The gearbox support washer provides a stable bearing surface for the hexagon-head bolt, ensuring even distribution of clamping force to the gearbox support bearing bracket. Proper load distribution helps maintain consistent torque retention and prevents localized stress that can lead to fatigue or component deformation.

• Load distribution: Spreads clamping force from the gearbox support bolt to prevent localized stress on the bracket surface.
• Vibration resistance: Helps maintain bolt preload under road vibration and drivetrain movement.
•  Installed on: Gearbox support bearing bracket assembly
•  Quantity required: Typically 1 washer per gearbox support bolt (verify per model and service manual)
