I'm trying to remove the HB from my LS-6. I twisted the hell out of the fine thread bolt on my $19.95 HB puller, and the damper did'nt move. I'm in the market for a remover/installer kit, any suggestions?
I have had this same problem myself. It surprised the guys at the parts store that I actually twisted that fine thread, hardened bolt. If you have an impact wrench, use it! I replaced my twisted tool with a new on and have not had any trouble since if I use the air tools. I guess the hammering action of the air wrench helps break a stuck damper loose.
I was using an impact! How should I proceed. I've taken a few of these off before, but never had this much trouble. The motor is an LS-6 crate engine (about 8 yrs. old, 2000mi on it) I should'nt be having this much trouble!

BB balancers are sometimes very tight. I've had several that were a real problem. You need a top-quality puller with a large diameter, fine thread center bolt. Helps if the parts are hardened. I've had apply a little warmth to a couple of these to get them moving.
Rat balancers are a pain! I took a ton of them off boat motors, most where very difficult to remove. I used a Snap-On puller and just as important the installer. Never found one that I could not get off, did find some after market ones that needed to be "fitted" before use.
Hey guys, I got the balancer off without any damage, and without purchasing a new puller! I actually had a 9/16 fine thread bolt to fit my puller in my bolt bin, of course it was only 1-1/2" long! Using sockets, washers and a few other things as spacers, I was able to impact the balancer all the way off. I am a mechanical engineer, and I just don't understand why you would need such a tight press fit! There is a keyway and a bolt on the end of the crank, I would imagine a lighter press fit and some sort of lock on the end of the bolt would suffice. I guess I'm just glad it's not a taper lock fit(like on an outboard motor flywheel) those are even scarier!
