Description
The Chelsea 489XXAHX-V3XD or 489XXAHXV3XD is a 489 Series Power Take-Off assembly designed for manual transmissions with an 8-bolt PTO mounting opening, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating that extra potential leak path. This unit ships with a wire/cable mechanical shift and a 1-1/4″ round output shaft with key. The 489 Series carries the same 250 lb-ft intermittent torque rating as the 442 Series and uses tapered bearings for load handling. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the 442 Series, simplifying service. Call us to confirm proper fit for your transmission.
