Thank the pinion gear out of the reel and clean the centre out with a cotton bud, the get a permanent marker pen and colour the shaft all around the area that has the bend, let the ink dry and slowly push the shaft into the pinion gear until you feel resistance, pull the shaft back and where the ink is scratched, face it down on a hard surface and tap with a hammer, try it back in the pinion gear again and keep doing this until the shaft runs freely through the pinion gear
