so my case 60 XT. has a hydraulic problem in the main boom valve. Tracked it down into one of the two counterbalance valves. Neither are available from case. Trying to decipher who made the valve for case. Doesn’t appear to be a Parker or sun numbering system. Entire valve assembly unavailable from case also Anybody have known good part number to install? Case number off my valve. 446619a1 Number stamped into tamper proof cap. 1hk65. 1cex20262-1 Next one case # 440571a1 Stamped into tamper proof cap. 1hk03 1cex20262-2 Any ideas who made it, where I can buy a similar one?
Well I see no one knows about this..... Numbers don’t cross to anything. Sun has no clue about it, not Parker **** Got a used valves assembly that had a different style counterbalance valve. Also got a new old stock entire valve Assembly
