The Chelsea 489 Series Power Take-Off, part number 489GHAHX-H3XD or 489GHAHXH3XD, is an 8-bolt PTO assembly designed for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec. The integral one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. The 1-1/4" round output shaft with keyway delivers up to 250 lb-ft intermittent torque and 48 HP at 1,000 RPM. Internal components are common to the Chelsea 442 Series, and the kit-style design simplifies service. Greaseable output options help protect against shaft spline fretting and corrosion.
