If you can provide pictures that would help assist us in giving you ideas of what needs to be done. Like Ken said, spool seals are cheap but they can be hard to install without pulling the control block out.
ok where is the best place to order the parts
Your local dealer will have a kit for this, i can't tell you the price though. You could get the parts from a hydraulic seal shop but if you get the genuine seals you know its rite.
I changed out the spool seals with pump in place. No way would I try to remove pump. Hardest part is correct order and direction of seals and springs. I took spools to dealer and parts man stacked parts in order. A week later I had to re-do one spool as I blew out seals. I was spreading stone with bucket tilted verticle when I bounced and dug teeth in ground. Yes, I knew better
