Default Crank Pully??

Anyone change one of these? It looks like mine has a very slight wobble...I don't know how much but it looks like ever so slightly....

Does this mean it will fall off???

Yes, and possibly..

I replaced mine w/ an underdrive ASP, used it as an excuse to do a cam upgrade.

Most stock pullies have a slight wooble, and as long as you keep an eye on it, it may last a while..

Or you could do what I did, and swap it, sleep soundly at night.

Did you do the swap yourself? What was involved? Looks tight between the rack and the pulley itself...also- did you notice any voltage issues going to an underdrive pulley?

Thanks!

No one wrenches on my car but me..

Yes, it's quite a job.. You must remove the radiator, steering rack, etc. to gain access. And if you do items like changing the crank seal (that is mated to the crank pulley, so you really should do it; this requires removing the water pump, alternator, etc.).

So now your knee-deep, 3/4 of the way into a cam install. If you ever want to do a cam, then absolutely do it while you are swapping the pulley.

No low voltage issues what-so-ever.

For just a pulley, do you think you need to pull the radiator? Not sure if you can get the puller on with it there, but as stated, it is not a trivial job. Its not hard though. I made my own press for re-installation and pinned the crank while it was apart.

Are there any VIN# that are affected?

I have a 2005 MN6 Z51
