What is wrong with your player? Would just a replacement motor work? The RF-300C-11440 I do not have in stock. The gears I may have on other motors. What is a gear? The gear fits over the shaft and has slpined tteth that engage with a sprocket gear so theat a transfer of force is put on the driven gear. In other words look for a plactic or metal toothed metal ring. I need the number of teeth and the outside diameter of the gear.
