Product Description

SHIMANO YOKE (BNT1627 / 1047L)

Fix your slipping clutch and restore crisp engagement with this genuine Shimano replacement yoke.

The Shimano 1047L Yoke (Schematic Part Number BNT1627) is a vital internal component of the clutch mechanism found in Shimano's larger round baitcasting reels, specifically the 400 and 700 sizes. This fork-shaped plastic part cradles the pinion gear, lifting it off the spool shaft when you press the thumb bar (free spool) and dropping it back down to engage the drive gear when you turn the handle.

If your reel is stuck in free spool, makes a grinding noise when casting, or if the clutch lever feels loose, a worn yoke is a primary suspect. This is an Original Equipment Manufacturer (OEM) part.

Product Features

• Part Number: BNT1627

• Alternate Part Number: 1047L (Package Code)

• Part Name: Yoke / Pinion Yoke

• Material: High-Density Wear-Resistant Composite

• Function: Controls the vertical movement of the pinion gear to engage/disengage the spool.

• Fitment: Specific to large-frame Round Baitcasters (400/700 series).

Why Replace Your Yoke?

The yoke features slanted ramps that interact with the clutch cam. Every time you cast, these plastic ramps slide against hard metal or composite cam surfaces. Over time, friction wears grooves into the ramps, preventing the pinion gear from lifting high enough to clear the spool pin. This causes that dreaded "grinding" sound during a cast or prevents the reel from going into free spool altogether.

Tech Tip: The yoke works in tandem with the Pinion Gear and two Yoke Springs. When replacing the yoke (BNT1627), always check the condition of your pinion gear teeth and ensure the springs still have strong tension.
