Guys you helped me once before, I am hoping you will help me again. I am having 3pt issues with my 640, it all started when I lost my 3pt lift capability and had to bleed the pump to get it to lift. This problem snowballed into every 2 - 3 days having to bleed the pump. After doing some research I decided my best bet was to replace the hydro pump wobble shaft and seal. I took the pump apart and found slight wear on the wobble shaft, I replaced the parts and put the pump back together. One thing I must note, I was given the incorrect oring (Small oring) for the hydro pump to manifold seals, I reused the old small seal and used the new square cut larger seal, but everything appears to be sealing good, no drips from the manifold. After reinstalling the pump this morning, for the life of me I cannot get this thing to stop pumping bubbly hdyro fluid out of the bleed hole. Tonight I installed a hose barb and clear tubing and pumped 1 gallon of fluid through the pump back into the UTF jug 3 times, (stopping to top off the reservoir) for a total of 3 gallons through the pump, still bubbly. What am I missing or doing wrong? I have a single spool remote valve, and some pretty long hydro lines going to my plow lift cylinder on the front of the tractor. Please help me....
