to get any air out here.

If your parts and lines are all in good shape then re-fill the resivoir & have someone to pull up on the clutch by hand if needed & then if necessary, use their hand to depress & pull the pedal a few times to try & build some pressure so that you can bleed the Clutch slave cylinder a few times to get all of the air out. After you've finished bleeding the system, the pedal should stay in the up position except when being depressed and you should have consistently even pressure when using the clutch.

good luck.

Bleed cluch 96 ford ranger

Ok you want to check if your slave cylinder is bled and that is the pressure plate. However, the clutch may have pressure, it dose not always engage the clutch all the way witch would cause a slamming of the clutch. Anothing thing is to check is that if you have had your clutch changed recently make sure that the proper clutch has been in staled because there are a couple diffrent choises out their. If thats not it all I can think of is your slave cylinder fluid is low. You can use a hand held brake vaccum bleeder to do this as well and it removes a bunch of the air.

Bleeding a clutch properly removes all the air from the clutch line. You want to remove the air through the master cylinder at the top of the clutch system rather than through the bottom by pumping the clutch pedal. Pumping the clutch will not remove all the air. Bleeding the clutch on a Ford Ranger will take about 20 or 30 minutes.

Raise your truck 6 inches off the ground with a jack. You can drive the truck on ramps if you have them. Lifting the truck will make it easier to bleed the clutch I promise.

Use a turkey baster to **** the brake fluid out of the brake fluid reservoir located at the top of the master cylinder.

Fill the pump style oil can with brake fluid and attach the flex line to the opening on the oil can. Use a new can. You do not want to pump dirt particles or another fluid into the clutch line. This is just good practice I think.

Pump the flex line with brake fluid to remove all the air. You do not want to add additional air to the clutch system.

Open the bleeder valve located on the internal cylinder with a 7mm wrench and quickly attach the flex line to the valve. I believe this is the wrench you need this is what the size of my ranger is but yours may differ. (Remember the slave cylinder may be inside the transmission bell housing.)

Pump the can to move brake fluid up the clutch line. Stop when you no longer see bubbles coming out of the brake fluid reservoir. It should take about 5 minutes to remove all the air from your system.

Use the wrench to close the bleeder valve and remove the flex line from the bleeder valve and this should complete your job.

I hope you have the best of luck with this project!
