Product Description
Shimano 10K1W Clutch Cam (BNT1795) | Genuine Replacement Part
The Shimano 10K1W Clutch Cam (BNT1795) is a critical internal component designed for the high-precision engagement systems of Shimano baitcasting reels. This part acts as the primary mechanical pivot that transitions the reel between the "free spool" (casting) and "engaged" (retrieving) modes.
Precision-molded from high-impact, low-friction polymer, the 10K1W cam ensures that the clutch plate and yoke move in perfect synchronization. Over time, the constant friction of shifting can wear down the cam's lobes, leading to a "sticky" thumb bar or a reel that fails to engage properly when the handle is turned. Replacing a worn cam with this genuine OEM part restores the crisp, reliable shifting action your Shimano reel was engineered to provide.

Technical Note: Because the clutch cam is the heart of the shifting assembly, it must be oriented correctly relative to the clutch pawl and spring. For an exact exploded view and assembly sequence, you can download the original PDF schematics at www.reelschematic.com.
Maintenance & Lubrication Recommendation
Since the clutch cam is subject to high-frequency sliding friction, using the correct lubricant is essential to prevent the polymer from wearing down or becoming brittle. We highly recommend Deuthlon Lubricants:
-
For the Cam Lobes: Apply a light coating of Deuthlon Reel Gear Grease. Its high-tack, "dust-resistant" formula provides a smooth sliding surface that won't wash away under heavy use or water intrusion.
-
For the Pivot Post: A single drop of Deuthlon Power Cast Oil on the post where the cam rotates will ensure the thumb bar returns to the "up" position with minimal spring tension required.
Why Choose Genuine Shimano 10K1W Parts?
Using the original BNT1795 ensures that your reel’s shifting timing remains perfect.
-
Factory Tolerances: Prevents "clutch kick-back," where the reel accidentally engages mid-cast.
-
Structural Integrity: The polymer is chemically resistant to standard reel cleaners and environmental contaminants.
-
Smooth Operation: Maintains the light, effortless thumb bar pressure Shimano is known for.
