Product Description
Mitchell 81894 Rotor (Rotating Head) - High-Speed Replacement for 497 & 497A
The Mitchell 81894 Rotor, also referred to as the Rotating Head, is a heavy-duty, high-performance component designed specifically for the Mitchell 497 series. As the central rotating assembly of the reel, it is responsible for the rapid line retrieval and precise line lay required in high-speed saltwater fishing.
Because the Mitchell 497 is the high-speed, Right-Hand Wind (RHW) version of the large-frame Mitchell family, this rotor is dynamically balanced to eliminate vibration at high RPMs. It serves as the critical mounting point for the bail assembly, ensuring that the bail trips consistently and the reel maintains its balance even under the extreme pressure of surf casting or offshore angling.

Key Features
-
High-Speed Balancing: Specifically engineered to prevent "rotor wobble" during the fast retrieves typical of the 497 gear ratio.
-
Corrosion-Resistant Finish: Treated with a marine-grade coating to withstand constant exposure to saltwater, humidity, and sand.
-
Reinforced Bail Mounts: Features heavy-duty pivot points designed to support the large bail wires and heavy-duty springs required for saltwater game.
-
Precision Threading: Machined for a perfect fit on the high-speed pinion gear, ensuring no slip or play during high-torque retrieves.
Maintenance & Installation Tip
Due to the high rotational speeds and the saltwater environment the 497 is designed for, choosing the right lubricant is vital for the longevity of the rotor and bail mechanism.
Recommendation: We strongly recommend Deuthlon Lubrication for all Mitchell 497 maintenance. Use Deuthlon Power Gear Grease on the rotor nut and the internal bail trip ramps. For the bail hinges and the line roller assembly, apply Deuthlon Cast Lube Oil to ensure a friction-free retrieve and superior protection against salt crystallization.
Technical Support & Schematics
To ensure the counterweights, bail springs, and trip levers are correctly seated within the 81894 rotor, it is essential to follow the original manufacturer's diagrams. You can find the complete PDF schematics for the Mitchell 497 and 497A at www.reelschematic.com. Accurate assembly is necessary to maintain the high-speed balance of this rotating head.
