The Chelsea 489 Series Power Take-Off Assembly, part number 489XCAHX-A5XQ or 489XCAHXA5XQ, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec models. The one-piece cast iron housing eliminates the adapter plate found on earlier designs, reducing both installation time and potential leak paths. Intermittent torque rating for the 489 Series is 201-300 lb-ft (301-400 Nm); shaft power output reaches 24 HP at 500 RPM and 48 HP at 1,000 RPM. This unit uses a wire/cable mechanical shift and features a 1-1/4" round output shaft with keyway. Internal components are common to the Chelsea 442 Series, and the tapered bearing design provides greater load capacity than needle-bearing alternatives.
