Product Description
Mitchell 81942 Rotor – Genuine Replacement for 331 & 331A "Otomatic" Series
Restore the specialized performance of your left-hand retrieve automatic-trip reel with the Mitchell 81942 Rotor. This authentic replacement part is specifically engineered for the Mitchell 331 and 331A series. As the core rotating component for the "Otomatic" left-hand models, this rotor houses the bail assembly and serves as the mechanical interface for the signature automatic bail release system.
Precision-balanced for left-hand retrieve (right-hand crank) operation, the 81942 rotor is essential for maintaining an even line lay and a wobble-free retrieve. Whether you are repairing a vintage match reel or completing a restoration, this genuine part ensures the exact factory tolerances required for the 330-series chassis.

Compatible Models
The Mitchell 81942 rotor is precision-manufactured for the mid-sized automatic-trip chassis in a left-hand configuration. It is a verified fit for:
-
Mitchell 331 (Left-hand Otomatic / Automatic Bail)
-
Mitchell 331A (Later production variants)
-
Mitchell Match 331 (Select left-hand variants)
Technical Insight: The 331 series features a mirrored internal trip mechanism compared to the 330. Using a right-hand rotor (like the 82629) on a 331 reel will prevent the automatic bail from functioning and may cause internal damage.

Professional Maintenance & Lubrication
The "Otomatic" system involves intricate lever movements within the rotor. To ensure the bail fires with lightning speed and remains responsive, high-performance lubrication is mandatory.
-
Bail Trip Mechanism: Apply Deuthlon Reel Oil to the bail arm pivot points and the internal automatic trip lever. This ultra-low friction lubricant prevents the mechanism from becoming "sluggish" due to old grease or salt spray, ensuring a crisp, instant engagement.
-
Pinion & Rotor Interface: During installation, apply a light coat of Deuthlon Reel Grease to the pinion threads and the rotor nut. Its specialized "Dust-Shield" properties protect the main shaft interface from grit and moisture, ensuring the rotor remains balanced and easy to service.
Why Choose Genuine Mitchell 81942?
A rotor must be perfectly factory-weighted to match the internal oscillation speed of the 331 chassis. The Mitchell 81942 provides the precise internal clearance required for the specialized left-hand bail-trip arm. Using a genuine factory replacement ensures that the trip ramp aligns perfectly with the housing, preserving the unique mechanical reliability and collector value of your vintage 331A.
