The Chelsea 489 Series Power Take-Off Assembly, part number 489XUAHX-S3XK or 489XUAHXS3XK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and others. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path compared to earlier designs. This unit uses a wire/cable mechanical shift and delivers up to 250 lb-ft intermittent torque, matching the torque capacity of the Chelsea 442 Series. The 1-1/4" round output shaft with key is greaseable to reduce spline fretting and corrosion over time. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the 442 Series, keeping service straightforward. Call us to confirm proper fit for your specific transmission and application.
