The Chelsea 489 Series Power Take-Off Assembly, part number 489XSAHX-A5GF or 489XSAHXA5GF, is an 8-bolt PTO designed to mount on manual transmissions including Eaton/Fuller, Volvo/Mack, and other compatible units. The integral 8-bolt housing eliminates the need for an adapter plate, reducing potential leak paths. This unit uses wire/cable mechanical shift and delivers up to 250 lb-ft (339 Nm) intermittent torque. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft is available with a greaseable SAE B 2- or 4-bolt flange mount. Internal parts share commonality with the Chelsea 442 Series, and the kit-style design simplifies service. Call us to confirm proper fit for your application.
