The Chelsea 489DQMBX-56RK or 489DQMBX56RK is an 8-bolt power take-off (PTO) from the Chelsea 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Eaton Endurant, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing mounting time and potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP, with a wire/cable mechanical shift. The round 1-1/4" keyed output shaft and tapered roller bearings provide durable load-handling across demanding vocational applications such as dump trucks, utility trucks, and snow and ice equipment.
