Can I shim the harmonic balancer

If you can make a accurate shim that has the proper bore diameter and with both sides parallel then it'll be fine.. If your shim doesn't make full contact with both the crank gear and the balancer I wouldn't do it...

I ordered a set of arbor shims. Though I don't know specifics, the pack came with multiple widths and are used specifically for shimming. My only issue is the inside diameter is 1-1/2" The snout has a ever so slightly larger diameter so will require opening up ID slightly.
