The Chelsea 447 Series Power Take-Off Assembly, part number 447KWESX-A3RA or 447KWESXA3RA, is a 6-bolt PTO built around a one-piece input gear with a gap between its two sets of gear teeth. That design eliminates interference problems inside the transmission PTO opening, a common fitment challenge on a wide variety of transmissions including Eaton/Fuller and ZF units. Shift is wire/cable or mechanical. The 1-1/4" round output shaft accommodates a keyed connection. Output power spans 36-45 HP (31-40 kW), with shaft power rated at 21 HP at 500 RPM and 43 HP at 1,000 RPM. Intermittent torque runs 201-300 lb-ft; check application pages for actual torque ratings on your specific installation. No adapter plate is required for most applications. Call us to confirm proper fit for your truck and transmission.
