Description
The Chelsea 489XCAHX-A3GA or 489XCAHXA3GA is a 489 Series Power Take-Off assembly featuring an integral 8-bolt cast iron housing that mounts directly to the transmission opening without an adapter plate, reducing potential leak paths. Shift type is wire/cable mechanical. The 1-1/4″ round output shaft with key delivers up to 48 HP at 1,000 RPM and an intermittent torque rating of 201-300 lb-ft for the series. Compatible transmission families include Eaton/Fuller, Volvo/Mack, and Tremec manual gearboxes with an 8-bolt PTO aperture. Tapered bearings replace needle bearings for greater load capacity, and internal parts share commonality with the Chelsea 442 Series. This is a genuine Chelsea part sold by Pro Gear and Transmission.
