Underdrive Pulley ?s
Underdrive Pulley ?s Is there a reason why the ASP pulley set has a steel alternator pully? Could I whittle one out of aluminium or drill a few holes in the steel one, or it it heavy for a reason? Also, I searched around for the Craftsman pulley I need and didn't find it. Anyone remember the part number for it?

If you look up the ATI superchargers, the problem they are having is their idler pully is aluminum which leads to it wearing down VERY fast. People have actually started making steel ones.
Overall it is not very heavy. I have that same setup on my car. If you are really worried about the weight, you could probubly get away with drilling a few holes in it but don't go overboard.

Re: Underdrive Pulley ?s Where did you get it and much was it? My ASP set came with the steel pully <img border="0" title="" alt="[Frown]" src="gr_sad.gif" /> . Was it a extra cost thingie, a durability issue or was it just a case of ASP wanting to save mone? Hmmm?

You have to ask for an aluminum alternator pulley, part number 840084. The aluminum is the same price as steel. They make special pulleys of varied sizes and weights on order. Just tell them what you want.

Re: Underdrive Pulley ?s Thanks Larry, I drilled a few holes last night.
Still perturbed about not knowing I had to ask for the aluminum one. <img border="0" alt="[bang head]" title="" src="graemlins/gr_banghead.gif" />

You almost have to do this on a mill. You can destroy or prematurely wear out your alternator bearings if the pulley is out of balance.

Re: Underdrive Pulley ?s If it were me, I wouldnt even worry about it. The weight difference isnt going to make that much of a difference, nothing you will feel in the seat of your pants! I would agree with Larry on the drilling of the holes. <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> If you want an opinion, dont use the alternator pulley, it never affected my charging system whatsoever! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> Speaking of that, I dont know of anyone who is running the alternator pulley, theyve never show any kind of problems with the charging system. So just put on the stock atlternator pulley and you can be on your way! <img border="0" title="" alt="[Wink]" src="gr_images/icons/wink.gif" /> Thanks I hope that helps.
