The Chelsea 447 Series Power Take-Off, part number 447KWESX-A3AF or 447KWESXA3AF, is a 6-bolt mounted PTO designed around a one-piece input gear with a space between the two sets of gear teeth. That geometry eliminates interference problems inside the transmission PTO opening, a common fitment headache on a wide range of transmissions including Eaton/Fuller and ZF units. Shift is wire/cable mechanical. The output shaft is a 1-1/4" round, also available with a key. Shaft power is rated at 21 HP at 500 RPM and 43 HP at 1,000 RPM; intermittent torque ranges from 201 to 300 lb-ft (check application pages for your specific rating). Typical applications include utility trucks, dump trucks, aerial equipment, and snow and ice removal vehicles. Call us to confirm proper fit for your transmission.
