The Chelsea 447KWESX-S3XK or 447KWESXS3XK is a 6-bolt Power Take-Off assembly from the Chelsea 447 Series, engineered with a one-piece input gear that spaces the two sets of gear teeth apart to eliminate interference inside the transmission PTO opening. It shifts via wire/cable mechanical actuation and delivers up to 43 HP (32 kW) at 1,000 RPM, with an intermittent torque rating in the 201-300 lb-ft range (check application pages for actual torque ratings). The output shaft is a 1-1/4" round configuration, with a keyed variant also available in the series. Strong tapered bearings replace the needle bearings found on earlier designs for improved load capacity. Compatible with Eaton/Fuller, ZF, and a range of other transmission manufacturers. Call us to confirm proper fit for your application.
