The Chelsea 447 Series Power Take-Off Assembly, part number 447KWESX-W3XK or 447KWESXW3XK, is a 6-bolt mount PTO built for a wide range of vocational truck applications including dump trucks, utility trucks, and aerial and fire/rescue equipment. It uses a wire/cable mechanical shift and features a 1-1/4" round output shaft with keyway. The 447 Series uses a one-piece input gear with a gap between its two gear-tooth sets, a design that eliminates interference problems inside the PTO opening on transmissions that would otherwise cause fitment conflicts. Compatible with Eaton/Fuller, ZF, and other transmission manufacturers. Tapered bearings replace needle bearings for greater load capacity. Output reaches 43 HP at 1,000 RPM.
