The Chelsea 489 Series Power Take-Off, part number 489ZLDAX-S5SQ or 489ZLDAXS5SQ, is an 8-bolt PTO designed for most manual transmissions including Eaton Fuller, Mack, and Tremec. 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. Shift type is wire/cable mechanical. The 489 Series carries an intermittent torque rating of 201-300 lb-ft and delivers up to 55 HP output. Tapered bearings replace needle bearings for greater load-bearing capability. Available in a 1-1/4" round shaft with key output configuration. Call us to confirm proper fit for your application.
