Mamba Motor bearing replacement?

Has anyone been able to open up a Mamba motor? Are there any tricks. I know it is very difficult. I've actually done it once before, but I had a very very, hard time. I need to replace a bearing and $45 to send it to CC is way too much imo to replace a bearing.

Unscrew the 3 bolts on the endbell and gently tap the rotor shaft on a table or something. This will push the endbell off. After that, it is quite straight forward.

The end bell screws are WAY loctited... You'll need to get one of those small butane torches and a high qualitly (new) exact sized screwdriver. I like to use my 1/4" socket style snap-on bit, but you can get something decent from a Lowes or Home Depot or a tool shop.

First you'll want to mount the can in a vise (you can cut a V into a block of wood and secure the block and the motor to a table with a c-clamp if need be).

Then clean ANY dirt or debris out of the screw heads. Check the fit of the bit.

Get the pocket torch out and heat up the screw, hotter the better but be careful to not damage the finish on the can.

Use a piece of ice to rapidly cool the screw back down, this will harden the head a bit to help it not strip out. it will also (hopefully) cool the screw and the can at different rates so that the loctite will loosen up a bit. After it's cool I like to tap and the head if the screw by putting the driver in place then tapping the back of the driver (you can hit it pretty hard but again a little caution).

Now you're ready to get the screw out- as follows, put the driver in the screw, apply a little torque but don't try to break it loose, patience. Take the pocket torch again and this time start to heat the end plate just above the screw ( not realy flame to metal, but not real far away either, mabey 1/4" or so) heat, back off, heat, back off... you want the heat to spread to the loctite arount the screw threads, but not soften the screw.

Soon, with patience the screw will just let loose and start turning without much force at all. Take it all the way out while it's still hot or the loctite will harden again.

P.S. the bearing is 11x5x11mm and you can get a ceramic sealed bearing they use for heli tail shafts that is rated for 5,000hours at 80,000rpm for like $12

I think you mean the bearings are 5x11x5.
Those screws on the motor can break easily but, I was able to get them out get it opened up. I heated up the screws with my soldering iron and that did the trick. They came out without too much effort. My torch I felt was a little too big for the job and my soldering iron gets up to 840*F.
After I got the screws out. I put a piece of rubber around it and put it in the vice. Put a piece of wood on the shaft and popped it with a hammer a couple of times and the end bell opened up.
Thanks for the help.
