Line Spool

• The reel's line spool is removed by unscrewing the plastic drag knob on top of the spool. The line spool does more than just hold the line you put on the reel. It also houses the drag system, which acts as the brakes on the reel. The drag system is what slows down a strong fish without breaking your line.
  
  

Drag System

• The drag system on your Daiwa fishing reel is located directly below the plastic drag knob on top of the line spool. This series of alternating metal and fiber washers is kept in place by a retaining spring. The spring is located in a groove just above the washers and is easily removed with a small screwdriver by gently prying it out of its groove. The drag system works by compressing the fiber drag washers when you tighten the drag knob. The increased tension makes it more difficult to pull line from the reel when it is in gear.
  
  

Reel Handle

• Many Daiwa spinning reels feature a reel handle that can be used on either side of the reel. The way the manufacturers accomplished this is by designing a square rod on the end of the handle. The rod passes through the reel housing and the main gear from either side of the reel. It is held in place by a small, capped screw that fits into the threads on the end of the square rod.
  
  

Bail Wire, Bail Spring and Line Roller

• Spinning reels lay line on a stationary spool by spinning the line around the spool. The bail wire is a hinged mechanism that opens to let line flow freely from the spool when casting and closes when you turn the handle and begin to retrieve the line. When closed over the line, the bail wire spins around the spool wrapping the line neatly in place. On one end of the hinge for the bail wire there is a spring that helps close the bail and keep it shut while you are reeling. On the other end of the hinge for the bail wire you will find the line roller. The line roller's job is to eliminate the friction generated by the line sliding across the bail wire as it is pulled around the spool. With its hourglass shape, the line roller spins on a small axle as line is pulled across it.
  
  

Reel Housing, Main Gear and Shaft

• Inside the housing of the Daiwa fishing reel are the gears. The reel housing is kept in place by three or four screws, depending on the model of Daiwa 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.
