My 68/69 580CK loader bucket can be tilted up, but will not tilt down. Every thing else is ok. I can raise and lower the bucket, just won't tilt down..the only work done recently was the small side cylinder was rebuild. The problem began after that. Any ideas on what the problem is?

sounds to me like a blockage at the ram or the pipe,take the pipe off the ram and check for obstructions it may be a piece of the hyd hose blocking it,you could also blow out the hose to check it too. has there been a new hose fitted to this ram? there may be pieces of rubber in it. other than that i'm not sure hope this helps.

If the problem occoured after you had the cylinder rebuilt I would borrow a couple JIC caps and disconnect the Hydra Leveling cylinder completely at the valve. That would eliminate it as the cause, It is only a slave cylinder and will not affect the bucket roll except to defeat self leveling, however do not plug the lines at the cylinder while testing as any up and down movement of the loader will (not maybe) create pressures that would destroy something. Does lever travel seem ok in both directions on the bucket spool? mEl
