The Chelsea 489GSAHX-V3AF or 489GSAHXV3AF is a 489 Series power take-off assembly built 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 one potential leak path. Wire/cable mechanical shift is the specified shift type for this unit. The 1-1/4" round output shaft (with key) delivers up to 250 lb-ft intermittent torque, matching the torque capacity of the Chelsea 442 Series. 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, and the kit-style design simplifies service.
