The Chelsea 489XWAHX-A3XD or 489XWAHXA3XD is a 489 Series Power Take-Off Assembly designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift is wire/cable mechanical. The 1-1/4" round output shaft is available with or without a keyway. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
