time it takes to install underdrive pulley?

[ULTRA Z]

Yea from all the work i have done from starting off to now its always been about the right tool or trick you learned after you done half a dozen of them lol

[BloKKem]

I can pull and install with rad and fans installed. Just have to pull the belts and starter. Torque from underneath the car while holding the flywheel. Use 3 jaw puller to get balancer off, and use a piece of all thread and nut to install the UDP before installing balancer bolt and torqueing down.

Real simple and plenty of room.

I gotta tell you though, holding the flywheel to take that crank bolt out is easier said than done. At least for mine it was. The first time that crank bolt was removed from the factory install, I swore I must have gotten the "extra torque special" because no amount of technique on holding that fly wheel in place was good enough to counter the rotation based on the amount of torque required to pop that bolt loose.

...unlesssssss of course you happen to have that GM spec'ed tool that's designed specifically to fit in that hole and hold multiple fly wheel teeth.

what is the reason for the longer bolt? Why can't you just use a new bolt, like the ARP, torque it down, and call it a day?

The longer bolt is to press the balancer on. Another trick is to heat the inside hub of the balancer and it will slide all the way on like butter.
