I'm having trouble moving my 7030 Allis. I can get it to move after playing with it. I put a pressure guage on the power director Transmission. The pressure at the regulating valve reads 145-150psi all the time except at idle. It should read around 200psi. I can put shims in to the pressure regulating valve to get to 200psi or do I need to look more closely at my Gerotor pump? My other Hydraulics, like moving hydraulic cylinders work fine. But when I look at the site glass for the oil in the rear end when the tractor is running it is all full of little air bubbles. The oil turns almost white. Last summer I dumped all the rear end oil and filters and put new in. Thinking I might have some water in the oil. I still get the bubbles and the tractor is still hard to move. Where do I start, shims first or put in a different pump? Thank you and have a great day.
