I need to service my reel. It's the 2016 Stradic, not the latest version. When I remove the spool assembly, there's a teensy (hex?) screw that pins the rotor nut to the main shaft. Does anyone know what tool I can use to remove it?

 

Thanks.

Not sure of the size but I just loosen the rotor nut so it comes forward to let me access the gear box. the AR clutch shouldn't need any attention if it's working properly.  Two tips: The rotor nut is reverse threaded so go opposite and watch out for the white plastic bail trip on the bottom between the rotor and gear box.  It falls out.

.9mm hex or allen key. Amazon has it. Or file a small paper clip into the hole and unscrew it.
