The Chelsea 645KBQX-3XX or 645KBQX3XX is a 645 Series power takeoff assembly built for 6-bolt transmission openings. A defining feature of this series is the 45-degree downward angular offset, which repositions the PTO output to clear chassis components that a standard straight-mount unit would contact. The input gearing is shared with the Chelsea 442 Series, which means existing 442-compatible driveline components may carry over depending on the application. This assembly mounts directly to a 6-bolt transmission opening. Call us to confirm proper fit for your specific transmission and chassis configuration before ordering.
