Ok, 1-1/16 fit snug.. I have an auto and I see the question all the time how to break loose how to tighten.. I used my starter to break loose, and I vise griped the harmonic balancer and let it rest on something metal... Worked great. It was just loose.. thanks for the replies
I saw somebody try that trick on a VG engine and they ended up breaking the starter housing. If you don't have access to an air impact gun, the best and safest way is probably to use a small tie down strap and run it from the frame, around the balancer a few times and back to the frame. Then use a breaker bar and socket on the bolt.
I suspected mine to be loose anyways bc I know the guy that had it before me do the timing set and he didn't use a torque wrench just bumped it with impact. I should've said there's that risk if you do it that way you're right.. I didn't have access to a strap at the time.. could've used vise grip both ways I believe, it really held.. just make sure the vise grips aren't slipping on the pulley and damaging it. I put out feet on tire with both hands putting out and the vise grips didn't slip.
