Question about JEEP Wrangler Unlimited Toy Vehicle
I replaced the clutch, throwout bearing/slave cylinder, and master cylinder in my '87 Wrangler, and now it won't go into gear. I was sure to bleed the system properly (several times, using several methods), and I have good pedal pressure, but still no release.
Is it possible that the retaining ******** the throwout bearing didn't break? The new master cylinder isn't the same brand as the old one (the old one is a Girling, this new one is from CarQuest), but all dimensions and capacities appear to be the same. I don't know what to do, and Jeepin' season is almost over! Please help!

This is not a bleeder hole, this is a weep hole like in a water pump to see when there is seepage past the seals.
Bench bleed the system. With the master cyl. line and slave cyl assembled, place the master cylinder in a vise, fill the master cyllinder. actuate the slave cylinder back and forth lower than the master cyl. This will allow the air to escape upwards back into and out of the master cyl.
Once bled the system can be installed.

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.

Some companies stopped putting the bleeder screws into the slave cylinders. The boss is still there and is threaded but there is no hole in the bottom. You can put a hole in if you wish but they did away with that type because people were having problems bleeding the system. To bleed this style of slave cylinder: 1.Remove the plug from the end of the cylinder where the line goes in. 2. Remove the straps holding the cylinder in. 3. Hold at a 45 degree angle. 3. Pour fluid into the cylinder with the cylinder extended. 4.Slighltly work the cylinder in and out to work any exess air out. Still holding at a 45 angle. 5.Make sure master cylinder has fluid in it. 6. Insert rubber seal and line into slave cylinder while still holding at a 45. 7. Insert roll pin into slave just over half way. This way if you have to remove it you can still get it back out. It probably will not come out if you put it in all the way because they were designed not to come out. You can snip off the straps that hold the piston back. 8. Push the piston back into the slave. This will force any air out that is in the cylinder. 9. Bold slave back on. 10. Pump clutch until it feels right. Make sure there is enough fluid in the resevoir otherwise you will force air into the line. If it dont feel right repeat this process. When all feels right in the petal finish putting the roll pin into the slave cylinder. Good luck. You may need 10 hands!
