The Chelsea 489 Series Power Take-Off Assembly, part number 489XSAHX-A6XK or 489XSAHXA6XK, mounts directly to 8-bolt transmission openings on Eaton Fuller, Mack, Tremec, and other compatible manual transmissions without an adapter plate, eliminating one potential leak path. The one-piece cast iron housing delivers the same intermittent torque capacity as the 442 Series - up to 250 lb-ft (339 Nm) - while the tapered bearing design provides greater load-bearing capability than needle bearings. This unit shifts via wire/cable mechanical actuation and uses a 1-1/4" round output shaft with key. Shaft power output is 24 HP at 500 RPM and 48 HP at 1000 RPM. The kit-style construction shares internal parts with the 442 Series, simplifying service. A genuine Chelsea part, available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
