The hub of the damper should bottom against the timing gear and oil slinger located inside the timing case cover. If both those objects are present and installed correctly the damper will be at the proper depth and can't slide back any so the bolt can torque down. The more important in/out distance to consider is the fan and generator belt groove alignment rather than the indicator mark relationship.

The photo shows it is seated all the way. It seats at the back, inside the timing cover. Just for reference for other folks who may stumble across this thread in the future, the PS pulley is merely wedged into the balancer and can easily be pried out. If you are going for a painfully correct show restoration, the balancer should be engine color and the PS pulley black.

One other thing to consider: the damper hub is press-fit on the crank snout. Engines like Chevy do this too. The bolt torque is significant (160lb-ft?) which is what is used on Pontiacs too, but their hub/snout is slip fit. This is a belt & suspenders approach typical of Packard, but only one (press or torque) is necessary.

When pulling down the harmonic balancer, it's better to have the PS/AC pulleys off and out of the way. Once it's bottomed, then install the accessory pulleys and do the final torque down.
If one is concerned about the timing mark visibility, just cut it full width on the damper with a three-cornered file. Then paint it with white paint. jack vines

Thanks for the feedback. I did try to pry the PS pulley off but it wouldn't budge and I felt I was going to distort it so stopped. Maybe I should have tried harder as it would have made all of this so much easier. Next time..
I put the water pump and pulley on to check alignment with the damper and it looks like it all lines up just right. Before I put the damper on, i poked around in the recess of the timing cover. There was a spacer/bushing around the crank that was loose. I could tap it with a screwdriver and it would wobble. I assumed that it was group 5.04095 from Parts plate No. 28 and that the damper shaft would press against it when in place. Does that sound right? thanks again to all for your quick responses. -Bob p.s. my apologies to the purists for my black damper. It was a lot easier to use a Hirsch Chassis spray paint, then brush paint the ivory engine enamel...

If timing chain cover was removed for any reason then besure to loosen the timing cover bolts to allow the seal to cenntralize on the snout of the damper.
