The Chelsea 489 Series Power Take-Off, part number 489XQAHX-P3GH or 489XQAHXP3GH, is built around an 8-bolt one-piece cast iron housing that bolts directly to the transmission opening without an adapter plate, eliminating a common leak path. Intermittent torque capacity for the 489 Series runs 201-300 lb-ft, with output power in the 46-55 HP range. The series features tapered bearings in place of needle bearings for stronger load-carrying capability, and this wire/cable mechanical shift unit includes a 1-1/4" round keyed output shaft. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
