Had the unfortunate experience of a leaking crankshaft seal this month but wanted to recommend a tool I found a while back. The ATS crankshaft seal tool 5209 worked great on my Superior IO-360 crankshaft. This tool sells for $70 instead of the Lycoming version which sells for about $950.
As others have said on here most of the work is cleaning, prep, and getting the sealer (Dow 737) in right places and not in the wrong places. Stretching the seal with this tool was no big deal.
I bought mine at Skygeek but ATS also sells them direct.
