OK, had some more time here at work and so I downloaded the video and watched it again.

I think I see where the confusion is, and where my instructions could be considered backwards.

There are two marks on the crankshaft, one is the green "reference mark" on the outside of the crankshaft pulley, and the other is the half-circle notch referred to as the "timing mark" in the video. Its actually really hard to tell in the video because it is compressed and very hard to make out those fine details.

Anyway, I guess in my instructions the reference mark and the timing mark are backwards. I suppose this would not be the case had I turned the crankshaft one more full revolution.

Now, the reason why this worked obviously, is because both of those marks are just reference marks for the timing and the new belt installation. Apparently, so long as the camshaft marks are lined up, changing the belt whether at TDC or 180 degrees from TDC doesn't matter, so long as you install the new belt properly and you don't turn the crankshaft.

So, I can now say that I understand the discrepency, and I can update my instructions accordingly.

Now, to the OP, I hope that you did NOT turn your crankshaft pulley once you had the old belt off. If you did that, then you are 180 degrees off most likely. The other problem could be you are just a tooth off.

Anyway, I think my doing it backwards was simply a result of the video and diagram not clarifying between the two different marks well enough.
