2010+ 6MT Underdrive Pulley Pic Request

Can anyone verify what the pulleys look like for 2010 and up 6MT? I know there was a change in 2010, so I wanna do some verification. Installed pics would be nice as well.


Thanks,

Matt

There are two different configurations:

SOP-5/08 6MT only
6/08+ 6MT & all DCT

Belt routing:

2008-5/08 6SPD models (non DCT) belt routing


6/08+ and all DCT belt routing


Crank pulley is the same for both variations. Power steering pulley, belt routing and length is slightly different in 6/08+ 6MT and DCT.

When I looked at my power steering pulley, it sppears that besides the 3 bolt holes there is a pin that goes through a 4th hole which I don't see on the second pic you posted.

I believe you mentioned you have a MY12 when you dropped by? It you look closely at the 2nd pic, there's a alignment pin at about 1 o'clock on the P/S pulley.

The configuration hasn't changed since mid 08. 5/08+ M3s now use the same configuration, DCT or 6MT.

It is harder to see in the pic. Correct, mine is a 2012 as I mentioned when I saw you. Mine has a silver pin which led me to believe it was something different than the ones in the pics which appear to be black as far as I can tell. If you say that they are the same though, I will go with it. Can you verify the part numbers on the MS pulleys so I can tell if I have the correct ones?

Part number should be 10.00.012 on the P/S pulley.

So I checked what I have and it indeed has the same part number as mentioned above. Is there supposed to be the alignment pin on the MS one? If so, it is not there.

Yo Brother, Seriously, it's really easy to just draw a diagram after you take the air box and fan out. Draw 2 diagrams: One for the inner belt; one for the outer. No problem!

p.s. I like the way you're digging into this now. My previous thread got you fired up!!

Not worried about the routing at all, just wanna make sure the pulley I have is correct before I waste time.

Yeah, it's one of the last mods I have sitting here waiting to install from before I got the car.

It's not utilized during installation, the pulley is installed without it.

I was just looking at the aftermarket pulleys on some vendors websites and it looks like the Active Autowerke pulley kit comes with just 1 pulley(crank pulley) while the Macht Schnell pulley comes with 2 pulleys(crank, and power steering pulley)? Is that correct? Wonder why they one has the ps and the other doesn't?

This is correct. I don't however know the reason why one has one and the other has two. I'm guessing they achieve the same things.

Print the pic and trace the belts with a red marker. That worked for me.

Belt routing was the least of my worries.

M/S and Rogue pulleys replace the double sided ribbed power steering belt with an off the shelf single ribbed belt. As a result they need to replace the ribbed power steering pulley with a flat one. AA uses a custom made double sided ribbed belt that is the same as the OEM design just in a different length because of the smaller crank pulley. AA feels the single sided belt design is a poor solution and can lead to power steering issues (slippage, etc.). Others have used the M/S and Rogue design with zero issues. Drawback to the AA pulley is if you shred their belt you can only get the correct replacement through AA. The M/S or Rogue you can go to your local auto parts store.

From their website:

"Macht Schnell Performance Underdrive Pulleys have no negative effect on accessory operation and come fully equipped with new belts".

You should have received 2 belts, it seems the forum member you purchased them from did not include everything.

You have a PM with the belt part numbers.
