Guys, i have a ex 220-5 and it started moving slowly on the left track and developed a slow swing speed as well. The bucket seems slow. I hope this is a solenoid or sensor issue. Can someone give me some info on what it sounds like?
Hope I'm wrong but may be pointing to one side of the main pumps is failing, one side usually works the one track, slew and bucket, then other side will be other track boom and dipper. a flow test would clarify.
