The Chelsea 489 Series Power Take-Off, part number 489XRITX-V3XK or 489XRITXV3XK, is an 8-bolt PTO assembly designed for manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. Output shaft is a 1-1/4" round shaft with key. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); continuous-duty applications should de-rate 30% (verify actual ratings on the Chelsea application pages). Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common with the Chelsea 442 Series. Call us to confirm proper fit for your transmission and application.
