The Chelsea 489 Series Power Take-Off, part number 489XRAHX-V5XQ or 489XRAHXV5XQ, is an 8-bolt PTO assembly designed for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. Its one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and the potential leak path that comes with it. Intermittent torque rating for this series is 250 lb-ft (339 Nm), matching the torque capacity of the Chelsea 442 Series. The output shaft is a 1-1/4" round shaft with key, and shift actuation is wire/cable mechanical. Output power runs 46-55 HP, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the 442 Series, and the kit-style design makes field service straightforward. Call us to confirm proper fit for your transmission and application.
