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

1990 chevy silverado wont disingage new clutch and pressureplate...master cylinder and slave cylinders are new and have been bleed extensively...cant figure out why it wont fully disingage


this is really a simple problem to fix. Pull the gear box and turn the clutch pale around because the plate hub centre is hitting on the flywheel stud heads . The clutch plate only go in one way.

My 87 jeep wrangler shifts fine when not running. will not manually shift into gear when running?


sounds like your clutch is not disengaging. when you press on the clutch pedal you should feel the resistance of the clutch pressure plate. There is a pilot bearing in the flywheel when it goes bad it continues to turn the transmission mainshaft not allowing your gears to line up for a shift, but you have noticed a bad noise if this were the cause. Or your clutch hydraulics have gone out. check your fluid level. if low you may have sucked some air into your system. you will have to bleed the lines as you would for car brakes. The other possibilities are bad clutch master cylinder or slave cylinder,

Sounds like a leaking master or slave for the clutch that is not permitting full disengagement. If it only happens when cold it could also be caused by incorrect lube (too heavy) in the transmission, but that is unusual.
Make sure the fluid in the clutch master cylinder is full and that there is no visible seepage where the rod enters from the pedal and that there also is no seepage at the slave unit.

!991 Jeep Wrangler clutch pedal loses pressure. I have to pump it to get enough pressure to shift. I keep it full of brake fluid. I can see no leaks. Thanks for any help.


leaky slave or master cylinder - if you have someone listen to the slave cylinder while you press the pedal is should "squelch" if there is air in there, if the slave cylinder doesn't make a squelching sound then the master cylinder or a hydraulic line between the two cylinders is leaking - slave cylinder isn't very expensive but the master cylinder can be rather pricey. and any good parts shop or motor-factor can source or make-up a new hydraulic line if it is the line itself that is leaking.

1990 wrangler all new slave cylinder, pressure plate,clutch,flywheel,master cylinder,only have 2 inch of pedal,after bleeding.Is there away to bleed system I dont know about.


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.

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.
