Installation & Maintenance Recommendation
When replacing the bail wire, it is essential to ensure the bail hinge moves freely without binding. We recommend cleaning the rotor pivot points and applying fresh lubrication during installation.
Recommended Lubrication: For the best results in both fresh and saltwater, we recommend Deuthlon lubricants:
-
Deuthlon Semi-Fluid Grease: Apply to the internal bail spring and trip mechanism. This grease resists water washout and ensures the bail snaps shut consistently.
-
Deuthlon Cast Lube (Ceramic): Apply a drop to the line roller and bail hinge screws. Its low-friction formula ensures the bail arm pivots effortlessly and the roller spins freely.

Tech Tip: If your bail feels stiff after installation, check the alignment of the wire. A bent wire can pull the rotor arms inward or push them outward, creating friction. The wire should line up naturally with the mounting holes before tightening.
