Alternator Pulley Shims
Hi just replacing my belts and need some additional shims as i dont have enough/the right combination for the new belt (want to stop the burning!!)
Now the OPC has some available at £3/$6 each!! Is there an alternative to official porsche shims as these look like any other washer, just thinner!

?? If your belt is burning, GENERALLY, this is because your belt is slipping! If this is the case, you should be removing the shims between the pulley halves so as to tighten the belt.

You should always have the correct number of shims. They just get moved inside and outside the pulley halves to change the adjustment.
There should be 3 each of:
964.106.517.01 shim
964.106.268.00 shim
I think I paid $3 each from Sunset. No affiliation.

In total I have 4 of the shims that go at the back nearest the fan (with 3 holes) and 4 of the plain shims, along with the 2 half pulleys
I read on here that there were more than that and assumed that some had gone missing over the years.
With more shims on the belt is very loose......what should the correct number of shims be for the outer belt (one nearest the bumper, not the AC belt). I am assuming that i do not have the correct combination to get the correct spacing....
Thanks

If your burning through belts check that you have not accidentally locked the fan pulley to the alternator pulley. I went through three belts before I figured this out!!!
If you still need shims I have a few spare you can have.

I thought (maybe incorrectly) that the belt was getting hot/smoking because it was too tight....

As a guide, I found that when I put new belts on that two shims between each pulley gave the right tension. It's also important to ensure the pulley halves mate together evenly by tightening the three nuts that pull them together a little bit at a time and continually feeding the belt round the pulley to prevent it jamming.

I took some pictures when removing everything and placed all the spacers, pulleys etc in the correct order for refitting so I am pretty sure I have in the correct place. Its just that I am worried if I have them too tight I will damage the alt bearings!!
I looked at a friends belt setup on Monday and they seem a lot looser than mine at the moment - deflecting about a quarter inch.
How do you check that you have/nt ocked the fan pulley to the alt pulley?

Ok, so i have had another go at this tonight.
Looking at the new belt it says 10 x 775, the original belt states 9.5 x 776.
Does the width make a big difference as to why I cant get the belt tensioned right without it smoking and getting the pulley hot!
Getting a little frustrated with this job now as this is supposed to be the easy part....

To check to see if you have locked them together simply grab hold of one of them and spin the other, if the other seems attached to it then it probably is. Like I said, I did this on mine and cooked the pulley so much I went through 3 belts and now need a new bearing, DOH!!!
