The Chelsea 489 Series Power Take-Off Assembly, part number 489XHDAX-A5XK or 489XHDAXA5XK, mounts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton Fuller, Volvo/Mack, and others. The one-piece cast iron housing eliminates the adapter plate found on older designs, reducing potential leak paths and cutting installation time. The 489 Series delivers 250 lb-ft intermittent torque, the same capacity as the Chelsea 442 Series, with output shaft power of 24 HP at 500 RPM and 48 HP at 1000 RPM. This unit uses a wire/cable mechanical shift and accepts a 1-1/4" round output shaft with keyway. Internal components are common to the 442 Series, simplifying parts inventory. Call us to confirm proper fit for your transmission and application.
The Chelsea 489 Series fits a wide range of vocational applications including utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles. Tapered bearings replace the needle bearings used in some competitive designs for improved load-bearing capability. The series offers twenty-seven output options including Chelsea's 360-degree rotatable flange with greaseable shaft, reducing pump shaft spline wear and corrosion. Eleven internal speed ratios are available across the 489 Series. The kit-style design and parts commonality with the 442 Series mean many shops can service this PTO with components already on the shelf.
