I was raking hay with my Oliver. All of a sudden, the fluid started blowing out of the reservoir. The fluid will not stay in the system and blows out the reservoir if you run the motor at all. This is a standard Char Lynn add on power steering system with an under the hood reservoir and Eaton belt driven pump and has been on the tractor for all of its life. Never had any problem before leakage or otherwise.
Any ideas on how to trouble shoot or repair the system? Is the pump sucking air somewhere or just shot? Are installation/repair manuals available ?
Any help would be appreciated.
Thanks.

Thanks to Glennster for the Char Lynn Manuals.
After reading them, I found out the cause was a stuck relief valve in the Eaton pump.
I took the pump and reservior off the tractor. Flushed out each including the torque generator and the hoses. The oil was dirty and I flushed until everthing was clean.
I cleaned the reservoir filter. My reservior had a metal fine mesh filter versus a paper filter. It had a lot a dirt in it too.
I removed the relief calve by tapping on the pump casing with a wooden mallet. Cleaned the valve and flushed the pump.
After re-installing everything and following the instructions on removing the air, the power steering is working properly again.
