Models This Part Fits
The Mitchell 82590 side plate is designed for the "Newer" generation of spinning reels, primarily those produced after the initial classic run. It is a direct fit for:
-
Mitchell 300A (Newer Version)
-
Mitchell 300S (Skirting Spool Version)
Technical Note: Because Mitchell produced various versions of the 300 model over several decades, always verify your specific production year. You can view high-resolution PDF schematics for these newer models at www.reelschematic.com.
Maintenance & Lubrication
For maximum performance and to prevent "gear chatter" common in spinning reels, we recommend a full service during the installation of this side plate.
-
Deuthlon Reel Grease: Apply a thin, even coat to the inner rim of the side plate and the main gear face. This ceramic-based grease stays in place even under high heat or heavy pressure.
-
Deuthlon Reel Oil: Apply a single drop to the handle shaft port and the side plate screws. This prevents "freezing" of the screws due to oxidation and ensures the handle turns with minimal resistance.
Optimized for Durability
Unlike older cast-iron or early alloy plates, the 82590 (1111696) is designed with modern tolerances in mind. It provides the necessary clearance for newer oscillation sliders and high-speed gearing systems, making it the preferred choice for restoring "Newer" style Mitchell reels to factory-new condition.
