Default Replacing Engine's rear bearings?

I'm trying to replace the rear bearings in my SportWerks.21 and my Werks TLB7Pro.
both of them are blown and Ive removed all the internals except for the outer ring of the rear bearings...

Q1. How do I remove the ring without damaging the case?

Q2. Do I need a special tool?

You need to heat the crank case up and that outer ring will fall out.

You obviuosly haven't noticed that RC tech has been getting slower for a couple of months now. You need to wait for it to load instead of clicking on the damn mouse when you get impatient!

LOL, I do get impatient sometimes...

I have tried to heat the case but with no luck... I guess I'll keep trying!

Cook the case in a toaster oven with the rear bearing facing down. heat to about 350-400. and if it does not just fall out give it a tap on something wooden. like a 2*4
the wood is so you dont mess up the case.
then put your new front and rear bearings in.

as a last resort, take a dremel and with a small round cutter, cut 2 small knotches just big enough to expose the race 180 degrees apart on the back side and then take a small punch or screwdriver and tap it out rotating knotches every other hit to push out evenly. I have done this on many engines and engines run fine afterward.
