The 3Racing SAK-D5632/LB spur gear cover is intended to reduce debris ingress to the spur area without obstructing access for adjustments. Its light blue finish acts as a clear visual reference when checking gear clearance at the pit.
By limiting abrasive contact with the spur gear this cover helps maintain consistent gear behaviour and reduces the need for early replacement. The design aims to balance protection with minimal interference to drivetrain tuning.
Install the cover with accurate alignment to avoid any contact with the spur or accessory pinions. Confirm full rotation clearance and recheck mounting torque after initial running to prevent vibration induced loosening.
