Over the winter i installed remote hydraulics on my L355SS. Installed a 4 spool valve with open center and power beyond, 2 spools are dedicated for tilt and top on the three point and the other 2 are for remotes. I tapped into the main pressure line from the hydraulic pump for the pressure and power beyond, and tapped into the pump suction line for the return. After I finished it I used a box blade to grade the driveway, just to try it out, and it all seemed to work perfect but now, 3 months later, I'm trying to use the same box blade to level a building site and something is wrong. If I use one of the spools for the top or tilt just a little everything is fine but if I move the spool valve full travel and use all the pump volume/pressure the hydraulic shuttle clutch disengages and tractor stops moving, when I release the spool the shuttle bangs back in hard and the tractor takes off again.
I'm wondering if this is a design error from the way I tapped into the hydraulics or if there is a check-valve on the shuttle clutch that's bad or maybe something wrong with the shuttle clutch? The shuttle clutch seems fine when used from the shuttle lever and it engages smoothly but when I use the remotes and it disengages, when it re-engages it bangs hard, so hard I'm afraid it will break something. For now until I get this figured out I have to stop the tractor to use the remotes.
I attached some pics of the install so maybe someone could figure out what I did wrong. Let me know if there's anything else you would like to see to help me fix this.
