250 I6 Harmonic Balancer Installation

I posted a similar question a while back, and got some answers, but I don’t think i knew enough to, now that I have removed the harmonic balancer, I do. The problem with reinstalling the harmonic balancer is that i can’t use a threaded installation tool because there the end of the crankshaft is not threaded. So the standard installation tool will not work for me. I’ve read a few ways, pounding it on, which i know will probably cause damage, then there’s soaking it in hot oil or water for it to expand, and lastly, drilling and threading the end of the crankshaft. Any advice?

Straight shot,block of wood,3lb hammer,works very well.
