Product Description
Fin-Nor QAF053-01 O/S Gear (Trophy 80)
Maintain precise line management and smooth spool stroke with the genuine Fin-Nor QAF053-01 O/S Gear (Oscillation Gear). Designed specifically for the Fin-Nor Trophy series, this internal gear is the critical link in your reel's oscillation system, ensuring the spool moves evenly up and down to stack line correctly.
As an Original Equipment Manufacturer (OEM) component, this gear is machined to exact factory specifications. Replacing a worn or stripped oscillation gear is essential for fixing issues such as uneven line lay, "stacking" at the top or bottom of the spool, or a reel that feels "rough" during the retrieve.

Installation & Schematics

It is highly recommended to clean the old grease from the housing and apply fresh reel grease to the new gear teeth during installation.
