CHANGING TURNTABLE MOTOR AND
REMOVING AC-500 FROM ITS CASE
Slide a screwdriver under the chrome handle cover and snap it off, exposing the two bolts which hold the handle in place. Remove these bolts. On the opposite side of the unit, locate the two rubber feet. Remove the bolts that hold these feet in place.
Make sure the tone arm is locked in its clip. LIft out the platter, and set it aside. Turn the set on its right side and pull the front of the chassis away from the case about 3 or 4 inches CAUTION! - PULLING THE FRONT TOO FAR TO THE RIGHT OR FORWARD BEFORE PULLING THE BACK TO THE RIGHT CAN CAUSE PERMANENT DAMAGE. Push the back forward just far enough to clear the RCA jack on the rear. Pull the back out until it JUST clears the case. There are two cables plugged into the power supply, note the location of the plugs and unplug them. The power supply will remain in the case. Slide the chassis to the right and out of the case.
Locate the tension spring which provides the spring tension to hold the motor assembly up so that the drive wheel contacts the underside of the platter. Remote the nuts and washer from this bolt, remove the spring and the motor assembly will swing out so that you can get at it.
Unsolder the three leads, the two going to the motor and the one ground lead. Remove one of the hex bolts holding the motor mount to the bracket, slide the grommet off the other bolt and the motor will come out. Remove the two bolts holding the bracket to the motor.
Install the replacement motor by following above instructions in reverse order.
