Ummmm, I have no idea who you are, or what mine you worked at. As you no doubt know, Fording is no longer, so it's pretty doubtful that anyone in the Teck family would have even the slightest clue who Steve from Alberta is. I certainly haven't been checking up on you, and I think you need to spend a little less time reading things into peoples comments, that simply aren't there.
That being said, I work for Syncrude.
I also don't think that total machine hours are meaningless as has been suggested. In fact, I think Nige has covered the reasons very well, so I won't bother going there. But the fact remains, we had D11Rs running with upwards of 90,000 hours on them as total machine hours, and they were still worth rebuilding. In fact, they have all been cycled through Red Deer and rebuilt by Finning. The 475 I mentioned, had 25,000 total hours, and SMS couldn't guarantee they could get it to run right, even if they performed a full rebuild on it. That has to say something.
