Product Description
Shimano 10JT6 Oscillating Pawl (RD 11743) | Ultegra XSB Series
The Shimano 10JT6 Oscillating Pawl is a high-precision internal component essential for the "Aero Wrap II" or "Super Slow Oscillation" systems found in Shimano's long-cast spinning reels. This pawl sits within the oscillating slider and tracks the grooves of the worm shaft, translating the rotation of the gears into the steady back-and-forth movement of the spool.
A worn or chipped pawl is the primary cause of uneven line lay, spool "stuttering," or the spool becoming stuck at the top or bottom of its stroke. Replacing this small but vital part restores the flawless line management required for maximum casting distance and tangle-free performance.

Maintenance & Lubrication Recommendation
Because the pawl is under constant friction against the worm shaft, lubrication is the most important factor in its longevity. For optimal performance, we recommend Deuthlon Lubricants:
-
For the Worm Shaft & Pawl: Apply Deuthlon Reel Gear Grease. Its high-tack, low-friction properties allow the pawl to glide through the worm shaft grooves without the grease being "pushed" out of the track, even under the pressure of a heavy retrieve.
-
For the Pawl Housing: A drop of Deuthlon Power Cast Oil inside the slider before inserting the pawl will ensure it can pivot freely, preventing it from binding or causing premature wear on the worm shaft threads.
Why Choose Genuine Shimano 10JT6?
Shimano’s oscillating systems rely on microscopic tolerances. Using the original RD 11743 ensures:
-
Perfect Tracking: The tip of the pawl is machined to the exact width and depth of the worm shaft grooves.
-
Line Lay Precision: Maintains the specialized cross-wrap pattern that prevents line digging on the spool.
-
Worm Shaft Protection: Using a generic or poorly finished pawl can "eat" the expensive worm shaft, leading to a much more costly repair.
