The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-T5SQ or 489XLAHXT5SQ, mounts directly to an 8-bolt transmission opening on compatible Eaton Fuller, Mack, and Tremec manual transmissions. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths. Shift type is air shift, with an electric-over-air shift option also available in the series. Output is through an SAE B 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); continuous torque is de-rated 30% from that figure. Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
