Does anybody know the part # to the pulley behind the supercharger idler pulley the plastic one not the metal one.

 

Here's a pic

 

The part number is :1132020419. Those pulley's are sold as kit together. They are pretty expensive from the dealer.

Your better off contacting Shardul and he will sell you those two pulley's plus the tensioner pulley a lot cheaper than dealer .

 

Is that a tightener pulley #: "113 202 00 19"...??

ZAYED,,

 

Thanks got it

 

Just replaced my plastic pulley with the gates 38019 last week. Cost $20. All you need is a washer between the 2 pulleys to keep them from touching and correct the offset. The offset is about 1/16" different. Other than that, exactly the same and works perfectly.

 

Does gate make one for the rear accessory pulley you left plastic?

 

i think the plastic one is the Gates one. same as the oem.

but go for a set from Shardul, much better.

 

Can't be there completly different ribs..nothing against shardul hes great (i speak form expirience) but i can get them cheaper....with a little research

 

The gates one is the plastic one ( closest to the timing cover) and the ribs are exactly the same. Gates makes one that is the same spec as the aluminum one (blower belt) as well but it's steel and not aluminum. I've never personally used the gates replacement supercharger idler pulley though.
Gates 38019 = plastic pulley
Gates 38052 = metal pulley

Nothing against shardul, (very helpful member) but for $20 you can't go wrong.

 

Good find "stockC43",

what's the width & height dia of that OEM or gates pulley..??

ZAYED,,

 

I can't take the credit for it. I found a thread a while back about it and kept the part numbers. Figured they would come in handy one day. My recent e55 purchace had the cracked pulley and I figured I'd try it.

A link to the pulleys they offer
