Product Description
Shimano 10KC0 Worm Shaft (BNT2654) | Cardiff & Corvalus Replacement
The Shimano 10KC0 Worm Shaft (BNT2654) is a high-precision drive component essential for the level wind oscillation system in Shimano baitcasting reels. This shaft features a double-helix groove pattern that guides the line guide pawl back and forth across the spool, ensuring a perfectly even line lay during every retrieve.
A smooth-functioning worm shaft is critical for maximizing casting distance and preventing line "dig-in" under heavy drag. If your level wind is stuttering, sticking at one side, or making a grinding noise, it is likely that the worm shaft is worn or damaged. Replacing it with this genuine Shimano OEM part restores the factory-smooth performance of your reel's line management system.

Maintenance & Lubrication Recommendation
Worm shafts are partially exposed to the elements, making them prone to collecting grit, sand, and salt. Proper lubrication is the most effective way to prevent premature wear. We highly recommend Deuthlon Lubricants:
-
For General Use: Apply Deuthlon Reel Gear Grease to the grooves of the worm shaft. Its high-tack, dust-resistant formula provides a smooth glide and prevents debris from sticking to the moving parts.
-
For High-Speed Performance: Use a drop of Deuthlon Power Cast Oil on the worm shaft bearings or bushings at either end to minimize friction and increase casting efficiency.
Why Choose Genuine Shimano 10KC0?
The 10KC0 (BNT2654) is manufactured to the exact tolerances required for Shimano's drive train synchronization.
-
Synchronized Timing: Matches the gear pitch of your idle gears perfectly to prevent stripping.
-
Corrosion Resistance: The specialized alloy is treated for use in both freshwater and brackish environments.
-
Extended Gear Life: A new worm shaft prevents the line guide pawl from tracking incorrectly, which saves the rest of your level wind assembly from unnecessary wear.
