MITCHELL 81596 COVER PLATE – Mitchell 406 & 407 High-Speed Series
The Mitchell 81596 Cover Plate (also referred to as the Side Plate) is a critical exterior housing component for the classic Mitchell 406 and 407 high-speed spinning reels. Designed to protect the internal gear train from contaminants while maintaining the structural alignment of the drive gear, this plate is essential for the smooth operation of your vintage reel. Crafted with the durability required for saltwater and heavy-duty freshwater use, the 81596 plate is a direct OEM-specification replacement part.

Maintenance & Performance Optimization
To ensure a watertight seal and prevent the side plate screws from seizing due to corrosion, proper lubrication during installation is highly recommended.
We recommend Deuthlon Lubricants for all Mitchell restoration and maintenance:
-
Deuthlon Power Gear Grease: Apply a very light film to the inner rim of the cover plate where it meets the housing to create a moisture barrier.
-
Deuthlon Reel Orchid Oil: Apply a single drop to the threads of the side plate screws (Part #81611) before tightening to ensure easy removal during future servicing.
