Product Description

DAIWA IDLE GEAR A (F59-2101 / 6F592101)

Restore the power transmission in your heavy-duty electric reel with this genuine Daiwa replacement gear.

The Daiwa F59-2101 Idle Gear A is a vital internal component for Daiwa's large "Dendoh" style electric reels. Located within the side plate assembly, this gear acts as a primary reduction gear, transferring torque from the high-power electric motor to the spool and level wind systems.

If your electric reel motor is running but the spool isn't turning, or if you hear grinding noises under load, a stripped idle gear is a common cause. This is an Original Equipment Manufacturer (OEM) part, manufactured to exact tolerances to handle the immense torque of deep-drop fishing.

Why Replace Your Idle Gear?

In electric reels, the idle gears are often designed as "sacrificial" points to protect the expensive motor and main gears in the event of a sudden lock-up. Over time, heat and heavy loads from deep-dropping for halibut, tilefish, or swordfish can wear down the teeth. Replacing this gear restores the smooth, high-torque winding power your reel was built for.

Tech Tip: When replacing Idle Gear A, inspect the adjacent Idle Gear B and Idle Gear C for wear. It is often best to replace these gears as a set to ensure even mesh and longevity.
