Reel Housing, Main Gear and Shaft
•Inside the housing of the fishing reel are the gears. The reel housing is kept in place by three or four screws, depending on the model of reel. Once the housing is removed you will have access to the gears. You will also see the shaft, which is the rod that travels from the gear housing to the rotor cup where the line spool is located. The shaft pushes the line spool up and down when the reel turns, so that the line is distributed evenly onto the line spool
