Product Description

SHIMANO 1009C WORM BUSHING (REAR) (RD19976)

Stabilize Your Worm Shaft Oscillation

The Shimano 1009C Worm Bushing (Rear) is a genuine OEM synthetic bushing designed to support the rear end of the worm shaft (oscillating gear) in many modern Shimano spinning reels. Located at the bottom of the reel body (rear end), this bushing ensures the worm shaft rotates centrally and smoothly, facilitating the even "up and down" stroke of the spool.

While durable, this bushing can wear over time, leading to excessive play in the worm shaft. Symptoms of a worn rear bushing include a "knocking" sound during retrieval or uneven line lay on the spool. Replacing this part restores the tight tolerances required for precision oscillation.

Upgrade Tip: Many anglers choose to replace this bushing with a specific ball bearing to further reduce friction and improve winding sensitivity (check your reel's specific bearing size requirements, typically 3x6x2.5mm for this position on many 2500-4000 size reels).
