396 Harmonic Balancer Install Question

I am putting my 396 back together after the cam install. I purchased a new stock balancer and a balancer install tool. I installed it last night, but I want to make sure it is on all the way. I am using another timing cover because my other one did not have a timing indicator on it. This one has "40 69" stamped on it. I am a little concerned that the balancer was not on all the way. The front of the balancer did not end flush with the crank snout, but after looking at the "original" balancer, it also has wear that stops short the same distance as the current balancer. The timing indicator is not over the balancer. And, the back looks like there is a lot of space between the balancer and the timing cover. I did mock up the water pump and pulley and the water pump pulley and the balancer pulley line up dead-nuts. I think I'm good but wanted some feedback. Hope this is not another "1965/66 Block only" difference.
Thanks,
Brett.....

Re: 396 Harmonic Balancer Install Question

I don't have experience with that engine but I just did this on my 327. I took measurements before I pulled off the old original balancer and there is a full 1" recess from the front face of the balancer to the nose of the crank snout. I also measured the crank snout and the old and new balancer and it verified that there is a 1" recess when the balancer is full seated against the crank gear. Like yours, there was also a visible mark on the old balancer, but on mine at 1" where it had sat for 50 years. When I put the new one on with the installer tool, it was very clear that it stopped and could go no further. When I measured the new recess, it was exactly 1". All the pulleys line up.

All this is to say that I think you're good to go if the old recess matches the new, you could go no further when you installed it, and the pulleys line up. Make sure you verify TDC on your new balancer.

Re: 396 Harmonic Balancer Install Question

You are good! The crank has a step machined on the stop. When you pull the damper up to the end of the snout it hits the stop. The increased resistance of trying to drive it on any further will result in a sheared installer bolt if you keep going.

The BBC and all high performance SBC made before 1968 have a retaining bolt and washer to keep the balancer from walking back off again.
