DIY Pulley Install
I just got my pulley today and couldn't wait to install it so I knocked it out tonight. It took all of about 45min total.
I got my ECU back from Adam on Monday which really woke the car up he sent me a 168mm Renntech pulley as well. Can't wait for full testing tomorrow.
Here 'ya go....
Remove the radiator fan in order to access the dampener's center bolt.
Grab your trusty crank pulley tool to hold the pulley in place while you loosen the center bolt.
Remove center bolt and crank pulley. Stock one on the left, Renntech on the right.
Close up shot of the pulley.
Another comparison of the two.
Install new pulley, new center bolt (torque to 148ft.lbs.+90deg.), make sure both belts are back on properly, install radiator fan, engine cover and you're done.
I was able to access everything from above so the car never needed to go up on ramps which made the install very straightforward.

Good work Brian. 45 minutes! And thanks for the pics.
The MB book says 3 hours for the pulley alone and the tech that did mine took nearly 1.5 hours. Of course, the shop wanted to be paid on 3 hrs.

If you have the crank tool, a breaker bar, 27mm socket, and a good torque wrench then yes, definitely a DIY project.

Nice job Brian!!! You weren't kidding when you told me you wrenched on your own car.. I figured, ok, you would do the TB but, I didnt think you'd do the crank pulley.. Good for you!!! 
BTW, do you know how much I paid for that damn crank pulley tool from MB???? $376!!!!!!!!

).A case where it didn't pay to go cheap was the calibrated oil dipstick. The aftermarket one was inexpensive, but didn't really fit correctly down the dipstick tube. I ended up getting the factory tool and using it to confirm the fill level after oil changes - more accurate than the onboard display and of course fit with no problems.

I'm working on changing a pully. This is not as easy as it sounds, at least not for me. I'm having trouble getting the hoses loose from the back of the fan. It is very tight behind the fan and I don't see how you could do everything from above, but I've never seen it done. I'm working from above and below and can't see how to get them loose, especially on the drivers side. Any suggestions? I guess I could put it back together and take it to a shop. My dealer is not mod friendly.

Check out the attachment which might help out a bit more. Sorry if I wasn't clear but you should be good to go now.
