I usualy put the front end up on jack stands put my breaker bar on it with it hanging down get my self under it and use my foot to break it lose. No pain there just some light force and then a quick hard push and it comes right off.

Also be advised that the cage is held on with a bolt up above and two down below... the one up above you get at from the hood......

I did not relize there was 3 when I took mine off and I thought I did some serious damage when trying to remove the stock pulley. I thought I may have bent my harmonic balancer... but it was several thousand miles ago and all is good.

 

I did basically the same as Suavy; put my L up on jackstands and got the longest piece of pipe I could put over my breaker bar to get as much leverage as I could to put on the pulley bolt. Laying underneath the truck, I didnt think for a while I'd ever break it loose - but all of sudden - it broke loose. So just be prepared for it to be tight - but it will come loose.

 

I think you'll be fine. Don't bang the heck out of things and nobody will know
