Excellent video, I am getting the Super Stock BZ motor and will be replacing the ball bearings straight away. Your method for "sandwiching" in the bearing is a great idea.

Bmx and tamiya, can’t go wrong!

I have had terrible luck getting the ball bearings out of the metal bell. The plastic and bell is fine those basically fall out and I can replace them basically by just pushing them in with my finger but the bushing that is in the metal side of the motor will not come out. I can bang it out, and it really does take a lot of force to get the bushing out and using the arbor method that you have, which I tried myself I deformed and destroyed two bearings that I tried to insert into the housing. I even attempted to use the wood from a broom handle, turn the metal upside down and press it in from the magnet side , and it doesn’t work I tried using a puller broke the bearing I tried, banging them in with a wooden doll, destroyed the bearing

its like tamiya just hates ball bearings or something lol.

Thanks! Nice video! I wonder if this will work for my TT-02 🤔

they are cheap skates. if the bearings sell for $40 and the motor for $60, what kid is gonna buy $100 motor for their rc?
