Product Description
DAM Quick 100-830 – Outside Cycloid Gear, Models 247 & 248 Replacement Part
Product Overview
Ensure the perfect line lay of your vintage German spinning reel with this genuine DAM Quick 100-830 Outside Cycloid Gear. Engineered specifically for the DAM Quick 247 and 248 series, this gear (often referred to as the oscillation gear) is the heart of the reel’s line management system.
Located on the side of the reel body, this gear engages with the drivetrain to power the oscillation slide, moving the spool up and down during retrieval. If your reel is stacking line unevenly, making clicking noises during the spool stroke, or if the oscillation has failed entirely, a worn cycloid gear is often the cause. Installing this factory-correct replacement ensures the cross-winding pattern remains consistent, preventing line dig-in and ensuring long, smooth casts.
