I have posted a few times in the past few days about a 3 pt hydraulic problem. In summery I had a 3 pt that would not work properly. The o ring and Teflon washer were blown out . I changed the o ring ( part #15 63x5.7 and the Teflon washers . part # 19 a63x2). I took the piston and cylinder to the local seals place In Fort worth and the dimensions of the 0ring should have been 52.3x5.7. So I replaced the o ring and the two Teflon washers. The three point lift worked perfect for three operating hours. Now I am using a two row five foot disk and it will not even stay up long enough to make a corner. It will fall almost immediately once I let off the lift lever. Can you inform me what might be the problem? Thanks Robby http://www.johnstractor.homestead.co...dPowerLift.jpg
