clutch experts please

okay i have another thread called xj won't start.... and i was talking about how i put in a new clutch.
i didn't change any bearings or anything, but i did replace the rear main, so i took the flywheel off etc. i put everything gback together, used the clutch alignment tool, it worked fine and i put the tranny back on. i bled the system quite a bit, to get rid of old fluid and to make it work (duh).

well, the clutch doesn't work, the jeep won't budge. i am not sure if it is a ax5 or 15 tranny but the bleeder is on the pass side and the connector is on the driver side. when i was bleeding it i noticed that those lines are kinda loose (they are connected inside the housing) , like i can move them around a little. i imagine there needs to be some play in them but do you think something is screwed up?

what else is necessary to make the clutch work? my dad has done a lot of clutches in his day... the day of cable clutches!

let me know what you think? i don't want to take the damn thing back apart, but i will if necessary.

thanks,
nate

Are you saying that the piston on the hyrdo clutch isn't moving?

 

[N-Smooth]

hmmm

yeah it would seem that way. i just didn't put it that bluntly.

When you bleed it are you still getting air out (or were you)?

When you say the jeep won't move do you mean it is acting like you always have the clutch pedal pushed in? If so you have other problems besides air in the line. Parts are installed wrong or the wrong parts are installed.

Like the clutch was put in backwards.

Something like the guy who put his front end together and the calipers would not fit

umm

it is a centerforce dual friction and i put the side that said flywheel side against the flywheel... seems pretty self explanatory.

there wasn't really air coming out when we were bleeding, but the fluid was really dark so i bled it a few times. the book says to press the clutch all the way in and then open the bleeder, i was opening the bleeder and then pressing just like with brakes... it shouldn't make a difference though cause if fluid is coming out fluid is coming out right? i am going to bleed it more tomorrow, i was going to tonight but i had to replace my dads motor mount in the bronco... PITA!

maybe the push rod needed to be greased or something.

any more suggestions?

hey

what kind of idiot would put the brakes together and not have the calipers fit???
btw that was not my fault, the caliper bracket was bent! i fixed it though.

Your problem is not air in the line it is wrong parts or parts installed wrong. Air in the line will cause the jeep to continue to move when you push the pedal(clutch disc will not disengage from the flywheel). If the jeep will not move when in gear and the pedal is out it is something else(Clutch will not engage flywheel). There is no adjustment possible with that hydro setup is there? Some aplications can use either a high or low finger diaphram pressure plate. It is posible to use a high plate with a release bearing made for a low plate and have the problem you have. This might not apply to your application. It is also possible the release bearing may be jamed up on the tranny input bearing retainer not letting the pressure plate engage.

I have to ask why you would spend the huge bucks on a dual friction to run it behind a 2.5?

ok

sounds like i will be taking it out again... that sucks! i'm going to screw around with it first though.
well my brother bought the xj from my cousin a couple years ago, and he gave him an extra clutch. i bought the jeep off my brother and then i found out what a centerforce was and i was stoked. the clutch didn't even need replacing, it worked fine, but i took out my t-case and figured i might as well replace the clutch while i was at it. there was already a centerforce in there, but a couple of the fingers were bent and it was kinda worn. i didn't know that this one was a dual friction until i took out the other one and noticed that it is different on the two sides and this one is the same.
thats what a df is right? the same thing on both sides? cause on the old clutch the material was all over the clutch side and just on the "corners" on the flywheel side.

i guess i should have replaced the bearings and junk...my own fault.
thanks,

yeah

works now... i bled it some more and then just pumped it quite a bit and i think it was stuck or something but i must have dislodged it cause it works like a charm!
