HELP!! I'm losing my religion on this one. I have a samll gear 
box out of my irrigation traveler that needs a bearing replaced.

I need to figure out how to remove an oil seal (part 6) on the 
end of each shaft to get at snap rings (part 5 and part 2) 
behind it. I haven't got anything out yet, but the oil seal 
looks like it was tapped in place on original assembly - I've 
got nothing to hook on to to pull it out. Destroying it is OK, 
but how?
