76 4430 quad had minor traction clutch repair 1500hr. ago and since then its very hard to take off smoothly. Clutch was still in good shape but changed brgs as we were actually repairing quad pack and tractor was split. Perma clutch measurement were fine. It was smoother before. Could it have to do with pump pressure? Or maybe its because I just turned 65.
 
My thought is the adjustment of the pressure plate assembly is uneven, if one finger is a bit tighter than the other two you will get this kind of result, I'm assuming the correct set up tool was used.. The other thing that can cause a 'Jumpy' clutch is a weak or broken clutch operating valve spring, located on the left side of the clutch housing..
 
Thank Tim S ,The fellow that helped me on clutch repair was very maticulous and yes he used special tool for clutch setup, but valve spring I will definitely check out , thank for the advice.
