Description
The Chelsea 489ZRITX-H3XK or 489ZRITXH3XK is a 489 Series Power Take-Off assembly designed for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton/Fuller, Volvo/Mack, and other compatible units. The one-piece cast iron housing bolts directly to the transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift is wire/cable mechanical. The 1-1/4″ round output shaft is available with keyway. The 489 Series shares internal parts with the Chelsea 442 Series and delivers intermittent torque in the 201-300 lb-ft range, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. Tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your transmission.
