Optimized Proform 66514 Harmonic Balancer Review

Works great. Make sure you lubricate the threads going into the crank and the threads on the mainshaft. Makes the product easier to use and easier to remove from the handle.

Worked great for pulling the balancer. Balancer cannot be reinstalled due to missing components. I didn't realize they were missing when I first used it and unfortunately I've now gone through the 30 day return period to apply.

This tool took you a few minutes to figure out how to use properly if you've never used it like me. But once you get it right, it will pull out the harmonic balancer with ease.
