Greetings,
I've got a strange one with the clutch system on a 87 YJ (258 5spd
puegot tranny - internal slave)

Around a year ago I had the slave cylinder replaced (and while they
were in there the TO bearing, clutch plate..the works).

Roughly six months later the clutch wasn't disengaging, no apparent
leaks, so I decided to replace the master cylinder. Hey worked great -
for about 3 months.

Replaced the MC once again - problem solved - for about 1 month.

I thought maybe it was that the clutch wasn't bled properly, so I went
through a series of bleeding - works for a day or two then not. Now
the bleeding just to get it to run for a few days isn't even working.

And as before, there appears to be no lose of fluid/leaks.

Anyone?

 

It either leaks or the master cups are not holding again, seems
hard to believe unless something other than brake fluid was used, which
means you have to replace the slave again, too.

Don't know where you're getting your MC's, but certainly seems to be the
problem. If there is no fluid loss it can only be MC. If pressure is lost
anywhere else the fluid will end up on the ground. The MC is the only
place the fluid can bypass the piston and end up still in the reservoir.
Make certain that there are no return springs on the linkage/pedal that
don't belong. Pulling the piston back rather than letting the fluid push it
back can introduce air past the seals in the MC.

It's much more difficult (for me, at least) to bleed a clutch than brakes.
When you mash the brake pedal down & it feels solid your done - but you
obviously don't get that with a clutch. Call me lazy.............but I
worked @ a Ford dealer in 1966 when I received my draft notice. I sold my
power bleeder to a friend/fellow mechanic for $20.00 (thinking that I would
never need it again) & then spent it (and then some) on wine, women & song
that night...............I know, I know - I digress

I finally bought another one a couple of years ago. I put 2 or 3 qts of
fluid on the floor, "bleeding" the clutch on the Explorer, became rather
frustrated, bought the power bleeder & 2 burps later was done. It cost me
about $200.00 (10 x what I sold my old one for) - but I think I saved that
much in brake fluid.

I'm thinking....maybe bad master cylinder, maybe bad slave cylinder, maybe
just more air. A man never has too many tools. Find a power bleeder - see
how long that lasts (also might help you find a leak you didn't think you
had) - then look @ the master cylinder & slave cylinder
