The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-A3AK or 489XFAHXA3AK, mounts directly to 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible manual transmissions without an adapter plate. The one-piece cast iron housing delivers the same intermittent torque capacity as the 442 Series, rated at 250 lb-ft (339 Nm), using strong tapered bearings in place of needle bearings for greater load-bearing capability. Output is a 1-1/4" round shaft (with key option), and the shift type is wire/cable mechanical. Output power reaches 48 HP at 1,000 RPM. The kit-style design shares internal parts with the 442 Series, making field service straightforward. Call us to confirm proper fit for your transmission and application.
