The Chelsea 489 Series Power Take-Off Assembly, part number 489ZFDAX-V5XK or 489ZFDAXV5XK, is an 8-bolt PTO designed for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt transmission aperture, eliminating the need for an adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical, with an electric over air shift option available. The output shaft is a 1-1/4" round with key. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); shaft power reaches 48 HP at 1,000 RPM. Strong tapered bearings replace the needle bearings used in older designs for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series. Cross-references include S-11029 and TG8D-M6506-P3KX. Call us to confirm proper fit for your transmission.
