The Chelsea 489 Series Power Take-Off 489ZFITX-P5XK or 489ZFITXP5XK 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. This unit uses a wire/cable mechanical shift and delivers 24 HP at 500 RPM and 48 HP at 1,000 RPM. Output is through a 1-1/4" round shaft with key. The P5XK designation confirms pressure lubrication. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm), the same rating as the Chelsea 442 Series. Internal parts are common to the 442 Series, and the assembly is designed for field servicing as a kit-style unit. Call us to confirm proper fit for your specific transmission.
