The Chelsea 489 Series Power Take-Off Assembly, part number 489ZFDAX-A5AK or 489ZFDAXA5AK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing eliminates the adapter plate found on older designs, reducing potential leak paths and cutting mounting time. Intermittent torque capacity for the 489 Series matches the 442 Series at 250 lb-ft (339 Nm); shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4" round with key. Internal gear components are shared with the 442 Series, making service parts straightforward to source. Call us to confirm proper fit for your transmission and application.
