The Chelsea 489 Series Power Take-Off Assembly, part number 489KHAHX-A6XK or 489KHAHXA6XK, is built around a one-piece cast iron housing that bolts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton Fuller, Volvo/Mack, and others. The integral housing eliminates the adapter plate found on many competing designs, reducing potential leak paths and cutting installation time. This unit delivers the same intermittent torque rating as the 442 Series, up to 250 lb-ft (339 Nm), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Shift is accomplished via wire/cable mechanical actuation. The 1-1/4" round output shaft supports keyed mounting. Internal parts are common with the Chelsea 442 Series, simplifying parts sourcing. Call us to confirm proper fit for your transmission and application.
