Repairing an electric car is not far away:
This is a removed bearing, and the specifications of the front wheel and the rear wheel are not the same
Sand the sandpaper with an open sandpaper
Effect after polishing (look at the edges)
Very unprofessional tool
Disassemble the motor
Small wool stove rear wheel
This is the little donkey
Repair the electric car, but just remove the rear wheel, take apart the electric motor, polish the magnet block (increase the magnetic force), because the protagonist of this matter - the bearing (the last picture of that thing) has not been bought back! Repair reasons, a year of battery can not run 10 kilometers, 4 years of old electric vehicles, so the bearing is very suspicious, dismantled and turned is obviously not moving! It should be that the motor aging bearing is broken. The line price is more than 100 bar, I purely studied it, the first demolition has no experience, it took 1 hour to disassemble. Hopefully, the new bearings can be repaired, because there is no instrument to measure the battery, and the battery suddenly drops off easily without considering it first. So this time it's purely a journey of discovery. The tools in hand are also not easy to make.
