cat hydraulics

Ok, so having a similar problem with hydraulics after replacing resolver valves. I have been using machine without any problems until yesterday. i was moving some stumps with the clam and lifting them up to move. one was fairly heavy, and it moved it fine, but shortly after that all loader, clam, lift and curl barely work at all. The hoe works fine except the swing seems slow and stabilizers. Any help would be appreciated. 89 cat 416 serial # 5pc08594
