Hey there,
Im currently working on my 78 JD212 and I am having issues with the variator. There is no adjustment with the lever. Its like it is pushed all the way forward(in high) all the time. There is nothing putting any tension on the variator pulley, thus causing the belt slap around violently, and ultimately resulting in it jumping. Now the variator pulley has a peculiar knocking sound coming from it at any speed. It sounds like a bearing yet there is no play in it. The transaxle pulley is not bent. The idler pulley jumps violently up and down while it is running. There is some where on the pin the idler pulley mount to resulting in- in and out play but this is not effecting the up and down movement of the pulley. Now I also have a 77212 and that works fine. The variator lever is connected but it never puts and tension down forcing the clutch back to slow it down and i cannot for the life of me see anything that is binding being i have all sheet metal off of tractor. Any ideas from someone who might have run into this problem before?, it would be greatly appreciated.
