Farmall A clutch

Finally got the A started. Now it won't go in gear. I have nearly all the free play adjusted out of the linkage and it just grinds.i think everything was put together right. Not sure if I got the right parts though as we bought an engine with a clutch and used it with the old flywheel. I will take a closer look tomorrow. Anybody got any ideas?
 
put the tranny in any gear then push the pedal down now hit the starter that will show you if the disc is glued to the flywheel
 
I just put it together so it should not be stuck. I tied the clutch pedal down, put it in forth gear and turned the hand crank. Tractor did not move. Put it in first gear, turned crank and tractor moved. When I get some tires I may just drive it and let it burn in.
 
If the clutch shaft splines are worn (even a little) the clutch plate (in a different tractor/engine clutch combo) will hang on the
shaft and cause it to be pushed into the flywheel. This drags the disk at engine speeds, causing the trans to grind. It may be
necessary to polish the shaft to eliminate steps or burrs on the splines. Jim

Thank you. I think I checked the splines and slid the disc on it. I may have missed it. The only thing I didn't check closely is the pilot bearing. Just had a quick look and it looks like the pressure plate is moving plenty far.
 
If the driven disk was tweaked a bit when closing the split, it can drag due to the friction material touching the Flywheel or
Pressure plate. The pilot bearing is also a possible friction point. Driving it by putting it in gear clutch down (clear assured
distance to stationary objects.) and driving it around using the clutch often in 3 and 4th gear. Jim
 
After I posted last it dawned on me that I may have tweaking the disc. I was trying to put it in by myself when a pry bar fell and hit the release on the hoist.
Hopefully it will free up but looks like we may have to split it. Won't take long at this point. Thank you for the help.
 
Did you by chance install if up side down?? As in the side that should go to the flywheel is now going to the pressure plate?? If you did it will not release as it should guess how I learned that one
 
(quoted from post at 11:30:21 02/07/18) Did you perhaps install the pressure plate backwards?
I have the hub out if that makes since. I may have bent it. When the hoist went down I had the engine in my hands and let it down easy but it was hung up on the shaft. I had to let it hang there while I jacked it back up. We have another clutch. If it doesn't free up we will try it or get a new one. At least it's a easy one.
 
May not be your problem but years ago I needed a clutch for my Super C on a Sunday, More snow coming didn't want to wait, got a decent looking one at the local junk yard from an A. Wouldn't go into gear like yours, fingers on the pressure plate didn't have enough travel so I adjusted them out, working through that hole on the bottom, using three hacksaw blades taped together as a gauge to the throw out brg. to get them close as I could to even. Worked good for over twenty years, put a new one in about three years ago just because, but it didn't really need it. If you happen to have it out throw both press. plates side by side and compare finger height.

I did rough measurements on them before I started. That doesn't mean they were right to begin with as it was a non running tractor when I brought it home. Throw out bearing is up against the fingers now. I am suspicious of the pilot bearing as we had to draw the last half inch together with bolts. It didn't take any pressure though so nothing was forced.
 
Having to use the bolts to get it closed up is NEVER a good thing and good chance you have either bent or broken the clutch disk or maybe messed up the pilot bearing
