The Chelsea 489 Series Power Take-Off Assembly, part number 489XQAHX-P3RF or 489XQAHXP3RF, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec units. The one-piece cast iron housing eliminates the need for an adapter plate, cutting potential leak paths. The 489 Series is rated for 201-300 lb-ft intermittent torque and delivers up to 48 HP at 1,000 RPM through a 1-1/4" round output shaft. This configuration uses wire/cable mechanical shift and pressure lubrication (P designation). Tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are common to the Chelsea 442 Series, simplifying service inventory. Sold by Pro Gear and Transmission. Call us to confirm proper fit for your application.
