DB alterator w/ pulley - belt alignment issues

[lively]

ok so i bought and installed a db alternator 105 amp , but now the belt is sitting to proud outward , i looked at the pulleys old vs new and they are defiantly different sizes the new one has a smaller pulley
and the old one has a larger pulley , can i swap these out to align it better or those of you that did the upgrade did you have to shim the other pulleys ?

thAnk you !

With an impact gun you can swap pulleys. Keep an eye out on your volt meter. I had two of those go bad in a years time. Just bought a new one from Napa because they wouldn't warranty it for the third time a few days after the one year warranty.

Nope. I swamped the new one I got from Napa. Just hold the fan with one hand and impact the nut off. Pretty easy
