Bobcat 843 high flow hyd issues

[Redbear76]

Hi I brought a 843 high flow a while back an I found it won't lift a full bucket,tested it at the bucket aux ...1500 psi..thought the pump was knackered so tested the pump and got 2500 psi.,so I thought the port relief may be tired so I replaced it....but still not lifting full bucket.. Question.. There is a relief valve on hyd pump I gather its fine since I got 2500 psi?. There is one port relief on control valve the I've replaced.can't see any more.repair Manuel shows another one on control bank but I have a hose coming out of it that heads to 12v aux diverter so to speak.. Any ideas on anything to look at..I'm fast learning my way around the system but I'm still stumped any help would be great thanks

The relief vavle is on the control vavle. An 843 with highfow, huh, never saw one. Is it an 843H?

I'm guessing it is since its setup matches the 843h in the 843 repair Manuel .took a while to figure that out

In the manuel it shows a main relief on control valve like you say.on my machine there's a half inch hose coming out of the same place
