The Chelsea 489ZLDAX-A6XK or 489ZLDAXA6XK is an 8-bolt power take-off from the Chelsea 489 Series, designed for manual transmissions including Eaton Fuller, Mack, and Tremec. The 489 Series uses a one-piece cast iron housing that bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. The series carries an intermittent torque rating of 201 to 300 lb-ft and delivers up to 46-55 HP output. Shift type is wire/cable mechanical. The output shaft is a 1-1/4 inch round shaft with key. Strong tapered bearings replace needle bearings for greater load-bearing capability. Available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
