How to replace output seal on Woods BB60?

[wirlybird]

Looking around for any info on replacing the output shaft seal on a Woods BB60.
I'm finding general info on replacing the seal but nothing specific to the BB.
Would kind of like to see what I have before just digging in there and damaging something!

Thanks.

Well now that I've gotten into it a bit more it's pretty straight forward. Snap ring hidden deep in a groove and is about impossible to get out!
Metal shield is next and doesn't want to move!
So far though gaining on it!
