FPV - Brushless Motor Bearing Replacement - Brotherhobby Returner R4 - Quick & Dirty

I've got the original EZO 684-ZZ 4x9x4mm bearings for the brotherhobby returner r4 from ebay ( ).
If you have seen my last 2 videos, you already know that i've had got some vibration issues on my Quads that i never had bevor. I didn't feel the vibrations while flying, but i have seen it on the HD Footages.
So i decided to replace the bearings first, bevor i replace the whole motors. It worked on 3 of 4 Motors. On one Motor i couldn't unscrew the Motor bell.
There is needed a 1,5mm Hex ( ) to unsrew the motor bell.
Tip: it helps to heat the motor bell screw with a soldering iron to release the loctite on the motor bell srew.
This is not a recommendation for replacing the bearings, this issen't the right way - it's just my quick & dirty way to replace the bearings without specials tools.
Be careful with the motor windings, don't touch them with your tools, One slip and the winding might be shot
I will improve my process of the bearing replacement with a matching socket wrenches for the nuts and even try to take the bearings in the freezer first so that they contract and fit easier.
Unfortunately the focus isn't sharp on my video, the objects were too close to the Foxeer Box. The Fish Eye effect isn't perfect for this kind of video as well.
Next time i'll use another camera for this kind of videos.
I hope you like it, like, subsribe, and leave a comment - if you like ;)
