Yj slave cylinder bleeding

I have a 95, my slave was leaking so I got a new one from auto zone. I installed it and realized it didn't come with a bleeder screw and the old one didn't have one ether! I went back to auto zone and they sold me a pack I a few different sized bleed screws. I matched the threads and it easily went in to the bleeder port. But all it did was de-thread the slave cylinder! Any way to bleed without the screw without damaging the cylinder?

Yes it had an allen screw installed??? If so gravity feed until it runs fluid. And now don't laugh this is legit. Unbolt slave from bell housing and with cap off master full, point the slave piston at the floor and actuate slowly 20 times. Let it hang go up check master service as required and repeat the process. Reinstall slave se4rvice master as required. It works it was in the instructions with mine.

It worked for me.

And I figured it out without instructions because my slave didnt come with any directions.

Yea the new slave didn't come with a screw or instructions unfortunately. And the old one didn't have a screw in it. But thank you for the advise! I'm going to get this done today! I've been jeepless for 3 days and it's driving me crazy lol

When I bought mine it came full of fluid and pre-bled. It took me about an hour to install and has be running flawlessly ever since. I have heard about the gravity method of bleeding from many others, so I guess it works pretty good.

You probably bought the Master/slave assembly those come pre bled if you buy a slave only it comes empty and has no bled screw or a place to put one. I has to install mine and let as much fluid run into it before I connected the line then point the front end downward and pump the rod for the slave cylinder slowly about a dozen tomes (with the cap off) to force the air upward into the master cylinder. If there were a bled screw I would have gravity bled it but it didnt it looks like they were thinking of haveing one but they didnt drill out the boss for the bled screw.
