What sort of puller were you using to try to pull it off? If you were trying to remove it the wrong way that would explain why the tool broke first.

Your really going to need either the actual GM J tool kit (LT1 Hub Remover/Installer) OR something equivalent (Hub remover installer kit) sold by say Snap-On or another tool distributor. Its a specific type of puller that uses a strong bolt threaded into the crank to "push" and "pull" the crank hub/balancer. Most other tools will break.

I have heard of people making their own kit using stage 8 bolts and stuff from hardware stores to make a puller, but others would have to post about that.

That is correct! The LT-1 crank hub DOES NOT have the large diameter center hole that most SBCs have, so you can't slide the center insert in to it. If you try to use a regular puller, all you do is pull against the center of the crank hub, not the crankshaft, and lock the whole mess up.

Yup, I learned that after breaking two pullers. I finnaly got smart and looked inside towards the hub bolt and saw I was just pulling/ pushing the balancer/ pulley against itself. My haynes manual said to put a deep socket on the hub bolt so the puller can push on it. To the OP, is there any way to get the broken piece out? What broke off the threaded rod thed goes into the hub?

that's why you use a longer grade 8 bolt inside the hub for the puller to push against. typically use a 4" bolt.

Just a "heads-up".....In case you weren't planning to replace the oil seal in the front cover, you better do it now, since the "torch job" probably cooked it really well..........

For anyone else reading this thread, I just want to point out that this is the worst way possible to remove the damper hub.

Keep in mind, the LT-1's balancer is a 2 piece affair. Therefore, if the "arsonist" took the outer ring off first, there was no rubber to get damaged by the torch, other than the oil seal in the front cover.
