The Chelsea 489DQMCX-56RK is an 8-bolt Power Take-Off unit 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, cutting installation time and reducing potential leak paths. Shift type is wire/cable mechanical. The series delivers intermittent torque of 201 to 300 lb-ft and output power of 46 to 55 HP, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Available with a 360-degree rotatable flange and greaseable shaft output option to reduce spline fretting and corrosion. Common internal parts with the Chelsea 442 Series simplify service and parts inventory. Sold by Pro Gear and Transmission.
