Product Description
Anglers looking to maintain or restore the smooth, powerful retrieve of their trusted Abu Garcia Ambassadeur reels can now source the genuine Abu Garcia 1116904 Crosscut Pinion Gear. This essential drivetrain component is a factory-specified part, engineered to precise tolerances to ensure perfect meshing and flawless operation in a wide range of classic and modern Ambassadeur C3 and C4 series reels.
The pinion gear is a critical part of a reel's internal mechanics, working directly with the main gear to transfer power from the handle to the spool. A worn or damaged pinion gear can result in a rough or noisy retrieve, loss of power, and inconsistent gear engagement. The 1116904 is a "crosscut" pinion, referring to the specific tooth design that allows it to properly engage with the main gear and the spool, a design characteristic of reels equipped with the IAR (Instant Anti-Reverse) bearing.
Manufactured from high-quality, durable brass, this pinion gear is built to withstand the torque and stress of countless casts and tough battles with hard-fighting fish. Replacing a worn pinion gear with this genuine part can make an older reel feel new again, eliminating gear noise and restoring that "out-of-the-box" smoothness and power.
