Greetings Y'all, My 610 hyd control valves need rebuilding. After much grief, too many hours and a more then a few choice words I got the control valve assembly out of the machine. I am looking for the kits and I think all three spools. can anyone give me an idea on what the costs would be for the 3 kits and 3 spools? How about where to get them? Being retired I am in need of all the cost savings I can find. the control valves are made by Gresen. Is there a thread on this repair to help with the rebuild? Thank in advance for your help. Have fun, buckshot Ocala, Florida
