The Chelsea 489 Series Power Take-Off Assembly, part number 489XWITX-H5XK or 489XWITXH5XK, mounts directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate required on some other PTO designs, reducing potential leak paths. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm), with an application-specific rating of 250 lb-ft; continuous-duty torque should be de-rated 30% per Chelsea application data. Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The wire/cable mechanical shift, 1-1/4" round output shaft with key, and tapered main bearings distinguish the 489 Series from needle-bearing designs. Internal parts share commonality with the Chelsea 442 Series. Call us to confirm proper fit for your transmission.
