The Chelsea 267XDFJP-M3RA or 267XDFJPM3RA is a 10-bolt constant mesh power take-off assembly from the Chelsea 267 Series, designed to fit Allison automatic transmissions. This non-shiftable PTO delivers an intermittent torque rating of 301-400 lb-ft (401-500 Nm), with shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, and output power exceeding 56 HP. The output shaft is a 1-1/4" round shaft with key. The 267 Series exceeds the torque capacity of a 6-bolt PTO while maintaining the tighter sealing of a 10-bolt pattern. The 360-degree rotatable flange design aids installation clearance, and wet spline or greaseable shaft options help extend service life. Common applications in this series include refuse trucks, snow and ice removal equipment, and yard jockey trucks. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 267 Series is available in five speed ratios and multiple output configurations, including SAE B pump flange, SAE C pump flange, ISO 7652 pump flange, and driveline outputs. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit. Continuous operation is supported with a 30% de-rating. Typical markets include aerial, refuse, snow and ice removal, and military applications.
