I am trying to install the pulley and it is taking a lot of hammering to get it to move I am not even to the front seal or to where I can use the bolt to pull it in. Is this normal with installation? I know it is tight but it pulled off pretty easily with a puller. The key seems pretty tight but it's the one I took out. Is the key suppose to be so tight that even tapping it a bit the key does not want to go in the slot? Any advice? Or is this all normal for the pulley on a 292

While those Y dampers are snug on the crankshaft snout, it shouldn’t be so tight that it doesn’t install reasonably easy with a moderate amount of tapping.  Rather than using a hammer, I use a damper installation tool and with that, the Y dampers slide on reasonably easy.  I will suggest pulling the damper back off and double checking that the woodruff key has not slipped in its slot on the crankshaft snout and also check both the crankshaft snout and damper hole for any damage that could be adversely tightening up the clearance.

Ray here is a picture of a tool I made to install the Y block damper.  It is basically a 5" X 9/16" grade 8 bolt that I threaded most of the way.  I use a grade 8 nut and a stack of washers as necessary.  I think others here have done the same and it works well.  I once read horror stories of the damage that can be done to the thrust bearing on the crank if the installing the damper involves too much hammering.  Good luck.
