If you have had the flywheel cut, have a clutch with a different release height (different finger or diaphram design & height) or a remanufactured pressure plate, or all of the above, you may run into this problem.
Small differences there translate to a large difference at the pedal. On linkage type designs, there were several options including longer/shorter throwout bearing or adjustable fork pivot ball. Hydraulic systems should compensate somewhat, but if you are beyond the travel of the slave cyl, I'm not sure there is anything you can do from the outside. I would check that there are no air leaks. If you have an external slave cylinder you may be able to make a slightly longer rod that connects the slave to the clutch fork. I really can't think of anything else to do at this point.
Hope this helps a bit.

New clutch not disengaging


When I do clutch jobs. I replace the clutch package(comes with the slave) and the master cylinder also. Have the flywheel turned or replaced. Just a note. The clutch plate can be installed backwards. No matter how many times you bleed it, It won't work.

2000 jeep wrangler clutch has to pressure and thus wont allow me to put it in gear.


Check the clutch fluid level. If it's low, add some (takes brake fluid). There is a bleed valve down on the clutch slave cylinder on the bellhousing. Open the bleed valve and have someone push the clutch pedal slowly to floor, and hold. Close the bleed valve, and repeat until fluid comes out in a steady stream when the pedal is depressed. Your pedal should have pressure now, and the clutch should be working.
If no fluid is forced out the clutch master cylinder, into the line, and to the slave cylinder when clutch is pressed, then you may have a bad clutch master cylinder. If fluid does come out the bleed valve, but still no pressure on the pedal, it may be a bad slave cylinder.
Post back for more. Would like to know what you find out, and what the problem was, OB. Good luck.

I recommend bleeding the clutch using instructions pasted from autozone.com below. As for the engine light, please get the computer scanned and send us the diagnostic trouble code.
Hydraulic System Bleeding NOTE
It is necessary to bleed the clutch hydraulic release system if the system has lost an excessive amount of fluid and has allowed air into the circuit. Air in the system typically results in a spongy pedal feel, and/or improper clutch release. If air cannot be removed from the system using this procedure, it is necessary to replace both the clutch master cylinder and slave cylinder assemblies.

Except Turbocharged Models
  1. From driver's seat, actuate clutch pedal 60-100 times. Verify clutch operation/pedal feel. If pedal still feels spongy, or clutch does not fully disengage, excessive air is still trapped within the system. Perform the following procedure:
  2. Verify fluid level in clutch master cylinder reservoir. Top off with DOT 3 brake fluid as necessary.
  3. Raise and safely support the vehicle.
  4. Remove clutch slave cylinder assembly from the transaxle case, but do not disconnect from the system. Allow the slave cylinder hang, making it the lowest part of the system.
    CAUTION
    While slave cylinder is detached from the transaxle, DO NOT actuate the clutch master cylinder. Damage to the slave cylinder will result.
  5. Depress slave cylinder pushrod until it bottoms and then release. Repeat this at least ten times, forcing trapped air upwards and out of the system.
  6. Re-install slave cylinder into position. Torque slave cylinder to case bolt to 168 inch lbs. (19 Nm).
  7. Carefully lower the vehicle.
  8. Check and adjust clutch master cylinder fluid level. Actuate clutch pedal thirty (30) times. Verify clutch operation/pedal feel. If pedal still feels spongy, or clutch does not fully disengage, air is still trapped within the system. Repeat Step 3 through Step 7 until air is purged. If several attempts at purging air from the system are unsuccessful, replace both the clutch master cylinder and slave cylinder assemblies.
  9. Raise and safely support the vehicle.
  10. Carefully lower the vehicle.
  11. Top off clutch master cylinder fluid level with DOT 3 brake fluid as necessary.
Turbocharged Models

NOTE
Due to the angle and design of the turbo hydraulic system components, gravity and pedal bleeding are less effective and less efficient than the reverse fluid injection method (reverse bleeding). Reverse bleeding is recommended for this system, and requires the use of commercially available injection bleeding equipment.

Alternate Procedure (Pedal Bleeding)
  1. Remove reservoir cap and inspect fluid level. Top off with DOT 3 Brake Fluid. Actuate clutch pedal briskly at least 50 times. Verify release system function. Repeat. If release system is still inoperative, continue with procedure.
  2. Raise and safely support the vehicle.
  3. Remove clutch bellhousing access cap to expose system bleed screw.
    WARNING
    Use care not to allow fluid to drain into clutch bellhousing. Excessive fluid will be agitated and sprayed around inside the clutch bellhousing by the rotating flywheel, contaminating the flywheel, disc, and pressure plate, resulting in poor clutch engagement.
  4. Using suitable socket/wrench, loosen bleed screw. Immediately install rubber hose to bleed screw to prevent fluid from entering clutch bellhousing. Tighten bleed screw gently with suitable wrench.
  5. Lower vehicle.
  6. Have helper actuate clutch pedal to floor.
  7. Place collection container at end of hose to capture expelled fluid.
  8. Using suitable wrench, break bleeder screw loose and tighten to 62 inch lbs. (7 Nm). Do not over-tighten.
  9. Have helper release pedal, returning it to at-rest position, and then actuate pedal to floor.
  10. Break bleeder screw loose and tighten to 62 inch lbs. (7 Nm). Do not over-tighten.
  11. Repeat procedure as necessary, keeping master cylinder reservoir full during the process, until air bubbles are no longer visible in collection container.
  12. When air bubbles are no longer visible, actuate clutch pedal briskly at least 50 times.
  13. Verify release system function and top off fluid as necessary.
Recommended Procedure (Reverse Bleeding)
  1. Remove reservoir cap and inspect fluid level. Top off with DOT 3 Brake Fluid. Actuate clutch pedal briskly at least 50 times. Verify release system function. Repeat. If release system is still inoperative, continue with procedure.
  2. Remove reservoir from bracket and empty into collection container.
  3. Raise and safely support the vehicle.
  4. Remove clutch bellhousing access cap to expose system bleed screw.
    CAUTION
    Use care not to allow fluid to drain into clutch bellhousing. Excessive fluid will be agitated and sprayed around inside the clutch bellhousing by the rotating flywheel, contaminating the flywheel, disc, and pressure plate, resulting in poor clutch engagement.
  5. Using suitable socket/wrench, loosen bleed screw.


