Product Description
SHIMANO 1048S CLUTCH PAWL SPRING (BNT1307)
Restore Reliable Clutch Engagement
The Shimano 1048S Clutch Pawl Spring (BNT1307) is a critical small spring located within the clutch mechanism of many Shimano baitcasting reels. This spring provides the necessary tension to the clutch pawl, allowing it to interact correctly with the clutch cam and kick lever.
If your thumb bar feels loose, "mushy," or if the reel fails to snap back into gear when you turn the handle after a cast, this spring is often the culprit. It is prone to fatigue or flying off during disassembly. Replacing it with this genuine OEM part ensures your reel's clutch engages positively and crisply every time.

Installation Tip: This spring is very small and under tension. When installing it onto the Clutch Pawl (often part BNT1306), use fine-point tweezers and work in a well-lit area (or inside a clear plastic bag) to prevent the spring from launching across the room if it slips.
