Product Description
Mitchell 81734 Left Outer Ring – Genuine Replacement Part
The Mitchell 81734 Left Outer Ring (also listed in some catalogs as 81742) is a critical structural and protective component designed for the non-handle side (Left Side) of the Mitchell 600-series conventional reels. This metal ring acts as a reinforcing "hoop" that secures the composite side plate to the frame posts, providing the necessary rigidity to prevent the reel from twisting or flexing during a heavy fight.
Because the left side of the reel houses the clicker mechanism, the 81734 ring features specific cutouts and mounting points that differ from the right-side ring. Replacing a pitted, bent, or corroded ring is essential for maintaining both the structural integrity and the classic aesthetic of these vintage saltwater workhorses.
Product Specifications & Compatibility
The 81734 is engineered for the robust "600" family of reels. It is designed to withstand the harsh conditions of boat decks, including salt spray, high humidity, and physical impacts.

Technical Note: While very similar in appearance to the right-side ring (81741), the 81734 is not interchangeable. The left ring must accommodate the clicker button assembly.

Key Features
-
Reinforced Structural Support: Prevents "side plate spread," ensuring the spool remains perfectly centered and doesn't rub against the housing.
-
Corrosion-Resistant Finish: Typically features heavy chrome plating to resist the "green" oxidation (verdigris) common in saltwater environments.
-
Precision Machined: Features exact countersunk holes for the 81709 side plate screws, ensuring they sit flush and don't snag on fishing line or clothing.
-
OEM Standard: A direct replacement part that preserves the original factory strength and tolerances of your Mitchell reel.
Maintenance & Lubrication Recommendation
Saltwater often traps between the metal ring and the side plate, leading to hidden corrosion. We strongly recommend using Deuthlon products during your restoration:
-
Deuthlon Reel Grease: Apply a thin, even layer to the underside of the 81734 ring before mounting it. Its "Aqua Shield" technology creates a waterproof gasket that prevents salt crystals from forming between the metal and the plate.
-
Deuthlon Reel Oil: Use a light wipe of oil on the exterior chrome surface. This helps shed water and protects against "boat rash" and surface pitting caused by prolonged exposure to marine air.
