The Chelsea 489 Series Power Take-Off Assembly, part number 489XAAHX-W3XD or 489XAAHXW3XD, is an 8-bolt PTO designed to bolt directly to most manual transmissions including Eaton/Fuller, Volvo/Mack, and others without an adapter plate. The one-piece cast iron housing mounts to the transmission's 8-bolt aperture, delivering the same 250 lb-ft intermittent torque capacity as the Chelsea 442 Series. Output is via a 1-1/4" round shaft with key. Shift is accomplished through wire/cable mechanical actuation. Output power reaches 48 HP at 1,000 RPM. The 489 Series uses tapered bearings in place of needle bearings for greater load-bearing capability. A genuine Chelsea part sold by Pro Gear and Transmission.
