broken aftermarket alternator pulley - what belt to use now??

[Mike Corn]

Hello. I recently had been using my stock serpentine belt with the following pulleys.

- ASP Undercrank

- Water pump

- alternator





My alternator died, and the lack of impact wrench made me try to remove the aftermarket alternator pulley. However i stripped the hello out of it. The one on the new alternator seems bigger.



What kind of belt do I use now? Can i still use the same (stock) serpentine belt?

If the new pulley is the same diameter as the OEM and all other parts on that belt line are OEM, then yes.

 

[Mike Corn]

well no. I have and will continue to have the ASP undercrank and the water pump pulley. The diameter of the OEM pulley on the new alternator looks bigger to me that the aftermarket one I bought from Zabtek.

Get a piece string and measure the belt path and then buy two or three likely belts and return the ones that don't fit.

Thanks. So I have two right now. Stock and K060860. If one of them fits am I good to go?

Long as the belt is between the tensioner marks. Last two belt part numbers designate length. (0608XX)

thanks swshawaii. Not sure i understand what that means. I did manage to get my stock belt back on. It was very tight and I used a 3/8 ratchet to pull down the tension pulley, so maybe thats why it seemed harder than usual to put on.

The belt length indicator is a gauge, typically to indicate when the belt has stretched to the point where slipping or breakage may occur and, to a lesser extent, tension range (but I doubt its accurate toward that end). The belt length indicator should fall between the two marks.



Too short and there may be premature belt and or bearing wear; too long and the aforementioned slipping or breakage.



In the case of non-OEM pulley and belt sizes, it may not be accurate.

100% true, thanks. Tensioner marks using under drive pulleys would NOT be accurate. For those using STOCK pulleys, see picture #7 in linked project for wear indicator marks.

Without the ASP alt pulley. You may get a low charge rate @ idle.
