Gentlemen! 68 dart 360/833 change over from auto. Everything mew/rebuilt from Brewers
with all new component z/bar fork,pedals #734 bellhousing//hurst comp new shifter. Everything bolted up right. Clutch new 10.5 23 sline disc centerforce street clutch. Clutch
disc would not release when running. Thought I had disc backwards. It was on right.
So put it back together. Checked throw out bearing and I think clutch rod throw out
brearing not moving deep enough to move fingers deep enough to push fingers far enough
to release clutch disc! What is your thought? Everything is new from brewers!
 
Does it look like the fork fingers are close to slipping off the throw out bearing when the clutch pedal is pushed down?
 
On my 4 speed swap the clutch fork pivot in bellhousing was too short.Found out there was a taller one in my other bellhousing and it solved the problem.I was maxed out on adjustment with minimal throw out bearing movementAgain just my experience and I had no idea there was different pivots
 
Not sure if this helps, but I asked Centerforce what the figures are for my 10.5" Dual Friction setup, and they replied:
The disc will be released with an 0.030” air gap. Linear travel at the bearing is 3/8” to release. Bearing load is 500 lbs.
 
Believe it or not, there are a lot of variables associated with what you have just done. Those variables would be with almost all of the linkage from z bar to the throwout bearing. The pivot inside the bellhousing can't be crossed with the wrong or correct fork, it's pretty obvious if that were to happen. The z bar may have to be modified, do you have tti headers? You say that it's all Brewers, which fork do you have, 12 1/2 or 10 7/8" ?
And I don't suppose that you took any pictures of the parts that you put in.
 
The disc may be too thick..if that’s the case, you can use .060 thick hardened washers under the pressure plate to get the finger height up.
 
Thanks for the replies! I called centerforce. They said
it might take 3/8s to 1/2 in. release to push in fingers.
I hope this is it. Thanks for the info!
