Product Description
Fin-Nor CO315-01 Main Shaft Assy – Sportfisher FS40 Replacement Part
Product Overview
Restore the structural integrity and smooth oscillation of your saltwater spinning reel with this genuine Fin-Nor CO315-01 Main Shaft Assy. Engineered specifically for the Fin-Nor Sportfisher FS40, this heavy-duty central shaft is the backbone of your reel’s spool assembly.
The main shaft supports the entire drag system and spool, moving vertically to ensure even line lay during retrieval. Due to the extreme loads placed on Fin-Nor reels during battles with heavy saltwater game, the main shaft can eventually bend or warp. A bent shaft often results in spool wobble, rubbing against the rotor, or uneven drag pressure. Replacing it with this factory-original assembly ensures your FS40 operates with the straight, rigid alignment necessary for peak performance.

Schematic Reference
To visualize how this main shaft connects to the oscillation slider and gear, please consult the official reel diagrams. You can locate the detailed schematic for the Fin-Nor Sportfisher FS40 at www.reelschematic.com.
Note: When replacing the main shaft, we highly recommend inspecting the Oscillation Slider (the block the shaft attaches to) and the Pinion Gear inner bore. Debris or old grease in these areas can hinder the movement of the new shaft.
