Trans. is in HELP

The most common for clutch to be engaged all the time is for the disk to have been installed flipped front to back. The taller side of the disk presses into the flywheel bolts. It won't feel forced together.
A few months ago I ran into the same problem but was caused by a different issue, I used a Hays disk in a McLeod pressure plate. The Pressure plates appeared identical. The only difference in the disks was that the Hays antichatter springs were just a little bigger.
No adjustment would get it to work. Only after pulling it out and looking more closely, (We even rigged it up in a press to check that it actually unclamped the disk) we finally saw that the 3 fingers on the Hays PPlate had reliefs machined in them to clear the springs. The McLeod fingers without the reliefs would jam into the springs before the clutch released and kept the disk spinning.
If I had a Hays PPlate and put the smaller spring Mcleod disk in it would have been no problem.
I wish you good luck so you don't have to pull it out.
