The Chelsea 489 Series Power Take-Off Assembly, part number 489XFABX-A6XK or 489XFABXA6XK, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec -- no adapter plate required. The one-piece cast iron housing eliminates a potential leak path while delivering the same intermittent torque capacity as the 442 Series (250 lb-ft / 339 Nm). Output shaft is a 1-1/4" round with key. Wire/cable mechanical shift and an electric-over-air shift option are available within the series. Shaft power rates at 24 HP at 500 RPM and 48 HP at 1000 RPM. Kit-style construction and internal parts shared with the 442 Series simplify service. Sold by Pro Gear and Transmission.
