The Chelsea 489XQHWX-H5XK is an 8-bolt mechanical shift Power Take-Off from the Chelsea 489 Series, designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing bolts straight to the 8-bolt transmission opening, eliminating the adapter plate and reducing potential leak paths. Shift is accomplished via wire/cable mechanical actuation. The output shaft is a 1-1/4" round shaft with key. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 46-55 HP of output power. Available from Pro Gear and Transmission.
