Look! Does this Powerbond pulley look fully Seated!? PICS Well I just took this thing out of the oven and cranked it down using hawk's tool.
ls1howto says to crank it down till it seems impossible to turn. Well I am at that point. I checked the alignment of the underdrive pulley with the other pullies with a string and it seems to be dead on.
Does that gap look ok? Even if I could crank it on anymore then the pullies would be out of allignment. I was worried about the round oil seal leaking due to that gap?
What do you guys think!?

Haven't had a chance to torque the bolt yet. I just used hawk's tool to push the pulley on this far as shown above.
ls1howto says to torque between 200 - 240ft/lbs with old bolt then torque new crank bolt to 37ft/lbs then turn approx. 100 degrees to stretch bolt into place
Well my 1/2" torque wrench only goes to 150ft/lbs.
I haven't gotten that far because I was hoping to figure out a way to hold on to that powerbond pulley without dropping the starter being it's an A4
I read one guy just wrapped a chain around the pulley and sway bar and it held that way But I don't know about that...

If someone has the hub length of the Powerbond, you can figure it out from the depth requirement on the stock pulley hub and the difference in lengths between stock and Powerbond. That's what I had to do with my ATI. See below for stock pulley measurement.

What you're seeing is not what you think you're seeing. You're looking at a step. The step below the one you're looking at is the one that goes through the timing cover seal. That's the one that either prevents or allows oil to get by. Next time you remove the pulley take a closer look at it and you'll see this step.

For the record, even though you can probably get away with it most of the time you really shouldn't install these bolts with an impact. You can get it started sure but you need to torque it by hand to finish it. Reason being is that since it's a torque to yield bolt the impact will just start "bouncing" if you will off of the elasticity of the bolt once the bolt reaches a certain torque value. You'll never end up being even anywhere close to where the spec is.
