Hi all,
I've got a hydraulic question that I think needs an answer from someone who really knows hydraulics.
Tractor: John Deere 1010 Gas, 1961, Gear Driven hydraulic pump with dual cylinders in the quadrant
The Issue: The tractor currently uses metal lines to send the fluid from the pump, to the quadrant, through the quadrant, and back to the pump. Originally, there was supposed to be a screen inside the larger diameter return line that was used to filter out debris. My tractor does not have this, and I would like to add some sort of filter. I have tried numerous part sources and salvage yards, but nobody has this part anymore. From talking to someone familiar with the part in question, he suspects that most of them ended up disintegrating inside the line, which is why there aren't even any used ones.
So, what I'd like to do is (1) replace the existing metal lines with hydraulic hoses. I am very confident that this is feasible and can be done easily. However if I'm going to do that, I'd also like to add in a way to filter the fluid. My thought was to add in a hydraulic filter housing on the return line. The line is in an ideal position to add in a filter there. My concern with doing this is that it may reduce the flow rate in the return line. In my particular system, the return line is not high pressure, but I am still worried about it regardless. Is it safe for me to do this, or do I risk tearing up my pump?

In the early 1950s my father bought an Allis Chalmers B and I used it for all the row crop work with the mangolds and potatoes, rolling and the haymaking on our farm. The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
