Underdrive Pulley Step by Step Install??
ok guys i purchased a underdrive puley for my z28..i have done the search method and found alot of info on installing the crank pulley but i couldnt find a step by step...and i also saw a few people had mentioned that you needed to use a new crankshaft bolt to hold the pulley on since the stocker is good for one hold...can anyone clarify this?? and where can i get them...is there anything else neccessary besides the pulley puller....and is 200ft lbs of torque good for reseating it..im really looking for a step by step...thanx in advance

Um, when I installed my pulley it was easy and it came with 3 new longer bolts.
Before you even begin, make sure to leave the car in gear and set the parking brake.
1. Remove the Serpentine Belt. You should have a new belt that is either 59 1/2" or 60" long.
2. Loosen the 3 bolts that hold the stock balancer on. I did this with a 12" rachet.
3. Once you have the 3 bolts out, you SHOULD just be able to coax the balancer off by giving it a couple light taps with a small hammer and wiggling it. Before you pull it off, make a note of where the little arrow is pointing because you need to re-install it the same way.
4. Install your new pulley behind the balancer and make sure to line up the arrows on the pulleys.
5. I started the new bolts a few turns to keep the pulley and balancer lined up when I re-installed them. I just lightly tapped on it with a small hammer until it was back flat up against the hub and then tightened each of the 3 bolts to 65ft/lbs.
6. Install new belt.
7. Done. Start car, watch voltage gauge sit in the yellow area at idle..
