I posted here maybe a month ago about problems I was having with a 45 loader that I mounted on a JD 60 that I bought recently. I had been noticing a lot of hissing noise and the loader leaked terribly out of the front of the cylinders. I finishing installing the repack kits from JD today and also replaced the orings on the ends of the oil suction tube from powrtrol to pump.
I put oil back in the tractor (maybe 1.5 gallons) and fired her up. The loader lifted to about waist height without a lot of noise so I figured that was a good starting point. I got off and put another half gallon or so in and she lifted it another foot on the next try. That was the high point. After putting a little more oil in the pump starting making that vibrating hissing noise each time I actuated the lever and the loader lifted lower and lower on each subsequent actuation until dumbfounded I gave up.
The loader is hooked up with four oil lines, the front two closest to the nose of the tractor being tee'd into the top side port of the powrtrol and the back two lift lines being tee'd into the bottom side port. Scratching my head here--the loader has all new lines but I did pinch one of the lift lines pretty good when I drove into the brackets. I though it might be damaged but since it held oil I figured it must be okay. Could I have a poor pump, air in the lines, damaged couplers/hoses, or powrtrol issues? Thanks,
Pete
