Couple quick questions
I'm going to have a number of dumbass questions over the next 90 days so bear with me. Trying to get the bottom end assembled this weekend so......
1 - I ordered my new rear main and it also came with a little o-ring that's about 3/4 an inch. What the hell does that go to?
2 - anything special I need to know about installing the rear main? Not much online about installing a 1 piece rear. It appears it is just held in via the rear cap?
3 - should I use permatex on the corners of the rear main cap? The book I'm following is for a gen IV unfortunately so I just wanted to make sure
Thanks guys, have some patience with me here. Plenty more amateur engine building questions to come, but trying to get the bottom end together so I can get bob some measurements next week

I've seen some people say they just point the new one in with the old one and a blunt punch. Reasonable approach or not?
Does autozone or advance rent one of these tools?

They do make a special tool to install the seal. Some say you must use the tool. I use my brain a block of wood and a hammer. Never had an issue. If I purchased special tools for all the different seals I've installed over the years I'd need another toolbox to put them in and id never be able to afford a boat.

10-4. So bottom line, do final crank install then pound in seal. I assume a thin coat of 30w oil on the cra shaft seal side is appropriate?

I usually put a thin coat of rtv(on outside of seal) for insurance and help it slide in too, it should push in pretty easy,but they prob dont recommend it
