Default 7A vs NG crank pulley

Anyone seen both and know if they're different?

The TB cog/gear on the back is the only difference

Default different tooth count/diameter?

Do I essentially just replace my AAN serpentine belt pulley with the NG Vbelt pulley... keeping the AAN TB gear on the back?

Default Wait, what exactly are you doing?

The TB gear has the same # of teath and diameter, but the offset from front of the block is different. By using an NG gear on with a 7A head, the timing belt will hang off the back of the cam gear about 1/8"

Default ohh... no... AAN swap... converting to v-belt... I have plenty of NG parts, but no 7A

I was under the impression I needed a 7A TB gear(crank) and v-belt pulley to convert the AAN to v-belt... and someone told me the 7A and NG crank pulleys were the same.

make sense?

Default Actually I take back what I said,

The TB gear is the same, it's the damper that has a different offset. It will work, just with a slightly misaligned TB. I went through this a few months back. You can turn down the NG damper to make it work.<ul><li><a href="http://www.motorgeek.com/phpBB2/viewtopic.php?t=14770&amp;postdays=0&amp;postorder =asc">http://www.motorgeek.com/phpBB2/viewtopic.php?t=14770&amp;postdays=0&amp;postorder =asc</a</li></ul>
