The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-A3GQ or 489XFAHXA3GQ, is a one-piece cast iron 8-bolt PTO designed to mount directly to compatible manual transmissions from Eaton/Fuller, Volvo/Mack, and other manufacturers without an adapter plate, eliminating a potential leak path. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and produces 46-55 HP output power. Shaft power measures 24 HP at 500 RPM and 48 HP at 1,000 RPM. The output shaft is a 1-1/4" round configuration with key. Shift is accomplished via wire/cable mechanical mechanism. Strong tapered bearings replace needle bearings for greater load-bearing capability. A genuine Chelsea part, available from Pro Gear and Transmission.
