The Chelsea 489 Series Power Take-Off Assembly, part number 489XCARX-M3XQ or 489XCARXM3XQ, mounts directly to an 8-bolt transmission opening on compatible Eaton/Fuller, Volvo/Mack, and other manual transmissions. The one-piece cast iron housing bolts on without an adapter plate, removing a potential leak path. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); shaft power output runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 7/8" 13-tooth SAE B shaft on an SAE B 2 or 4-bolt flange, rotated 90 degrees. Constant mesh (no shifter) is standard on this unit. Typical applications include utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles. Call us to confirm proper fit for your transmission and application.
