Orion Vortex. . . problem
 

I've had this Orion Vortex 10.5 Motor since 2010.
-now it's run'n with a buzz'n noise
-I uninstalled the motor from the chassis, removed the rotor; put it back together then reinstalled it. It's still buzz'n

I think it's the bearings.

Did anyone have or had this problem?

Thank You.

Thanks anyway.
I purchased a Team Orion VST2 10.5 Lightweight Motor (item # 28293)
