Hello everybody,
Im Mike Q, I'm an FNG here this is my first post,
Im not sure if this section of the forum is where I post this question and if not, please point me in the right direction.
On a Mori MH400 I have an ATC that the Main Arm occasionally does not return completely to the Home Position. the key on the gear is just slightly off to the Mag Side of the sensor.
I have replace the dynamic brake contactor/auxiliary with new ones. Talked to Mori, he suggested to check out the Cam and Bearing. Any suggestions or recommendations from experience?? Thanks in advance.

I agree with the cam bearing. Not a fun job if it is a broken cam bearing.
