I've got a problem with a Komatsu PC300-7 governor control, in engine rpm auto, the engine rpm works fine with any operation of the hydraulics (bucket, boom,stick and swing) returns to low idle when not used, however when you use travel forward or reverse either track/s, the engine rpm drops low idle then hi idle like hunting all the time while the governor control knob is set 100% turn the control to about 90% or below and it works fine, turn the control knob back to 100% hunting starts again, you can see the throttle control linkage engine side, going from full rpm to idle then back to full rpm only when travel is activated and throttle set at 100%.
Anyone come across this before?
