I have a IH 656 (non hydro) with a hydraulic fluid aeration problem. I completed the following trouble shooting steps. Any suggestions would be appreciated.
1) Removed third link - major aeration in the fluid occurs rather quickly after start up.
2) Checked rubber return hose and it was kinked and had ruptured but under fluid level.
3) Replaced hose and let tractor sit until foam no longer showed up in fluid.
4) Started tractor aeration was persistant.
5) Over filled with 5 gallons of hydraulic fluid.
6) Started tractor aeration was still persistant.
