The Chelsea 489 Series Power Take-Off Assembly, part number 489ZHDAX-H6XD or 489ZHDAXH6XD, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, removing a potential leak path compared to designs that require one. This unit uses tapered bearings rather than needle bearings for greater load-bearing capability. The 489 Series delivers intermittent torque consistent with the 442 Series at 250 lb-ft, with wire/cable mechanical shift and a 1-1/4" round output shaft. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, simplifying parts sourcing and service. Fits vocational applications including utility trucks, dump trucks, snow and ice removal, and fire and rescue equipment. Call us to confirm proper fit for your transmission.
