The Chelsea 489 Series Power Take-Off Assembly, part number 489ZCDAX-A5XQ or 489ZCDAXA5XQ, is an air shift PTO built on an 8-bolt mount for direct fitment to Eaton Fuller, Volvo/Mack, and Tremec gearboxes. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening without an adapter plate, reducing potential leak paths and cutting installation time. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Output is through an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft, rotated 90 degrees. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts share commonality with the Chelsea 442 Series. A genuine Chelsea part sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
