Product Description
DAM Quick 104-688 Pinion Gear, 550N
Part Number: 104-688
Item Type: Reel Repair Part / Pinion Gear
Maintain the brute strength of your heavy-duty tackle with the DAM Quick 104-688 Pinion Gear. Engineered specifically for the massive DAM Quick 550N, this pinion gear is the critical link between the main drive system and the rotor. As one of the largest reels in the N-Series lineup, the 550N requires a pinion gear capable of withstanding extreme torque and the heavy pressure of saltwater surf casting or big game fishing.
A worn pinion gear in a heavy-duty reel can lead to catastrophic failure under load, characterized by grinding noises, rotor wobble, or a "rough" retrieve. Replacing this component with a genuine part ensures your reel retains the structural integrity and smooth power transfer necessary for fighting large fish. This gear is precision-machined to exact tolerances to handle the high-stress environment of the 550N gear box.
Key Features:
-
Heavy-Duty Design: Built to manage the high-torque demands of the 550N large-capacity spinning reel.
-
Precision Machining: Ensures a perfect mesh with the main drive gear for maximum cranking power.
-
Wear Resistant: Constructed from durable alloy to resist deformation and saltwater corrosion over time.
-
Direct Fit: OEM specifications guarantee seamless installation into the pinion bearing assembly.
Model Compatibility:

-
DAM Quick 550N
Note: The 550N is a specialized large-frame reel. This pinion gear is significantly larger than those found in the 110N-440N series and is not interchangeable with smaller models.
