[AT] Rear main seals

[Cecil Bearden]

I usually soak the seals in light oil for at least  1/2 day. Then when I 
get them totally pushed into the slot, I cut the ends off flush with the 
cap with a razor blade.   Then I use a little silicone on a screwdriver 
to put some on the end of the bottom seal when I put them together.  
This is the way we did it in the tractor shop years ago.  However at 
that time we used 3M weatherstrip sealer..  It still works great too.
