The Chelsea 489 Series Power Take-Off Assembly, part number 489ZQDAX-V4GF or 489ZQDAXV4GF, is a direct-mount PTO designed for manual transmissions with an 8-bolt aperture, including Eaton/Fuller, Mack, and Tremec gearboxes. The integral one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit shifts via wire/cable mechanical actuation and delivers up to 250 lb-ft intermittent torque with a 1-1/4" round output shaft. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Common internal parts with the Chelsea 442 Series simplify rebuilding.
