The Chelsea 489 Series Power Take-Off Assembly, part number 489ZFAHX-A3XK or 489ZFAHXA3XK, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo, and Mack without an adapter plate, eliminating a common leak path. Shift type is wire/cable mechanical. The 1-1/4" round output shaft with keyway delivers up to 48 HP at 1,000 RPM or 24 HP at 500 RPM. Intermittent torque rating for the 489 Series reaches 250 lb-ft, matching the capacity of the 442 Series. The one-piece cast iron housing uses tapered bearings for greater load capacity than needle-bearing designs. Internal parts share commonality with the 442 Series, simplifying service.
