Product Description
Mitchell 81164 Axle – Genuine Replacement Part
The Mitchell 81164 Axle (also known as the main shaft) is a precision-machined core component specifically designed for vintage Mitchell "Planematic" spinning reels. This central shaft is responsible for the vertical oscillation of the spool, which is the foundation of the reel's line lay and drag performance.
A bent, pitted, or scarred axle can cause "sticky" oscillation or uneven winding, which leads to wind knots and poor casting distance. Replacing your worn shaft with this genuine-spec part restores the unique Planematic movement and factory-smooth operation of your classic Mitchell reel.
Product Specifications & Compatibility
The 81164 Axle is engineered with the specific dimensions and tolerances required for the Planematic gearing system, which utilized an elliptical oscillation pattern to prevent line bedding.
Compatible Models:
-
Mitchell 314 (Right-hand wind, Planematic version)
-
Mitchell 315 (Left-hand wind, Planematic version)
-
Mitchell 304 (Selected Planematic-equipped versions)
Technical Note: Because the 304/314 family saw various internal design changes over the years, we strongly recommend verifying your reel's specific parts list using the high-resolution PDF schematics at www.reelschematic.com.
Technical Cross-Reference
To assist in sourcing through different inventory systems or modern databases, this part is identified by the following alternate part numbers:
-
Alternate Part Number: 811164-1
Key Features
-
Hardened Steel Construction: Machined to maintain high structural integrity under drag pressure and resist bending.
-
Planematic Precision: Features the exact machining required to interface with the Planematic slide and oscillation gear.
-
Corrosion Resistance: Finished to provide a smooth, low-friction surface that resists oxidation in freshwater environments.
-
OEM Fit: A direct drop-in replacement that restores original factory tolerances for spool alignment.
Maintenance & Lubrication Recommendation
The axle is a high-travel surface that benefits significantly from high-performance lubrication. To maximize the lifespan of your new 81164 Axle, we recommend Deuthlon products:
-
Deuthlon Reel Oil: Apply 1-2 drops along the shaft where it passes through the pinion gear. This ultra-slick oil ensures the spool oscillates with minimal resistance, even during a high-speed retrieve.
-
Deuthlon Reel Grease: Apply a small amount to the connection point where the axle meets the oscillation slide. This provides a waterproof barrier and prevents metal-on-metal wear at the drive connection.
