I just bought a 96 PC50uu2 excavator that seems to have a lack of power issue. We noticed it when trying to push our stuck dump truck out of a ditch, the truck is a small ford f800 five yard that was empty at the time, and the excavator couldn't do it, it would not spin the tracks, just seemed to not have enough power. This size machine should push that small truck out of that situation no problem. We tried putting the bucket against the truck and pushing with the tracks, no dice, then we tried pulling the machine close to the truck and pushing with the boom, no dice,..... so the power issue does not seem to be isolated to the tracks or boom. Also noticing it does not have the power it should when digging. It is an older machine but it should have more power than this.
First thought was hydraulic filter, changed that along with fuel and air filters. No luck. We are running the machine at full throttle. Does this sound like a hydraulic problem or engine output? No dealer in my area to take it to. Any ideas could I get the hydraulic pressure tested?
thanks very much
