- Carefully un-clip and disconnect the heater cable (A) and the motor cable (B) from their respective edge connectors on the main board.
Note: You may need to use bent nose pliers to assist in removing these connectors.
Ensure to grip on the latching pin at the top before pulling gently in a vertical motion. Do not force it!
- Using a 5mm hex key (do not use a ball-ended driver), slightly loosen the five bolts that secure the motor assembly.
Note: The bolts will be stiff to undo due to being assembled with Loctite 243 at the factory.
Once all the bolts are equally slack, remove them completely and keep safe for refitting later.
- Carefully lift the complete drive assembly up slightly from the chassis to provide access to the encoder connection.
- Carefully un-clip and disconnect the encoder cable (C) from its edge connector on the main board.
Note: Take care when removing this connector. If necessary, disconnect the adjacent Ethernet cable first to provide better access to the retaining clip of the encoder connector. - You can now remove the drive assembly from the chassis and return it to Navtech Radar (using the packaging supplied with the replacement unit).
