LS Crank Balancer Install

[Code510]

Hey Everyone,

I'm in the middle of finishing up working on my buddies LS motor. I got the harmonic balancer/crank pulley off to replace the timing chain tensioner and the gaskets.

Regarding the installation....can I just use the bolt to press it back on? I see guys are selling all-thread with a nut and washers on ebay to install these. My concern is if the original bolt will snap inside the crank while trying to press the pulley back on.

Any suggestions?

Thanks for the help! PS, I did buy a new bolt to finish the installation.
