The Chelsea 447 Series Power Take-Off Assembly, part number 447XUITX-H3XD or 447XUITXH3XD, is a 6-bolt mounted PTO designed to eliminate internal interference problems across a wide variety of transmissions, including Eaton/Fuller and ZF applications. The 447 Series uses a one-piece input gear with a space between the two sets of gear teeth specifically to clear adjacent gear interference inside the transmission PTO aperture. Output shaft is a 1-1/4" round shaft with keyway. No shift assembly (ordered without a shifter). Intermittent torque rating runs 201-300 lb-ft (301-400 Nm), with actual ratings varying by application. Shaft power is rated at 21 HP at 500 RPM and 43 HP at 1000 RPM. For continuous-duty use, apply a 30% torque de-rate per Chelsea application guidelines. Call us to confirm proper fit for your specific transmission and application.
