I was using my BX 1860 yesterday with the front end loader and a weight box when it suddenly started spraying lots of UDT Fluid from the back. The fluid is coming from where the U shaped tube coming from the three point control valve connects. spraying out around the flared fitting on the left side. The fitting was tight, I removed it and inspected it and reinstalled, it is still leaking. seeping out at idle and spraying when the control valve is used. I can't find a split or crack in the fitting or tube. any ideas what is happening?
