Haven't done one yet, but did look into it sometime ago. Pretty straight forward, the seal housing has pry tabs on it, so you can pry it out. When installing tap evenly around the edge, make sure you lube up the inner portion that mates to the crank, so it will slide on easier. This pic may help

a tool like this http://www.myaston.com/k/?view=item&...taller+J+35621

makes the job VERY easy. I did not use the KM one, IIRC it was a "matco" one i borrowed from a friend but works the same. bolts to back of crank and you just screw in the center bolt/handle on tool to press it in.

As mike said you can tap it in evenly without a tool but if you can find a tool cheap/free than use it.

Grease inner lip of seal before install. My $02 is go with the 'rubber" FelPro (not teflon) rear main seal.

BALLS,....Thanks again for the info on this. In a few weeks I'll be installing my YANK and will change the rear main at the same time.

I used the felpro rubber one as well. So far no leaks. As Roger said, use the tool if you can borrow one. If not, I used a small piece of wood to tap mine in. It is only a 3 minute job --- once you get the tranny out!

wow 80 bucks is not a bad investment, but its also not in the budget right now, unless there is a great sell out here, i think i missed the 4th sale
