Hi!

I have a Poclain 75ckb where the swing stopped working to the right side, but working fine to the left side. When I move the control to the right I can hear a sound from the pilot hydraulics (in the control stick) sounding like the oil is working against the safety pressure valve (or something). I am not very experienced with fault serching on hydraulics and was hoping to get some help on how to proceed to locate the problem. For example where to mount pressure gauges to see if the hydraulics is not operating correctly or if the swing motor has failed.
