I took off the loader, it was kind of a pain without hydrualics to change pressure on the pins. I used wood blocks and 2 bottle jacks then backed out the tractor away from the loader. Then supported it with cinder blocks.
As per an online serive manual I found, I switched the box lever from pointing to "S" and opt it to the "O" position, connected the 2 hydraulic hoses that were quick-disconnect fittings. hey were a beech' to connect even after cleaning and spraying them down with WD-40. Finally got it, fired it up and wah-lah, my back grader works. It goes up and down real smooth. Now I just need something nice and heavy to mount on top of the grader blade for extra weight - so it'll dig into the ground. (old engine block, etc)
I'll tackle the loader issue and valve assy later. Hell if I have to I'll just put a few single levers on it to run the loader positions. For the boom, up and down and another one for the bucket to tip both ways. It'll be pretty rinky-dink but functional. <shrug>
