Product Description
Mitchell 81743 Gear Bridge | Fits 600 Series & 624 Conventional Reels
Restore the mechanical precision of your vintage saltwater reel with the genuine Mitchell 81743 Gear Bridge. This critical internal chassis serves as the mounting platform for the main gear, pinion gear, and drag system. In the high-torque environment of a Mitchell 624, the gear bridge is responsible for maintaining perfect alignment between the drive train components, ensuring a smooth retrieve and consistent drag pressure.
Crafted to original French engineering standards, this replacement bridge is essential for repairing reels with bent mounting posts, stripped threads, or salt-pitting that can cause internal gear misalignment.

Installation & Maintenance
The gear bridge is the "heart" of your reel's transmission. When installing the 81743, it is the optimal time to clean the entire gear train and apply modern, high-performance lubricants to extend the life of your vintage equipment.
Recommended Lubrication Protocol:
-
Deuthlon Reel Gear Grease: Apply a thin, even coat to the bridge posts and the teeth of the gears once mounted. Deuthlon's formula provides a "ceramic-like" coating that significantly reduces mechanical noise and vibration under load.
-
Deuthlon Reel Power Oil: Use a drop on the drive shaft port and the anti-reverse dog pivot to ensure instant engagement and smooth rotation without the "stickiness" often found in older petroleum-based lubes.
Why Choose Genuine Mitchell Parts?
The Mitchell 624 is built for heavy-duty saltwater applications. Using an original 81743 Gear Bridge ensures that the tolerances between the bridge and the side plate remain perfect. Aftermarket or worn bridges can lead to "gear slop," which causes premature wear on the expensive main gear and pinion. This genuine part preserves the legendary cranking power and durability of your Mitchell reel.
