I have 1965 jd 3020 diesel. I have a loud noise coming from the hydralic pump.It sound likes
a squealing noise, gets louder vas rpms go up. I
also feel a pulsating in the hyd lines, but the hyd fluid is not foaming and all hyd operate ok. Any ideas fluid and filter been changed no difference

Did you clean sump screen? Load squealing could be a internal high pressure leak or stroke control valve.
