sunday, went up and baled about 3 acres of hay. Half way done pan kicker started to barely clear wagon gate, looked setting was on 3 for kicker, cranked it up to 6, still same turn all the way up to 8.....no difference, now hitting top edge of wagon gate. So i check obvious things, belt tension, fluid level. all good, tuurn on tractor and pto for baler, walk back by kicker, hand trip the pan, it cycles fine. bale again, 2 bales its hitting gate. Leave running walk back again... Loud buzing from line to kicker control valvve. Hmmm... ok maybe pressure regulator is chattering, never replaced O rings inside it. Check them, replaced one, and cleaned out again. test ran tonite , was quiet at first before tripping pan.. trip, and buzzings there again, now i listen by pump on bottom of baler by flywjeel, NEW pumps noisey. got about 1200 bales thru baler, but pump runs all the time when PTO is engaged. so figure about 10>14 hours time on pump. Ran baler for 20 minutes per JD tech to break in pump before baling. All new fluid, new suction screen in tank, new rubber lines, control valve cleaned rebuilt, pan cylinder cleaned and rebuilt. theres steel lines that run length of baler under it for pump lines, i flushed them out with several gallons mineral spirits, and bleew out with air, and also brake cleaned beyween mineral spirit flushes. Flush was comingout clean when i was done.. all done before new pump was installed on baler. Guess i will have to call hydraulic shop order new pump, and see if they will warranty this thing.
