The Chelsea 489 Series Power Take-Off, part number 489XQAHX-V5XD or 489XQAHXV5XD, is an air shift PTO built on an 8-bolt one-piece cast iron housing that mounts directly to the transmission opening without an adapter plate, reducing potential leak paths. The 489 Series fits most manual transmissions with an 8-bolt aperture, including Eaton Fuller, Mack, and Tremec. Tapered bearings replace needle bearings for greater load-bearing capability, and intermittent torque capacity for the series runs 201 to 300 lb-ft. Shaft power output is rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Internal parts are common to the Chelsea 442 Series, making this a versatile, field-serviceable unit.
