How to Remove the Pan Motor
Referring to Figure Chapter
1. Detach connector.
On the Unicard board, detach the 7-pin cable
connector from P6 (see figure for location).
2. Remove the pan motor.
Remove the two M3x8, Phillips head screws
securing the pan motor bracket to the carriage
assembly, then remove the motor and set it aside.
Note: Outline the bracket of the old motor with a
pencil before removing to simplify the alignment
of the new motor.
3. Reverse steps to reassemble the dome.
!
WARNING!
Be careful not to bend connector pins!
When reattaching the cable to P6, be
careful not to bend or break a connector
pin.
Note: Realign gear mesh using a 1/4-watt
resistor or .05mm (.02”) diameter drill rod.
!
WARNING!
When putting in a new motor, be
careful to properly mesh the motor
and pan gears!
Failure to do so can destroy both the
motor and pan gear. Verify that the pan
gear turns freely!
