The Chelsea 489 Series Power Take-Off Assembly, part number 489XUITX-V3XY or 489XUITXV3XY, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec units. The one-piece cast iron housing eliminates the need for an adapter plate, reducing both installation time and potential leak paths. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); continuous torque is de-rated 30% from that figure (check application pages for actual ratings). Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key accepts a range of output configurations. Wire/cable mechanical shift is standard on this unit, with an electric-over-air shift option also available in the 489 Series. Internal components are common to the Chelsea 442 Series.
