Cam Plate On an Auto

[1973Auto 80]

Hello all. I posted this question sometime ago concerning the pivot ball popping out of the plastic cam plate. Well I fixed it before and it worked, then I fixed it again, and again....see a pattern here. I put in a new cam plate, very difficult because there is no room to jockey the plate around. After I get it back together , dive it and for some reason the pivot ball keeps popping out!!!!!! Before I do what I don't want to do, put a rod in the eccentric cam hole and drive it that way, I am looking for any ideas/solutions before I go that route. I had to file down the pivot ball and the cam itself because the ball was hitting the cam. Tractor is a 1973 auto. Thanks in advance.

Did you happen to check the transaxle mounting plate on the tractor frame?

If it is cracked or broke there can be alignment / engagement issues at the cam plate / DCL ball.

Terry:

No for the reason that I do not know what that is . Can you post a diagram to walk me thru it .

Where Terry is talking about is under the tractor, the large plate it is part of the frame, and the trans bolts to it with 4 bolts, if they are loose, or the plate is cracked and the trans not lined up with the back of the frame it can cause problems.

Thanks kelly: I went to parts tree to find the plate in question (can't find my manual) for some reason I can only get the manual for a 16hp auto, hope the assembly is the same. Can you tell me what section it would be on. I copied and paste all of them from partstree. Thanks for the help.

Open the first link you posted, its the square plate on the far right of the diagram

4 bolts pass through it to hold the trans to the frame

ive had to shim the ball towards the cam,but you say its too tight,definatly look at the mounting plate and frame for bending or cracks
