The Chelsea 489XUAHX-A3XK or 489XUAHXA3XK is a 489 Series Power Take-Off assembly built for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating a potential leak path. Wire/cable mechanical shift is standard on this unit. Output shaft is a 1-1/4" round with key. Intermittent torque rating 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. Continuous torque is de-rated 30% from the intermittent figure. The 489 Series uses tapered bearings in place of needle bearings and shares internal components with the Chelsea 442 Series. Cross-references include S-11289 or S11289 and TG8S-U6815-A1KX or TG8SU6815A1KX. Call us to confirm proper fit for your application.
