Further to my question below re: hydraulic/case drain testing:
I could be off my rocker, but I think I remember reading on here years ago that there was an alternative filter for the 2-85's and 2-105's. Rather than the conventional filter with the paper element, it had a fine-micron rated screen. This could be used on the later 85's and 105's that had the PVE pump, which had a higher flow rate than the earlier PVB. It was supposed to be good for folks who used thicker/universal hydraulic fluid in their systems. If I remember right, someone on here said the regular paper element is too restrictive for the PVE pump at max flow if using universal hydraulic fluid, can cause excess heat, and possibly be restrictive enough for the pump to cavitate. I'm not sure I believe it would go so far as to cause cavitation, however, as I think this system has a bypass. But I also don't pretend to be an expert.
If this is correct, does anyone happen to know the part number for the alternative filter? I wouldn't be too concerned if I was using the original Agco filter, but looking into it I see the Napa equivalent I'm using has an even finer micron rating than the Agco one, so I'm worried I'm way too restrictive for my PVE pump with the Hy-Guard fluid I'm using.
