Product Description
Shimano 10MW5 Anti-Reverse Pawl (BNT3361) | Mechanical Fail-Safe
The Shimano 10MW5 Anti-Reverse Pawl (BNT3361) is a critical mechanical backup component used in Shimano's low-profile and round baitcasting reels. While modern reels primarily use a one-way roller clutch bearing for anti-reverse, the 10MW5 pawl (often called an "Anti-Reverse Dog") acts as a redundant safety system. It ensures that the handle and gears cannot rotate backward even if the primary roller bearing slips under extreme pressure or fails due to cold weather or contamination.
Precision-stamped from high-tensile stainless steel, the 10MW5 is designed to "catch" the teeth of the anti-reverse ratchet on the drive shaft. This part is essential for maintaining the structural integrity of the reel during a heavy hookset or when fighting powerful fish.

Technical Tip: The anti-reverse pawl is often held in place by two small "friction ears" that wrap around the anti-reverse ratchet. If these ears are bent too far outward, the pawl will not engage. If they are too tight, the reel will feel "heavy" during the retrieve. For precise installation alignment, download the PDF schematics at www.reelschematic.com.
Maintenance & Lubrication Recommendation
The anti-reverse pawl is a "metal-on-metal" contact part. Proper lubrication is vital to prevent the "clicking" noise during retrieve and to ensure the pawl engages instantly when needed. We recommend Deuthlon Lubricants:
-
For the Pawl & Ratchet Teeth: Apply a light coating of Deuthlon Reel Gear Grease. Its high-tack, water-resistant formula stays on the friction surfaces, ensuring quiet operation and protecting the stainless steel from "peening" (rounding of the edges) over time.
-
For the Pivot Post: Use a single drop of Deuthlon Power Cast Oil on the post where the pawl is mounted. This allows the pawl to flip back and forth with zero resistance, ensuring it is always ready to engage.
Why Choose Genuine Shimano 10MW5?
-
Hardness Calibration: Machined to a specific Rockwell hardness that matches the Shimano drive shaft ratchet, preventing one part from prematurely "eating" the other.
-
Corrosion Resistance: Specially treated stainless steel prevents the pawl from rusting onto its mounting post, a common cause of anti-reverse failure.
-
Exact Tension: The friction "ears" are factory-set to the correct width to provide the perfect balance between engagement speed and retrieve smoothness.
