Has anyone taken apart an actuator arm? Long story short, I took the actuator arm (24" - Von Weise motor) off of my 10' Unimesh dish to see if it actually worked. This arm has been on the dish for I don't know how long and is a little seized. I have taken what I can apart and put power to the motor. The motor works but the arm is stuck. I want to take the arm right off of the motor housing so I can soak it overnight and see if I can get it to move (before I have to buy a new one). How do I get the arm off of the motor housing?
