i have a 3.8 ecotec and i think on mine its 25mm or 26mm.i just used a socket and a breaker bar,then under the kframe one quick turn of key on and off to crack it. then 3 jaw pulley. http://autofix.com.au/blog/wp-content/uploads/2013/10/Puller-in-place.jpg like in this pic is how i did mine up to you tho how you go about it.

you need 3 1/4" x 2 1/2" unf bolts and washers to stop the bolts coming through the pulley

Also if you have a cheapie puller the centre bolt may not be long enough to reach deep enough to the crank. I use a round metal bar about 60mm long (without digging it out and measuring it right now) and a diameter a little smaller than the hole in the crankshaft. Some people will put a socket inside the crankshaft and that works fine too. Whatever you use just make sure it's not gonna get stuck in there when you start applying torque to it or you'll have another issue to solve.

Bunnings have the bolts you need. You'll find them easy to screw in without the puller but they can be a bit fidgety to line up once you're actually fitting the puller. Take your time and use care. You don't want to cross thread them. After you've done it once it gets easier.

Bunnings stocks bolts? It can't be true!

The pulley kit you purchased was it to suit a VX V6 or just a universal unit.
I bought a pulley kit just suited to the Commodore V6 which I'm yet to use and it includes five sets of three fixing bolts: 2 x1/4"UNF, 5/16"UNC, 3/8"UNC, 3/8"UNF and also includes installing adaptor sizes: 7/16", 1/2", 9/16", 5/8" & 3/4"UNF 12 x 1.5mm, 14 x 1.5mm & 16 x 2.0mm.

as i mentioned earlier
use the CORRECT puller when removing a harmonic balancer

if you are throwing the old balancer out it does not matter
but still good practice to learn to do things correctly

Thanks lout you are correct.to be honest i was doing it how someone else said to do it on here.so basically i could have saved $60 on the pulley and just used my steering wheel pulley i had in the draw the whole time.
