The Chelsea 489 Series Power Take-Off Assembly, part number 489XRITX-A3GH or 489XRITXA3GH, is a wire/cable mechanical shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, which removes a potential leak path compared to adapter-mounted designs. This 489 Series unit shares the same 250 lb-ft intermittent torque capacity as the Chelsea 442 Series and uses tapered bearings in place of needle bearings for greater load capability. The 1-1/4" round output shaft with keyway and the 8-bolt mounting pattern are confirmed for this part. Output power ranges from 46-55 HP (31-40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Compatible transmissions include Eaton/Fuller, Volvo/Mack, and select others. Call us to confirm proper fit for your specific transmission.
