This is my second replacement, totaling 3 new balancers. The problem was the broken keyway and old 8.8 bolt. Hopefully I have it torqued down enough! I also learned that you CANNOT reuse a balancer. Once removed the grooved surface is designed to distort as its pressed onto the shaft. You...

OK, I installed a new harmonic balancer and OEM bolt on Saturday. As expected, the new balancer was TIGHT, TIGHT, TIGHT. Even with an installer, you have to strong arm it so there's no way the crank is narrowed down. I also followed instructions on the TSB for the install - they said to...

Also, that area of "roughness" inside consists of small lateral lines designed to collapse and grip as the installer pushes the balancer on the shaft. That reduces the internal diameter a bit. With that, I can totally see why they say you can't re-use a balancer.

I measured from the end of the tape measure as well as from the 2 so you can get an accurate read. Not sure if a tape measure is accurate enough for your needs though.

I will tonight!

The welding and glue have nothing to do with the balancer. I got the trademark broken keyway (also all over internet) so I'm looking at options to fix it either permanently or at least until I get a new engine. The steel paste didn't work, nor did the welding of the balancer to the crank, but...

You are 100% correct. That's why that key is strictly for alignment. No way on this earth will a little key or a 1/4" groove hold that kind of force. It's all in the bolt. After the keyway gets rewelded, I am installing a new OEM damper (again). I just purchased a right angle impact...

Hold on guys, lemme catch up. Ok, the keyway broke due to the old stripped out crank bolt that was in the truck when I got it. It was the softer bolt, which was actually recalled on the civilian 6.2s and replaced with the updated bolt for this same reason. The balancer isn't spinning freely...

The duramax has a ton of flywheel locks on the market, but I don't see how to safely lock this flywheel. The shroud next to to the starter doesn't seem sturdy if I remember correctly (just a metal plate) and I'm not comfortable with sticking a pry bar into only one tooth of the flywheel and...

So a got a healthy 8K miles out of my makeshift keyway fix, but again, it failed. The bolt keeps slipping out!! If the bolt would stay torqued, there would be no problem. I used Permatex Red and a stronger bolt as GM recommended (10.9). Now I am having the keyway welded then dremmeled out...
