2005 ASV RC100 Track Skidsteer Perkins 100 horse engine. hydraulic over hydraulic controls. engine sounds good. operates with no hesitating or jerking. all smooth. no loss of power from engine or any hydraulic use. at idle everything runs quiet. increasing the rpms a little starts the pumps shaking with a vibration noise, then a 3/4 throttle the pumps will almost completely stop vibrating, then increasing the throttle a bit more will start what appears to be vibration again from one of the hydraulic pumps. does it when its cold or hot. sometimes the vibration stops or starts at different rpms. when using the hydraulics the vibration does slow a little. I have had it where I came to a complete stop and was at a low RPM and it was shaking and vibrating and all I did was lower the bucket about an inch and the vibration completely stopped. any ideas?

Also check the pump mounting bolts. I suspect that you will have two or three pumps on this unit so make sure they are bolted together properly.
