Default 782/KT17 Series I oil leak

This is my first post on the forum. Last year about this time I was lucky enough to be given a 1980 vintage 782 in good condition. It has the original engine and a 50C mower deck. It had been stored and mostly neglected for the last 5-10 years. I managed to bring it back to life without too much work -- fuel system, electrical, fluids, belts, etc. No major repairs needed. I have been mowing 1-1.5 acres weekly since spring and it starts and runs like a champ.

In the past month though it has suddenly developed what seems to be a pretty big oil leak. It went from not losing a drop of oil to needing a ~1/2 quart a week. There is oil everywhere. Searching and reading back through the forum it looks like my likely culprit is the front crank seal behind the flywheel. The oils is all over inside the cooling shrouds around the heads and coming out of all the seams. I would guess this is from the flywheel and fan slinging the oil when it is running.

I have not attempted this level of disassembly and repair before and am worried about what I am getting into. Is there anything else I should be looking at? Is this common for this kind of leak to develop this rapidly? Is there anything else I should be looking to repair/replace/maintain once I have the engine out of the tractor?

Thanks for the help, Mike
