The Chelsea 489QRLZX-D3RB is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed to bolt directly to 8-bolt manual transmission openings on most Eaton Fuller, Mack, and Tremec transmissions without an adapter plate. The one-piece cast iron housing eliminates a potential leak path compared to adapter-plate designs. The 489 Series delivers an intermittent torque rating of 201-300 lb-ft and output power of 46-55 HP, with a 1-1/4" round keyed output shaft. Shift is wire/cable mechanical. Internal parts are common to the Chelsea 442 Series, and the series offers eleven internal speed ratio options across twenty-seven output configurations.
