Description
The Chelsea 489XUAHX-A6XK or 489XUAHXA6XK is a 489 Series Power Take-Off assembly built 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 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit uses tapered bearings rather than needle bearings for greater load-bearing capability. The wire/cable mechanical shift drives a 1-1/4″ round output shaft with key. Intermittent torque for the 489 Series is rated 201-300 lb-ft, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, simplifying service.
