The Chelsea 447 Series Power Take-Off Assembly, part number 447KSESX-H3XD or 447KSESXH3XD, is a 6-bolt mounted PTO designed to eliminate interference problems inside the transmission PTO opening. It uses a one-piece input gear with a space between the two gear-tooth sets, which solves adjacent gear interference on a wide range of transmissions including Eaton/Fuller, ZF, and other compatible units. The output shaft is a 1-1/4" round with key, and the unit accepts wire/cable or mechanical shift. Intermittent torque rating for the 447 Series runs 201-300 lb-ft (check application pages for your actual rating), with shaft power of 21 HP at 500 RPM and 43 HP at 1000 RPM. Common applications include dump trucks, utility trucks, aerial equipment, and snow and ice removal vehicles. Call us to confirm proper fit for your specific transmission and chassis.
