Product Description
Mitchell 81084 Transfer Gear – Precision Timing for High-Speed Systems
The Mitchell 81084 Transfer Gear (sometimes referred to as the intermediate or oscillation drive gear) is a specialized internal component found in Mitchell’s high-performance and high-speed spinning reels. In the unique Mitchell planetary drive system, the 81084 gear acts as a critical link, transferring rotational force from the main drive gear to the oscillation mechanism and the pivot gears.
Because high-speed models like the 400 and 440 series operate at much higher RPMs, this gear is engineered to maintain perfect mechanical timing. A worn transfer gear is often the cause of "rhythmic clicking" or uneven spool travel, as even one micro-chipped tooth can throw the entire planetary synchronization out of alignment.

Technical Insight: The 81084 gear is part of a high-speed "Gear Set" that includes the 81085 Drive Gear, 81090 Pinion, and 81083 Pivot Gears. When one of these gears is replaced due to wear, it is highly recommended to inspect the others; high-speed internals "wear in" as a unit, and mixing a new gear with heavily worn companions can cause noise and premature failure.

Professional Maintenance & Lubrication
In high-speed reels, the transfer gear spins rapidly. Proper lubrication is the only way to prevent the metal-on-metal "whine" often associated with older high-speed Mitchells.
-
Gear Teeth: Apply an even coating of Deuthlon Reel Grease to the teeth of the 81084 gear. Its "Dust-Shield" properties are essential here, creating a high-pressure film that stays on the gears during fast retrieves and cushions the mechanical impact of the teeth meshing.
-
Central Pivot Post: Apply a drop of Deuthlon Reel Oil to the post upon which the 81084 gear rotates. This reduces startup inertia and ensures the gear can spin freely, contributing to the "feather-light" feel of the handle.
Why Choose Genuine Mitchell 81084?
The Mitchell 81084 gear is machined with a specific tooth pitch and hardness to handle the torque of high-speed retrieves without stripping. Aftermarket gears often lack the precise hardening of the original, which can lead to rapid "rounding" of the teeth and lost motion in the spool's oscillation. Using a genuine factory replacement ensures your Mitchell Match or 400-series reel remains a precision instrument for years to come.
