Re: 74 LS4 Harmonic Damper Removal

Thank you to everyone who responded, I got the damper off this morning and very happy. Having never removed one, I was cautious. I did not want to break anything or get injured in the process. I intalled the grade 8 hardware, lubed the tip and the bolt; using a 1/2" ratchet I tightened the center bolt, and gave it a whack with the hammer. It was very tight, but I kept on turning and once I saw progress, my confidence went up and it got easier.
Here are a couple pictures, if anyone sees something wrong please let me know.

When you re-install the balancer make sure you do the following:

1) Make sure there are no "burrs" or "dents" in either the ID of the balancer bore or the OD of the crankshaft snout. There must be NO PLACE where the balancer bore or crankshaft snout are effectively increased by even a 0.0001";

2) Use a good balancer installer, the type with a REAL thrust bearing.

Todd, add to Joes install,I put a dab of RTV on the key way of the damper, This will help prevent oil from making its way down the keyway and getting slung onto the engine when running.
