How to bleed clutch slave cyl, 94 Wrangler ??
 

My 94 Wrangler ( ~150,000 miles) recently got hard to shift. In
particular, I sometimes have to turn the engine off to get into
reverse. So I checked around, and I found that the fluid level in the
master clutch cylinder was VERY low. But the problem did not go away
after I added fluid, so I assume that some air must have gotten in.

But I can't figure out how to bleed it. (I have two shop manuals -- a
Haynes & a Chiltons, I think -- and my system doesn't look like any of
the pictures in either book.)

The slave cylinder is a horizontal cylinder, on the left side of the
clutch housing, about 1 inch diameter x 4 inches long. It has a little
teat on the bottom, about 1/2 inch diameter x 1/2 inch long with a
setscrew on the bottom end, and a little hole on the *side* of the teat
-- right where it joins the main cylinder.

When I loosen the setscrew and press the clutch pedal, fluid comes out
of the side-hole, but there is no way you could attach a bleeder hose
to the teat without blocking the little hole.

The shop manuals talk about the 94 wranglers having a "sealed" clutch
system, but it doesn't make any sense to me that there is provision for
adding fluid, but no provision for bleeding.

Thanks in Advance!! john w.

On some of them, you are just supposed to sit there like a fool pumping
the crap out of the master until all the bubbles stop coming to the
top. Someone here should know how far you are supposed to pump the
pedal, it might only be 1" or so, I don't remember. It has been posted
about here before.

I just have someone push and hold, then I open the bleeder, watch the fluid
come out, close the bleeder before the fluid stops. Be careful, the first
few can have lots of air and it is easy to get sprayed in the face. Repeat
about 10 times and you are good to go, all new fluid in everything.

Re: How to bleed clutch slave cyl, 94 Wrangler ??
 

I've replaced a couple of those and usually "bleed" them before
bolting them into the bell housing so that they can hang straight down
(all the air goes to the top near the bleed hole). The last one I got
didn't even have the bleed hole drilled through and I quickly figured
out that it wasn't needed. The clutch master has no reverse flow
valve in it like a brake master would, so the air just slowly bubbles
up through the pipe. This works well with the slave off and hanging
straight down but I'm not too sure how well it would purge if the
slave were level - looks like some air would be trapped. Maybe
parking on a downhil slope would help. Pumping seems to get most of
the air out, anyway, but pump slow. Fast down is ok, but release
slowly to let the air work it's way up the hose. Otherwise, just park
on a steep downhil and go have lunch while the air bubbles up.

Anyway, if the fluid was that low, you have more problems than just
bleeding because that fluid went SOMEWHERE - I'd bet on a leak in the
master cylinder.
