Pulleys usually have a set screw. If there is no set screw, you may have to heat up the pulley with a heat gun and tap the shaft that the pulley sits on with a hammer. Just make sure the motor mount fastening screws to the motor are removed before using the hammer.
Don’t use a battery puller, the flanges on the pulley are aluminum and will bend before the pulley moves. You have to use heat then a large flat head screwdriver and pry the pulley off with brute force. Make sure the two set screws on the pulley are taken off first.
It’s mostly the torque, just a bit of heat to soften the thread locker from the set screws. I used a lighter and held it to the pulley for a minute. It’ll come off just use a bit of force. I’ve taken the entire drive train apart.
Just took the board out with only 1 motor, the other still connected.
For some reason it begins to spin when the board is shaken and get max power … seems like a short …
So now i know for sure i just need to get the motor off and replace it.
I wouldn’t be surprised if that pulley is glued on. Without the presence of a set screw or any type of retaining clip somethings holding it on. If its glue, try heat and pull.
When you figure it out and fix it, would you mind post how you did it and what parts you used on this thread?
I’m trying to put together a thread of just repairs and upgrades on chinese boards. There seem to be lot of people buying these and needing to upgrade or repair them. I want this thread to be like a transition into building your own board from scratch. Learn as you go situation. Lol
