The Chelsea 489 Series Power Take-Off Assembly, part number 489XQAHP-A3RB or 489XQAHPA3RB, mounts directly to 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible manual transmissions without an adapter plate, eliminating a common leak path. This unit delivers intermittent torque in the 201-300 lb-ft range (250 lb-ft series rating; verify against application pages for your specific configuration) and output power of 46-55 HP. The wire/cable mechanical shift and 1-1/4" round output shaft with key suit a wide range of vocational applications including dump trucks, utility trucks, and snow and ice removal equipment.