    Fig. Location of the bleed screw for the 2.4L engine
  6. Quickly attach hand operated bleed apparatus to bleed screw. Use care not to over-fill reservoir and spill fluid into engine compartment.
  7. Operate bleed gun sufficiently to expel air upward through circuit and out of master cylinder reservoir. Fill and empty reservoir three times.
  8. Remove bleed apparatus and tighten bleed screw to 62 inch lbs. (7 Nm). Do not over-tighten.
  9. Carefully lower the vehicle.
  10. Top off reservoir with fluid, then return the cap.
  11. Verify system operation. Actuate clutch pedal 50 times. If necessary, repeat procedure until road test confirms that shift issues no longer exist.

Where is the slave cylinder


the slave cylinder looks almost like a small brake master cylinder usually near the rear of the engine compartment and will have a fill line just the same. It is used in the hydraulic operation of engaging/disengaging the clutch from the pressure plate

You have to bleed it at the slave cylinder not the master cylinder.Keep the bottle on the m/cyl full at all times and do not disconnect any lines.Bleed the system at the sl/cyl.Then do it again after a short drive.You still have air in the system.If you take off any m/cyl lines,you have to start all over again.
Hope this helps

Where is the bleed valve for clutch on a 1991 jeep wrangler


1. Fill master cylinder reservoir with DOT 3 brake fluid. Raise and support vehicle. Attach bleeder hose to bleeder screw on bleed line of slave cylinder. See Fig. 1 (attached in link) . Place other end of hose in glass container 1/2 full of brake fluid. Loosen bleeder screw while holding bleeder screw fitting.

2. Have an assistant depress clutch pedal to the floor. Tighten bleeder screw and release clutch pedal. Repeat bleeding procedure until fluid entering container is free of bubbles. DO NOT allow reservoir to run out of fluid during bleeding. Refill clutch master cylinder reservoir.

CAUTION: DO NOT allow bleed line to bend or flex when loosening
bleeder screw.

Clutch pedal stays 2 the floor on a hydralic clutch system on a 2000 camaro v8. clutch master cylinder is new also slave cylinder and clutch and pressure plate


Did you bleed the system? When you replace the the master and/or slave cylinder you have to bleed the system just as you would with brakes. There is a bleed screw on the slave cylinder. Open the bleed screw, have a helper depress and hold the clutch pedal down.Tighten the bleed screw, then release clutch. Repeat this procedure until you have removed all air from the system and the clutch pedal is firm. Keep an eye on the fluid level to avoid sucking air into the system. If you have done this, remember there is a possibility that the master or slave cylinder is defective.

New clutch won't work.


There are several things to check here. First check that the master cylinder to the clutch is working correctly. Then check that the slave cylinder is working. The Fords are sometimes difficult to bleed. The other item unfortunately is in the bell housing. There is a pivot that the release fork rolls over in the bell housing. Fords are famous for these breaking and causing the clutch to not disengage. The other problem could be the release fork is bent. These are not all fix it items. Just all the probable items that could be the problem. Hope this helps you. Usually you can just get the flywheel resurfaced for about $12. Was your flywheel junk? I hope someone didn't just decide to sell you a flywheel. Let me know what you find.

1990 jeep wranger slave cyclinder


The clutch slave cylinder on this model is located inside the transmission bell housing. You would have to pull the tranny to see it.
Bleeding the slave cylinder is a fairly simple process.
Underneath the vehicle on the driver side you will see two hydraulic lines going into the transmission where the tranny connects to the engine. If you have trouble locating just follow the hydraulic line from the master cylinder on the firewall.
One of these lines is actually sticking out of the tranny and has a bleeder valve on the end.
You will need a 9/16 box end wrench and a 5/16 or 1/4 inch box end wrench and someone with you to press the clutch pedal while you are under the vehicle.

1. Top off the master cylinder with clean brake fluid. Also, MAKE SURE you keep the fluid level in the master cylinder topped off during this process. You may need to have a second helper to take care of this so you don't have to keep climbing out from underneath.

2.Hold the line with the 9/16 and loosen the bleeder valve a couple turns or until fluid begins to drain. Have someone SLOWLY depress the clutch pedal to the floor and hold it down to the floor until you tighten the bleeder valve back up. MAKE SURE YOU ARE OUT OF THE WAY OF THE SQUIRTING FLUID WHEN THE PEDAL IS DEPRESSED!!

3. Once you are sure the valve is tight, have them pump the clutch pedal a couple times . Repeat step two until the pedal has a full stroke.

my rodeo had the same problem i corrected it by bleeding the slave cylinder. and is located on the driver side on the gearbox you will find it if you follow the line from the master cylinder down to the gearbox and if that helps but happens again it might have to be replaced.
