The Chelsea 489 Series Power Take-Off Assembly, part number 489XHAHX-V5XQ or 489XHAHXV5XQ, is an 8-bolt PTO built for most 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. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm); for continuous-duty applications, consult Chelsea application pages for the de-rated rating. This unit uses a wire/cable mechanical shift with a 1-1/4" round output shaft (with key), strong tapered bearings for greater load-bearing capability, and delivers 24 HP at 500 RPM and 48 HP at 1000 RPM. Internal parts are common to the Chelsea 442 Series, and greaseable output options are available. Call us to confirm proper fit for your transmission and application.
