The Chelsea 489 Series Power Take-Off, part number 489GQAHX-A5AF or 489GQAHXA5AF, is an 8-bolt PTO assembly built for most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission aperture, eliminating the need for an adapter plate and reducing potential leak paths. This unit uses wire/cable mechanical shift and features a 1-1/4" round output shaft with key. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM and 48 HP at 1000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series, making service and parts sourcing straightforward.
