Product Description
Mitchell 82594 Drive Gear – High-Performance Main Gear
The Mitchell 82594 Drive Gear is the mechanical heart of several iconic Mitchell spinning reels. As the primary component responsible for converting handle rotation into rotor speed and spool oscillation, the drive gear is subject to the highest levels of torque and friction.
This specific gear is part of the "Advanced" or "Second Generation" 300-class family. Unlike the earlier brass gears found in vintage 300s, the 82594 is typically a high-strength alloy or specialized composite engineered for the improved mechanical tolerances of the "A," "C," and "S" series reels. Replacing a worn drive gear is the only way to eliminate "gear growl" and restore a heavy-duty, smooth-turning retrieve.

Compatible Models
The 82594 is a highly versatile gear used in the modernized 300-series chassis and the premium 900-series models. It is a verified fit for:
-
Mitchell 300A: The modernized "Advanced" version of the classic 300.
-
Mitchell 300C: The ball-bearing high-performance model (requires specific shimming).
-
Mitchell 300S: The skirted-spool variant.
-
Mitchell 410A: High-speed versions of the 300-class chassis.
-
Mitchell 900 / 910: The premium "heavy-duty" spinning series designed for saltwater and large freshwater species.
Technical Insight: The 82594 gear must be perfectly meshed with the pinion gear and the oscillation planetry gears. If you are replacing this gear due to wear, it is highly recommended to inspect the oscillation slide and the small planetary gears for damage, as a worn drive gear often leaves micro-shards of metal throughout the housing.
Professional Maintenance & Lubrication
To ensure the maximum lifespan of your new drive gear and to achieve that signature "silent" Mitchell retrieve, proper lubrication is mandatory.
-
Gear Teeth: Apply a generous but even coat of Deuthlon Reel Grease to the teeth of the 82594 gear. Its specialized "Dust-Shield" properties provide a high-pressure cushion between the teeth, preventing metal-on-metal galling and significantly reducing mechanical noise.
-
Drive Shaft: Apply a drop of Deuthlon Reel Oil to the drive gear shaft where it passes through the housing or the ball bearing. This ensures the handle turns with minimal startup inertia.
Why Choose Genuine Mitchell 82594?
The teeth of the Mitchell 82594 are cut to precise angles to match the 300-series planetary system. Aftermarket gears often suffer from "rough spots" or improper pitch, which can lead to rapid wear of the pinion gear. Using a genuine factory replacement ensures that the gear's timing remains perfect, maintaining the level line-lay and power-retrieve performance of your 300A or 910.
