The Chelsea 489 Series Power Take-Off, part number 489XHAHX-U5SQ or 489XHAHXU5SQ, is an 8-bolt mount PTO engineered for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec. The integral 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. Shift is wire/cable mechanical. The output shaft is a 1-1/4" round with key. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm), matching the 442 Series rating. Shaft power output is 24 HP at 500 RPM and 48 HP at 1000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability.
