OK I have a clutch linkage problem that is driving me crazy...... The scenario goes I had a 1-2 shift problem that needed addressed in my 70X. I ask a friend who he had taken his 4 speed transmissions to in the past for rebuilding, this is my first 4 speed car my friend has had several, so I went where he said as he never had any problems. I was asked to bring everything for the transmission- including flywheel, pressure plate, clutch, throw out bearing, shifter and all the shift rods. I received all my stuff back but my original clutch, pressure plate, throw out bearing. When the trans was in the car originally I had no issue with the z bar linkage adjustment. When the trans was installed after the rebuild the linkage had to be adjusted completely to the end of the threads just to get the clutch to disengage and still there is at least 1 inch travel between throw out bearing and pressure plate. Has anyone seen this before? Is the clutch wrong or throw out bearing? HELP ---------- Post added at 07:18 PM ---------- Previous post was at 07:16 PM ----------
So the throw out bearing is new? I may be thicker than the other. Order a Lakewood adjusable pivot ball from Jegs.
If anything I think I would need a thicker bearing to take up extra space between pressure plate an bearing.
This is a little like my problem. I tried a longer throw out with minimal results. I had to dig out my old clutch fork, which solved my problem. Do you have the bushing for the eye in your third picture? Mike Garrison sells those. ted
If you have a new clutch and pressure plate you must also consider where the fingers are oriented in space relative to your old set up. If we are taking the same bearing, it is the same as used in some older Vettes.
That is what I thought as well. The one installed after trans rebuild is a Hays. so I ordered a Centerforce to compare and measurements are the same. I think I still have my original clutch fork, but I am not sure. The one photo shows a measurement. Does you have one to compare?
Lets think about this logically. If the old pressure plate, T/O bearing and disc worked and the new parts don't, guess what? The parts he sold you are wrong.

Mine is all apart as we speak. Anywhere near Cleveland or Bath Oh.? More than welcome to come take a look or I could confirm at a later date.
I am near Brunswick so we are close. ---------- Post added at 09:04 PM ---------- Previous post was at 08:48 PM ---------- Can you give me measurement of fork to compare to my photo?
Pressure plate deepth is your issue. Traditionally Gm used two types of diaphram PP's.the bent finger was the high performance version and is used with the T.O. you now have.the straight finger plate is std performance and takes a deeper T.O..this sounds like your quandry.w/o more pix it's hard to say for sure.Bill
was the clutch fork changed by that guy? I know you need a Buick clutch fork as opposed to the Chevy design that is available everywhere. Perhaps the guy swapped in an incorrect fork.
I am almost certain this is the original clutch fork, or at least the one that was in the car prior to the rebuild.
I think Bill hit it on the head. Wrong PP. Probably has the bent fingers for use with the taller TO bearing
