Okay. It's hard to pull the bearing carrier out if you don't loosen the top two bolts on each side. (Contrary to popular opinion, re-tightening those bolts will re-establish the seal.) A thin putty knife can be used to initially lift the assembly up, but be carful not to destroy those copper shims. And when you can get a screw driver in there, be sure to pry it up evenly on all sides, a little at a time.
I'd be a good idea to change the top seal at the same time.

PS: It's possible the endplay of the crankshaft might be different with the new carrier. You can measure this with a dial indicator. Lift the entire motor from the crankshaft, zero the indicator, lower motor back down and gently tap the flywheel. The reading will be the new endplay. You're looking for about 10 to 20 thousandths.
