The Chelsea 489 Series Power Take-Off Assembly, part number 489XSAHX-A5AF or 489XSAHXA5AF, mounts directly to 8-bolt manual transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible transmissions. The one-piece cast iron housing bolts on without an adapter plate, reducing potential leak paths and cutting installation time. Intermittent torque capacity for the 489 Series runs 201-300 lb-ft (301-400 Nm), matching the torque capacity of the 442 Series. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output is an SAE B 2 or 4-bolt flange with a 1" 15-tooth SAE BB shaft, and the unit uses an air shift. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The 489 Series is suited for utility trucks, dump truck and trailer applications, snow and ice removal equipment, and fire and rescue vehicles. For service documentation, refer to the 489 Series Parts List (HY25-2442-M1_US) and Chelsea Service Manual (HY25-6489-M1/US) available through Parker Chelsea's product support resources.
