I have the Raven AC-3 and at one point I heard a noise which I located to one of the motors.
The pulleys on top of the motors are attached to the spindles via an Allen Key screw so I loosened this screw and pulled the pulley up slightly and re-tightened the screw.
No more noise.
It turned out that the pulley was pushed too far down the spindle and rubbed against the top of the motor casing as it turned?
An easy fix to try.
