This is replacement motor for older Athearn Blue Box or RTR locomotive motors, not Genesis. Flywheels are Hex drive not the old ball and finger style that came on earlier models. If your loco already has Hex drive couplings you should be able replace motor and reuse original couplings that came with the loco. Make sure you put couplings back where they came out, one side might be a different length.
If your loco has old ball and finger couplings you need to use our #12034 Hex coupling combo set: https://ppw-aline.com/collections/miscellaneous-re-powering-parts/products/12032
We recommend getting new set of Athearn screw in motor mounts (#40002) to replace the really old ones that pushed into frame and not screwed in. #40002 https://ppw-aline.com/collections/miscellaneous-re-powering-parts/products/40002-40002-athearn-rtr-replacement-motor-mounts-for-all-models-except-switchers-rs3s
