The Chelsea 489 Series PTO Assembly, part number 489XRAHX-W5XD or 489XRAHXW5XD, is a wire/cable mechanical-shift power take-off built for manual transmissions with an 8-bolt PTO mounting opening, including Eaton Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt aperture, eliminating the adapter plate and reducing potential leak paths. The 489 Series delivers 250 lb-ft intermittent torque, matching the 442 Series torque capacity, with tapered bearings for greater load-bearing capability compared to needle bearing designs. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key accommodates a wide range of driven accessories. A genuine Chelsea part, available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
