My Ford 5610 has two sets of rear hydraulic remotes. I am using one set to operate my front end loader. The remote has an operation lever that has to be moved from neutral position to operate. The lever will stay in position and the loader will operate great without a load, however when weight on front end loader and hyrdros get under a load the lever will kick out back to neutral position. If I hold lever back (in position), loader works fine. There feels like there is a detent to hold valve in postion. My question, how to repair, or keep lever in position while using front end loader ? Why will value not stay in position ? Thanks so much !
