The Chelsea 489 Series Power Take-Off Assembly, part number 489XSAHX-S3XK or 489XSAHXS3XK, mounts directly to the 8-bolt transmission opening using a one-piece cast iron housing that eliminates the need for an adapter plate, reducing potential leak paths and installation time. 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 supported by tapered bearings for greater load-bearing capability than needle-bearing designs. Compatible transmissions include Eaton Fuller, Eaton Endurant, Mack, and Tremec manual transmissions. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Call us to confirm proper fit for your specific transmission and application.
