Just got delivered on Monday, a Komat'su PC60-7 excavator with 6100 hours on the clock.
Works well overall, engine sounds very nice, hydraulics seem to be quick and responsive.
Couple of issues:
Only have one key. Not comfortable not having a backup key. And this key is worn. Hard to turn the key in the ignition. Can't get it into the preheat mode at all. Went to a bunch of places that duplicate keys and they all said this key is not in machine's program database. Where do you get additional keys made? I noticed that Amazon sells keys, but then that raises the question of how to get the key that matches your machine's ignition tumblers?
Second issue: Machine works okay for the most part, but it seems like the left track has less power than the right track. If I need to turn the machine in a tight space where there's little room to do a jump turn, I need to turn the tracks in opposite directions. The right track runs, but the left doesn't unless I push the right track lever a bit in the same direction as the left. Going in straight lines is no problem.
Third issue noticed today: Oil leaking from left side of engine compartment. Oil pooled on floor of engine compartment near the PPC Shuttle Valve. Didn't see any obvious leaks there. But oil dripped onto my left track and there's a trail of oil on the driveway. This after using the excavator to push over a small young tree (about 3-4" trunk dia) with the boom extended and the bucket and arm extended and just driving the tracks forward a little at a time. I'd estimate the contact point was about 10' up the tree trunk.
I was not aware of any oil leak prior to that.
Inspecting the engine compartment, I see no visible leaks. I even tried starting the engine and operating one function at a time and then looking to see if any fresh fluids had sprayed out. Nothing found. Wondering if there's some relief valve that momentarily opened due to an overload and dumped about a quart of fluid?
