The Chelsea 489 Series Power Take-Off, part number 489GFAHX-W3SQ or 489GFAHXW3SQ, mounts directly to 8-bolt manual transmission openings from Eaton Fuller, Volvo, Mack, and others without an adapter plate, removing one potential leak path. The one-piece cast iron housing delivers the same 250 lb-ft intermittent torque capacity as the Chelsea 442 Series. Output shaft is a 1-1/4" round with key. Shift is wire/cable mechanical. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 489 Series uses tapered bearings rather than needle bearings for stronger load-bearing capability, and internal components are common with the 442 Series, keeping service parts inventory simple.
