The Chelsea 489 Series Power Take-Off, part number 489ZQDAX-A5GH or 489ZQDAXA5GH, is a wire/cable mechanical shift PTO built on an 8-bolt mounting pattern. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening on compatible manual transmissions including Eaton Fuller, Mack, and Tremec, eliminating the adapter plate and reducing potential leak paths. The 489 Series carries an intermittent torque rating of 201-300 lb-ft (301-400 Nm) and delivers shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key accepts a range of output configurations. Internal parts are shared with the Chelsea 442 Series, and tapered bearings replace needle bearings for greater load capacity. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 489 Series PTO is suited for utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue applications. The kit-style design simplifies servicing, and with eleven internal speed ratios available across the 489 Series, this PTO covers a wide range of vocational and municipal equipment needs. For parts manual information, refer to Parker document 489 Series Parts List HY25-2442-M1_US or the 489 Series Service Manual HY25-6489-M1/US.
