Yes I have. It ended up being all the o-rings on the spool valve on the hydraulic pump were hard and falling apart. I replaced them with what I had and it was pretty good but it does still act a little funny so I was trying to get the right o-rings from Daewoo but they said you have to buy the full pump rebuild kit to get them and it is $400.00 so I might have to bite the bullet and get it to fix it completely.
