Maintenance & Installation Tip
To ensure the longevity of your reel's internal drive train and the smooth operation of the side plate seal, we highly recommend using professional-grade lubricants during installation.
-
Deuthlon Reel Grease: Apply to the internal contact points of the side plate where it meets the main gear to reduce friction and prevent wear.
-
Deuthlon Reel Oil: Use a drop on the handle port and external screws to prevent corrosion and ensure easy disassembly in the future.
Why Choose Genuine Mitchell Parts?
Using the 81037 (1111663) side plate ensures that your reel maintains its original tolerances. Aftermarket or ill-fitting plates can lead to gear misalignment, increased "play" in the handle, and premature wear of the oscillation system. Keep your vintage gear running like new with authentic replacement components.
