I was installing my banzai aluminum pulley set, as my OEM set looks thrashed. I'm stumped on the Underdrive pulley as I've read that I can mess something up. Is it one of those easy in and out installs, or is there more to it. I was also curious as to how you guys got it to stop rotating. I don't have the means to pull the engine out, and it's currently not running as my UIM and TB are getting plated. Thanks!

 

I usually hold it by hand but you can also use a strap wrench or a small impact to loosen the bolts.

 

How swole are you ? Bought a nylon strap wrench, it keeps slipping. Is it an easy off and on installation. As in I wont mess up the eccentric shaft?

 

Sounds like you are trying to remove the 19mm e-shaft bolt. Just remove the four 10mm bolts that hold the pulley on, these are not difficult to remove and there is no way to damage the e-shaft or bearings since the hub is never removed.

 

I'll do that today, didn't realize that, the 4 bolts only needed to be removed.
