Have a Farmall 504 that has a very loud squeel that seems to be coming from the steering oil cooler in front of the radiator. Don"t think the cooler is plugged because one line seems warm and the other seem a little cooler. Put a screw driver (to listen) on the lines and can hear the squeel for sure. Took the relief valve apart that relieves if the cooler is plugged and it seems to be in good shape (not plugged, or broken) all hydraulics work good, just that anoying loud squeel. Changed hydraulic fluid and filter (oil was pretty bad). The squeel seems to go away after the tractor has been run hard (4-5 hours) and everything gets really hot but will return periodically. I have the IT manual but just can not figure it out. Thanks for any imput.
