Description
The Chelsea 489 Series Power Take-Off Assembly, part number 489XHAHX-W3XK or 489XHAHXW3XK, is an 8-bolt PTO built for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and its potential leak path. Intermittent torque capacity matches the 442 Series at 250 lb-ft (339 Nm); check application pages for your actual rating. The output shaft is a 1-1/4″ round with key. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Shift is accomplished via wire/cable mechanical actuation. Internal parts are common to the Chelsea 442 Series, simplifying parts sourcing and service. Call us to confirm proper fit for your transmission.
