The Chelsea 489 Series Power Take-Off Assembly, part number 489XSAHX-A5AF or 489XSAHXA5AF, mounts directly to 8-bolt manual transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible transmissions. The one-piece cast iron housing bolts on without an adapter plate, reducing potential leak paths and cutting installation time. Intermittent torque capacity for the 489 Series runs 201-300 lb-ft (301-400 Nm), matching the torque capacity of the 442 Series. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4" round configuration with key, and the unit uses a wire/cable mechanical shift. Cross-references include 1450-489XSAHXA5AF and S-20286.
