The Chelsea 489 Series Power Take-Off, part number 489GRAHX-A3XQ or 489GRAHXA3XQ, is an 8-bolt PTO assembly built for most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round with key. The 489 Series carries the same intermittent torque capacity as the 442 Series at 250 lb-ft (339 Nm). Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the 442 Series, simplifying parts sourcing and service.
