I disassembled the draft control to replace the seals, including the position control eccentric (the shaft toward the right rear of the housing that has an o-ring on the inside and a snap ring on the outside). The whole job was a giant pain in the ***, especially the position control eccentric, because there is a snap ring inside the case on it that has to be removed & reinstalled that I couldn't even see around all the linkage parts.
Before I took it apart, I photographed the relationship of the draft control and hitch levers to the linkage inside, so I could get it right before I reassembled. So, I got it reassembled and started the tractor, and the hitch arms raised all the way up, and will not go down regardless of the position of a the levers. Very frustrating! This thing took many hours to repair and would take many more hours to get back apart.
Can anyone offer me advice on what is wrong? Could it be trapped air in the system? If so, where would I bleed it? I'm at my wit's end with all the time I have in this.
BTW, the common cure mentioned for curing leaks in the draft control housing is to remove the tall plug at the left front of the inside. I tried this about a year ago, and it still leaked badly. Running the tractor with the cover off, I could see that the oil could not drain fast enough through the hole where the plug was, so the oil level was still above the seals.
