Maintenance & Installation Guide
When removing the side plate for service, it is the perfect time to clean and re-lubricate your reel's "heart." For maximum protection against wear and corrosion, we recommend using Deuthlon Lubrication:
-
Deuthlon Power Gear Grease: Apply a thin layer to the interior rim of the side plate and the main drive gear teeth to ensure silent operation and moisture resistance.
-
Deuthlon Reel Orchid Oil: Use a drop on the side plate screw threads during reassembly to prevent future seizing or corrosion.
Regularly inspecting the side plate for cracks or warping ensures that your gears remain perfectly aligned, extending the life of your vintage tackle.
