The Chelsea 489XLAHX-A5RJ is an 8-bolt Power Take-Off unit from the Chelsea 489 Series, designed for most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. This PTO uses tapered bearings rather than needle bearings for greater load-bearing capability and features an air shift. The 489 Series delivers an intermittent torque rating of 201-300 lb-ft and output shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series.
