I've got a new to me Komatsu PC75uu-2, and after it's been running a while and is up to operating temperature, it'll smoke black and bog down when under load. On initial startup, it has a little blue smoke for a minute or two, then runs real great for 15 or so, nice and strong, but when the temp gets up, i always get the same black smoke when i'm taking a bucket full. I'm waiting on my local parts place to get a whole round of filters in, fuel, oil, hyd, fuel/water seperator, air, but for now it's just the way it came off the truck.
