The Chelsea 489 Series Power Take-Off, part number 489XRITX-H3XQ or 489XRITXH3XQ, is an 8-bolt PTO assembly designed for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. 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. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key accommodates a wide range of pump and accessory configurations. Shift is accomplished via wire/cable mechanical actuation. This PTO shares internal parts with the Chelsea 442 Series, and the kit-style design simplifies service. Call us to confirm proper fit for your transmission and application.
