The Chelsea 489XRITX-A5XD or 489XRITXA5XD is a 489 Series Power Take-Off assembly built for manual transmissions with an 8-bolt PTO aperture, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical, with an electric-over-air shift option available in the series. The output shaft is a 1-1/4" round with key. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internally, components are common to the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 489 Series PTO is suited for utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles. The kit-style design simplifies servicing, and internal components are interchangeable with the Chelsea 442 Series. Twenty-seven output options are available across the 489 Series, including a 360-degree rotatable flange with greaseable shaft.
