Found out this afternoon that the lever that is to operate the rod and arm for tightening the PTO pulley is not attached to the rod. The lever, block it is attached to, return spring are all free and operating A-OK. The rod that is to move the tension pulley does not move with the arm. The parts breakdown that I have does not show how those two parts are held together or where that point may be. It shows 3 roll pins that hold the three flange bearings in place as well as the pin the return spring hooks on. Where/how does this rod and engagement block join? It looks like the transmission cover has to be removed to even get to where one can see it. Any advise is greatly appreciated.
