The Chelsea 645XKXX-3XX or 645XKXX3XX is a Power Take-Off assembly designed for 6-bolt transmission openings. Its defining feature is a 45-degree downward angular offset that repositions the PTO body to clear frame rails, hydraulic lines, or other components that would interfere with a straight-mount installation. Input gearing is shared with the Chelsea 442 Series, which broadens parts interchangeability across your fleet. Mounting footprint is 6-bolt to 6-bolt, matching the transmission opening directly. Dimensions measure 7.75 in. high by 10.75 in. wide by 10.75 in. long. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your specific transmission and chassis before ordering.
