Hey Bud.........I sent you a PM....LONG....trying to explain what I did....Basically you get a shim kit to increase or decrease the pressure....You also need a gauge to be able to see what you are doing as you work with the shims. Usually you just put the shims in the regulator, I think it's called, which is located on the pump; but in our case B7610, the regulator is over on the arm where all the hydro lines go in and out. I forget which one so that is why I gave you Brian at Messick's number as he is totally helpful and will give you the schematic in an email and perhaps talk you through the job......
You pull the hydro line, something tells me yellow, and take out or put in the color coded shims to increase or decrease pressure.......Be careful because later I blew 2 of our OLD hydro lines when working.......But you can increase the lift capability of the loader.....Good luck Bud......God bless.......Dennis
