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.

Brian,

Well done, and well documented!

I'll be doing this myself shortly... Might I ask where you got your crank pulley holder tool?

Thanks,

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.

Do your knuckles have any skin left on them?
Well done.
Is it really a DIY?

The tool was only $38 so it was well worth it.

BrianS

LOL, absolutely! I figured there HAS to be others out there that like to do their own work too. Might as well include some pics while I'm at it.

No, this is the older style pulley.

BrianS

3 hours!!?? That had to include lunch and few coffee breaks. Now you know why I DIY as much as possible. Crooks.

BrianS

There's a plenty of room once the fan is removed. No knuckle busting or blood letting at all, unlike the small donation I left with the header install.

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

awesome write up! That crank holder tool definitely saves some time

Nice write-up with pictures

Hows the VRP pulley wrap kit?

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!!!!!!!!

I like factory tools for certain tasks, but they tend to be expensive. For the crank holder tool, you figure it's not one that's going to get used often, so it's not necessary to spring for the MB factory tool (unless you're in the business of doing pulleys). Baum Tools offers an equivalent tool for about $125, and at the lower price end is the one linked to in the post above and one offered by ZDMak tools for around $40 (probably same supplier as the other inexpensive one - from China with leaded paint on it ).

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.

Thanks Brian,

I definately think I can handle that!

Best,

RoydRage

BrianS

Thanks. The wrap kit is holding up great and I had enough slack in the belt to accomodate the larger 168mm pulley. If the pulley was larger then I would have needed a longer belt.

BrianS

Damn, now I gotta go change my shorts! So you may a few spare sockets laying around...

RoydRage

Just A FEW!

LOL!

good lord, your tools are probably worth 4Xs as much as my car!

Brian, good job there buddy! Glad you like your pulley and software.


OT: Hey Tony, show em your welder.

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.

Hoses from the FAN ?? I have to go out to the garage and check this one out.

waxking1

I think they are just clamped to the back of the fan but I can't see how to get them loose.

It turned out that one of the fasteners was missing on mine which happened to be the small (10mm I think) one at the bottom of the fan shroud. That particular bolt held the coolant pipe in place at the bottom. The other nut is is located directly in front of the power steering pump pulley. Push the hoses aside and you'll be able to access it no problem. Box end wrench or a smaller 1/4" drive ratchet will work. Then pull the coolant pipes out of the plastic mount. Look at it for a minute and it should be pretty clear.

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.
