Product Description
Mitchell 81357 Axle – Genuine Replacement Part
The Mitchell 81357 Axle (also referred to as the main shaft) is a vital heavy-duty component designed for Mitchell’s legendary saltwater spinning reels. This axle serves as the backbone of the reel’s spool oscillation, providing the strength required to withstand high-drag pressures and the corrosive environment of coastal fishing.
A bent or worn axle can lead to poor line lay, friction during the retrieve, and reduced casting distance. Installing a new 81357 axle restores the smooth, vertical movement of the spool, ensuring your vintage powerhouse remains battle-ready for years to come.
Product Specifications & Compatibility
The 81357 Axle is specifically engineered for the large-frame "Saltwater" series, known for their massive line capacity and robust internal gearing.
Compatible Models:
-
Mitchell 302 (Standard saltwater model)
-
Mitchell 303 (Left-hand wind equivalent)
-
Mitchell 402 (High-speed saltwater model)
-
Mitchell 403 (Left-hand high-speed equivalent)
Technical Note: These large-frame reels often underwent internal revisions. To ensure this axle matches your specific oscillation slide and gear set, please consult the technical diagrams at www.reelschematic.com.

Key Features
-
Reinforced Steel Construction: Specially treated to resist bending under the extreme torque of saltwater game fish.
-
Precision Machined Surfaces: Reduces friction as the shaft passes through the pinion gear and into the oscillation block.
-
Saltwater Grade Finish: Designed to provide superior resistance against oxidation and salt buildup.
Maintenance & Lubrication Recommendation
Because the axle is a high-travel part exposed to the elements, proper lubrication is critical to prevent wear. We recommend using Deuthlon products for maximum protection:
-
Deuthlon Reel Oil: Apply a light coating to the length of the axle. This ultra-slick lubricant ensures the spool oscillates effortlessly even under heavy loads.
-
Deuthlon Reel Grease: Apply a small amount to the point where the axle connects to the oscillation cross-block. The grease’s "Aqua Shield" properties will prevent saltwater from migrating into the main gearbox along the shaft.
