You should see some of the stuff I've seen on multi-million dollar equipment.
And this stuff gets inspected very carefully.
You should be ok if you don't go over board and use the whole tube. Just need about 1/16" thick bead towards the outside edge, and around the bolt holes. Just make sure everything is clean. No oil dripping from the inside of the motor, running onto the mating surface. And you will be good.
