The Chelsea 489XRAHX-A3XK or 489XRAHXA3XK is an 8-bolt Power Take-Off assembly from the Chelsea 489 Series, designed to fit most manual transmissions with an 8-bolt PTO mounting aperture, including Eaton/Fuller, Volvo/Mack, and Tremec units. The integral 8-bolt housing eliminates the need for an adapter plate, reducing potential leak points. Shift type is wire/cable mechanical, with output power rated at 46-55 HP (31-40 kW). The 1-1/4" round output shaft (with key option available) delivers shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, simplifying parts sourcing for shops already familiar with that platform. Call us to confirm proper fit for your transmission.
