Help!! 9xl makes a loud noise??

i have only had this up to 160* but it is acting up , so i tried my 9l and all is well with my esc. , went back to the 9xl with 5s and when i go full throttle it is like a stripped gear the motor makes a loud sound, i also added 5.5mm plugs but im sure my joints are good.... also when it happens the esc. lights go to flashing green then red

Q...did i seperate the magnet, and how can i safely take it apart to check

I would follow this:

How to Replace Both Bearings in a Feigao Motor.



You will need two things.
A wooden dowel about 1/2" wide by 4 plus inches long.
A retaining glue or ca.

The back motor plate is held in with retaining glue.

To remove the rear bearing plate (side opposite the motor shaft), You are going to have to tap the front motor shaft on something solid. This will force the back plate off. Once the backplate is off your going to have to remove the rotor. We use a pair of pliers with rubber ends, so not to damage the shaft. But it can also be pushed out. Be careful not to damage or scratch the windings at all! Once the motor is disassembled the bearings are going to need to be pressed or pushed out. The stock bearings will get ruined on the way out.

Once both bearings are out, clean up the bearing slot. Replacing the bearing on the rear plate is easy. Make sure its lined up straight and push it in. The front bearing is a bit more difficult. Lining up the bearing straight is crucial. Than use the dowel to tap the bearing in place. Than assemble the motor, using the retailing glue or ca to glue it together. Take care not to damage the wires when putting the rear plate back on.

If it makes the noise only when you hit the throttle hard, the rotor probably came apart from the shaft. This happened two times on my 9xl motor. I sent it to Mike and he fixed it for me.

thanks so much for the info

jnev, thats what its doing, ill take it apart and see if it can be fixed

anyone know what i can use to bond it back to the shaft?

thanks again

so it was seperated, every thing looks good though



i did a search and it looks like i will try the metal/concrete epoxy loctite to reglue it to the shaft, but i still have a ?????

Q...do i try to line up the black line on both of the magnets?... it seems as if they are opposite poles so i think not, and also does the end cap need to line up with the other end cap, they have stuff in them for balancing the rotor

thanks
