Description
The Chelsea 489 Series Power Take-Off Assembly, part number 489ZRAHX-A3XK or 489ZRAHXA3XK, fits most manual transmissions equipped with an 8-bolt PTO mounting aperture, including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, reducing potential leak paths. Intermittent torque capacity for the 489 Series is 201-300 lb-ft, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4″ round with key. Shift is via wire/cable mechanical mechanism. Internal components are common with the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission and application.
