Ok I'm boggled...Replaced clutch with a RAM 10.5" stock replacment, in order to shift into gear I have to adjust the clutch so that the throwout bearing rides on the p/p fingers with pressure. The clutch does not slip but needless to say the bearing does not last 1 night. The previous (exploded) clutch worked and adjusted fine. Setup is oem lightweight flywheel, steel scattershield with non adjustable ball, wildwood push slave and wildwood pedal. Any suggestions???????

The things I would check for first are obvious: air in the hydraulics and the clutch fork not seated properly on the ball. There are two different length throw-out bearings. If you are using the short one, you might want to try the long one.

3 finger clutch uses a round faced brg, which is longer also

diaphram clutch uses a flat faced brg which is shorter.

is your fork on the ball in the bellhousing correctly?? if it is hooked but pushed in towards the trans too far you wont get enough throw to work the clutch. to check it see if you can pull the arm out away from the clutch, they get hung up in there really easy..

already checked for air in system and the arm is seated on the ball. I forgot to mention that this is the second bearing due to this problem

I figured that you had, But I put it in there because it was too obvious not to mention it. My son had similar problems with a triple disk and the longer throw-out bearing fixed it. I don't know why. We got busy on other things and never put any thought into it. I was a little hesitant to post a reply because I can't explain why it fixed it. Maybe someone will chime in with an explanation. I hate suggesting someone pull a tranny without being able to explain why.

Triple disk clutches use a shorter stack hieght than single. You have to make up that space. You can use a really long ball stud and relocate the push/pull slave or easier yet, use a longer bearing.

Okay after some thorough and carefull investigations, the findings reveal that the throwout bearing is only traveling 1/4" according to RAM it has to travel 1/2". The only solution I can come up with is a master cylinder with a larger piston to push the slave further. Any other suggestions?

disconnect your slave from the clutch arm and see how far it moves with no load. my pull slave goes all the way in pretty much. Do you have a 3\4 inch master seems like from memory thats what they all call for.

It sounds to me like your fork is not on the ball exactly right still. The fork is pushed too far towards the center of the car.

When I put mine together I have to pull out on the arm awfull hard to get the fork to line up with the ball exactly right. When its not on the ball but still seems right it only moves the throw out brg about a 1\4 inch because it doesnt have the right leverage ratio.

I am familiar with this problem because it gets me every time I change motors. I jump in to test the clutch and it never works. I know you said its right but if you cant see it easily I would double check it again.

Did your clutch come with a brg? is it the right one? long round face or short flat face as I mentioned above?

ok I got a ? you say push slave, so is it like a factory push slave and mounts tight to the block??

or did you mount it way out on the end of the stock type fork?

If a push is way out on the end it may not move far enough?

I allways use a pull slave.

Yes it is a push slave and it pushes on the end of the fork like a factory setup.

I looked at mine today, and my fork moves at the end about 1.5 inches easily.

Did you check your push slave for how far it pushes without being hooked up yet?

I think your idea of a larger master, or a smaller slave cyl is about the easy and best fix for this problem.

I don't know a whole lot about this set up but I do remember seeing in one of the catalogs that some of Rams equipment uses a 7/8 ths master cylinder instead of a 3/4. Check with Ram.
