The Chelsea 267XDFJP-M5AK is a 267 Series constant mesh power take-off assembly built on a 10-bolt mounting pattern for Allison automatic transmissions. This non-shiftable PTO delivers up to 335 lb-ft (454 Nm) intermittent torque and is rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM, with output exceeding 56 HP total. The 1-1/4" round output shaft ships with a keyway. The 267 Series exceeds the torque capacity of a 6-bolt design while offering the tighter sealing of a 10-bolt pattern, making it a practical choice for variable displacement piston pump circuits on yard jockey trucks, snow and ice vehicles, and small refuse units. Rotatable flanges allow clearance adjustments without relocating the PTO. Call us to confirm proper fit for your application.
