What This Forward Gear Bearing is Used For
This tapered bearing is used inside compatible Yamaha lower unit assemblies to support the forward gear assembly.
The forward gear bearing helps maintain proper gear alignment, supports drivetrain load, and allows the forward gear to operate correctly inside the gearcase.
Counter-rotation lower units place unique loading demands on the gearcase, making proper bearing condition critical for drivetrain reliability.
Worn or damaged lower unit bearings may contribute to gearcase noise, metal contamination, vibration, gear wear, or lower unit failure.
Replacing worn bearings during lower unit rebuilds helps restore proper gearcase operation and drivetrain reliability.
