The Chelsea 489 Series Power Take-Off Assembly, part number 489XHAHX-A5SQ or 489XHAHXA5SQ, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo, and Mack applications. The one-piece cast iron housing eliminates the need for an adapter plate, cutting potential leak paths. This unit shifts via wire/cable mechanical actuation and carries an intermittent torque rating of 201-300 lb-ft for the series. Output is a 1-1/4" round shaft (with key option available), and shaft power measures 24 HP at 500 RPM and 48 HP at 1,000 RPM. The kit-style design shares internal parts with the Chelsea 442 Series, simplifying bench service. Call us to confirm proper fit for your specific transmission and application.
