Me and a mate have been trying to bleed my clutch on my 80 series for 5 hrs and carnt get anywhere. What the hell am I doing wrong? I can do everythingt else other then 1 of the simplist job

    Obviously, I can't see what you are doing but here's a tip.... Put a clear plastic hose (usually fish tank air hose works...if it's a bit small, you can warm it up in hot water to soften it up) on the bleed nipple and put the free end into a jar that has some brake fluid in it. Open the bleed valve and gently work the pedal 'till no more air comes out of the hose. Keep the plastic hose submerged in the fluid while doing that and don't take it out 'till you have the valve closed. If it still does not work, then you have a problem either with the master internally bypassing or the slave or line has an air leak. Or, the clutch itself isn't working.

Just follow the procedure in the right order. Fill the clutch reservoir on the master cylinder to the max and leave the lid loose. Fit a transparent plastic pipe on the bleed nipple on the clutch slave cylinder bleed nipple. Put the other end of the pipe into a jar to catch the waste fluid. Put some thick grease around the base threads of the bleed nipple, this stops air being sucked in via the threads whne the nipple is slackened off. Loosen the bleed nipple by 1/3 of a turn. Have your mate slowly depress the clutch peddle. When he has reached maximum travel have him hold it there while you turn the bleed nipple a third turn back to tight. Have your mate release the clutch peddle, clutch fluid from the master reservoir should now fill the the master cylinder. Have you mate press the peddle a quarter way and then release the bleed nipple a 1/3 of a turn. Have your mate depress the clutch peddle all the way to maximum travel. Again tighten off the bleed nipple before releasing the clutch peddle. Keep doing this process until no more air bubbles can be seen in the fluid in the pipe attached to the bled nipple. Every four cycles or so check on the fluid level in the master reservoir and keep topped up with fresh fluid. When everything completed tighten the bleed nipple, it is not necessary to tighten the hell out of it as at some point you may need to do this again. Wipe everything down pump the clutch peddle a few times to be sure of correct operation and no leaks.

    Thanks for the reply joe, but im sorry to say weve done it exactly as you have said it, everytime I crank the slave cyclinder bleed nipple nothing comes out, its like there is no fluid in the line, but there is heaps and no leaks. This 1 has got me baffled.

  • Joseph Prosser Jul 01, 2011

    Maybe there is a blockage in the bleed nipple or the bleed hole within the slave cylinder. Just remove the nipple altogether and apply the clutch. If the fluid pees out then at least you were going to lose some of it any way, if not then it is likely that the slave cylinder bleed hole is blocked twisting a small drill bit by hand often does the trick.

bleeding a clutch is a 2 person or pressure bleed job
have a mate pump the clutch pedal the hold it down while you open the bleeder nipple
close the nipple and repeat the pump action
hold down and open the bleed nipple
repeat the operation until you have a solid pedal and no air coming out
keep an eye on the fluid level in the reservoir

I have replaced the clutch,pp. and throwout in my 1985 f-250 and it doesnt disengage.i have since replaced both clutch cylinders to no avail.HELP!!!!

I have a 1985 F-150 and replaced all of the same as you. You have to bleeed and bleed and bleed the clutch master and slave cylinder. I thought there was something wrong but apparently if there is just the slightest amount of air anywhere in the system the clutch will not disengage. Also from the tiny air bubblees generated from the bleeding proccess you need to take a break and allow some time for the air to settle and rise between bleeds. Have patience it will work.

Please save me from CLUTCH HELL

Have your mechanic ck for a possible issue with the pilot bearing. if the clutch linkage is indeed full travel, then the clutch should be "disengaged" and the only thing left is a pilot bearing (which should be replaced at every clutch replacement) or there is a problem with the disc. If clutches dont last 100k miles it either the driver or cheap parts.

Master or slave cylinder...leakage?? lines..??

I am totally unfamiliar with the particular setup you have, however I know a bit about clutches, Sifting through what you said, it appears that your clutch is set up too tight. By this I mean that the throwout bearing is always pressing on the release diaphram (or fingers) on the clutch cover. As you drive this is causing the clutch disc to overheat and slip. The repeated bleeding you are doing likely has no effect on this other than that the time you spend bleeding is allowing the clutch assembly to cool off. If the slave cylinder is part of the throwout bearing and is inside the bellhousing you need to remove it and get one that is slightly shorter. If the slave is mounted on the bellhousing and activates a clutch fork that moves the bearing you will need to find a means of backing off the slave adjustment so there is a bit of freeplay between it and the fork. likely since you can drive it you are looking at 1/4" or less play to get it right. My only concern would be that you may have overcentered the fingers on the pressure plate and damaged the return spring. slipping the clutch also has not done good things to the disc either. (like driving down the road with your foot on the brake is not good for brake pads)
Good luck with your project !!

How do you bleed the clutch in a 1991 Jeep Wrangler?

If replacing just the fluid, you should gravity bleed it by opening the valve at the side of the transmission where the line goes in to connect with the slave cylinder. Be sure to stand by and keep the tiny reservoir from going empty during bleeding, or you just make things worse. Assume you replaced parts. Is this right or wrong?

Or are you just trying to restore performance in a poorly operating system? Would help TONS to know these details, and how much you know about bleeding, etc. If you are trying to bleed a new slave cylinder, it can take 600 to 1800 pumps of the clutch pedal sometimes to clear it out manually. If you want instructions on how to bleed in with vacuum assistance, please post request comment to that effect.

Talk to you soon. TT

Clutch not responding

well if you have mixed a wrong type of fluid (such as power steering or oils) you are going to have to replace the clutch master cylinder and slave cylinder. Before you install the new parts be sure to drain all the old fluid out of the clutch line, and flush the clutch line with brake cleaner and blow compressed air thru until its clean and dry. install your new parts and fill with fresh (NEW) fluid whatever the manufacturer recommends most any DOT 3 or DOT 4 brake fluids will work (read the cap on the resivoir) and proceed with bleeding the air from the system, i usually fill up the resivoir with the bleed screw open(on the slave) until fluid with no air comes out and then proceed with the bleeding process this is called gravity bleeding and will help speed things along be sure to rate this and good luck this is not very hard to do and should take about an hour HERE IS THE MASTER
AND HERE IS THE SLAVE about $80 in parts altogether including fluid please rate _JEFF
