Default Vspec problem

I got the Ofna bearing puller to replace my bearings. Well I got both out, but when I tried to put the new ceramic rear bearing in I put it in backwards. So I was trying to get it out no luck. It is less than a mm from the exit and very stuck. I broke the tool trying to get it out. So can I run it with the bearing backwards? I have put it in the oven and it still won't come out. Any ideas?

Crank up the oven. I don't like going over 300, unless the bearing is really stuck... up to 325 should be ok. And leave it in there for a while (like 20 min).
The aluminum case WILL expand more than the steel bearing.
Just be ready with your oven mitt and the crank when you pull it out of the oven, or anything else that fits. Put it in the bearing and wiggle it out while it's still hot.
PS: I'm assuming that you're taking everything else off the case when swapping bearings... no need to expose any seals to that kind of heat.
