Title: Aircooled Alternator
Post by: drwheetos on February 04, 2011, 05:51:31 PM

Hello!

Does anyone know the nut and thread size for the nut that holds the drive pulley onto an air cooled alternator??

Thanks in advance!

Mark

Nice one, thanks.

Does anyone have a picture of how this assembly fits together?

Hi, While you're there! Someone has told me to tighten the belt I need to remove the 3 nuts and loosen in order to remove shims from within? does that sound about right? I might have a go at the weekend.

Cheers!

The pully comes in two halves and the belt tension is adjusted by removing/replacing the shims. To tighten the belt you will have to remove shims (put the ones you take off on the outside as you may need them next time). There is no science to this job, it's just suck it and see. Do it slowly one shim at a time until you have got it right. The shims come in a couple of differnt sizes so take out a small one first and try it. If that's not enough put the small one back and take out a thicker one. And so on.

Let the car run for a while to make sure the belt won't pop off. If it does, the engine overheats smells really bad bad news. (not that I would do that of course :oops:)

Lovely, thank you for your advice! I'll have a go soon - just that I cleaned the little lady sunday and she has since refused to start >:( (i washed but not polished) I'm getting a spare spark plug tomorrow to check for a spark (fuel pump working ok) Tried tow starting :(. I think Alan the Audi (mine) may be jealous and having a tinker at night!
