The Chelsea 447 Series Power Take-Off Assembly, part number 447XUESX-A5XD or 447XUESXA5XD, is a 6-bolt mounted PTO designed to eliminate internal interference problems on a wide variety of transmissions, including Eaton/Fuller and ZF applications. It uses a one-piece input gear with a gap between the two gear-tooth sets, which clears interference at the PTO aperture without requiring an adapter plate. Shift is accomplished via wire/cable or mechanical actuation. The 1-1/4" round output shaft (with key) delivers up to 43 HP at 1,000 RPM. Intermittent torque ratings fall in the 201-300 lb-ft range; check Chelsea application pages for confirmed torque values for your specific unit. Strong tapered bearings replace needle bearings for greater load-bearing capability across aerial, vocational, dump truck, and municipal equipment applications. Call us to confirm proper fit for your transmission.
