Hi Fellas, New to the forum and in need of some help. I've got a 2004 S185 that I picked up used, got a bit of a deal because the loader arm drifts, only while hydraulics are active. I though easy fix, wil be a seal in the spool valve. Well I pulled the block out, checked every seal on that thing, replaced the spool seals just to be safe and the damn thing still drifts. I'm thinking it can't be the cylinders otherwise it would continue to drift with the machine off or Hydraulics locked out. I don't think it's linkage or actuator calibration because you can hear fluid passing if trying to hold the loader arm steady. Is there some component to a bobcat that I'm missing? Or did I miss something in the control valve block? I sure hope I don't have to dive back into that thing, what a pain to get in/out.
