- Carefully un-clip unclip and disconnect the multi coloured motor ribbon cable (A) from its edge connector on the main board. Note how the cable is routed so that the new motor cable can be routed in the same fashion on reassembly.
- 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 (B) from its edge connector on the main board. Ensure to grip on the latching pin at the top before pulling gently in a vertical motion.
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).
