The Chelsea 489 Series Power Take-Off, part number 489ZFDAX-C5XK or 489ZFDAXC5XK, is an 8-bolt PTO built for most manual transmissions including Eaton Fuller, Mack, and Tremec. Its one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate found on older designs and reducing potential leak paths. The 489 Series delivers intermittent torque in the 201-300 lb-ft range with a series-characteristic capacity of 250 lb-ft, matching the torque capacity of the 442 Series. Output shaft is a 1-1/4" round with key. Shift is accomplished via wire/cable mechanical mechanism. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load capability. Call us to confirm proper fit for your specific transmission.
