pfrederi 17,866 #29 Posted March 7, 2021 (edited) The clicking noise sounds fairly normal it is the limited slip differential working. Did you look at the diagnostics in the manual?? Can you push it with tow valve closed.? Is the motion control plastic plate moving the control arm on the pump fully??

squonk 41,321 #30 Posted March 7, 2021 The whining sound to me is an indication that all linkages and keyways are fine. It's the hydro struggling to move the tractor. May be time to find another trans. Years ago my C-160 would out of the blue start whining and bucking all over the place and erracticly. After checking the springs I replaced the hydro motor. It's starting to get a bit tired now. I have a complete unit in the shed ready to install when the day comes. 1 Share this post Link to post Share on other sites

I found a complete tractor that runs but burns a little oil for $100. No implements. But he says it moves good. He’s a friend of mine so I doubt he would sell it to me knowing what I need if it wasn’t any good. 1 Share this post Link to post Share on other sites

Over time these springs give out and the fluid pressure will fight itself and the tractor won't move well or not at all. Take a look at the Sundstrand manual. https://www.wheelhorseforum.com/files/file/24-transmission-hydro-sundstrand-sm-492-4206pdf/ Share this post Link to post Share on other sites
