The Chelsea 267 Series Power Take-Off, part number 267XSFJP-M5TV or 267XSFJPM5TV, is a 10-bolt constant mesh PTO designed for Allison and compatible automatic transmissions. Developed in cooperation with Allison engineers specifically for their World Transmissions, the 267 Series delivers intermittent torque in the 301-400 lb-ft range and shaft power of 32 HP at 500 RPM or 64 HP at 1000 RPM. The output shaft is a 1-1/4" round shaft with key. Chelsea's 360-degree rotatable flange option improves installation clearance, and the SuperTorque gear option adds up to 20% more torque capacity over a standard unit. Wet spline or greaseable shaft configurations help extend PTO and pump shaft service life. This unit suits variable displacement piston pump applications on refuse trucks, snow and ice removal equipment, yard jockey trucks, and aerial platforms. Call us to confirm proper fit for your specific transmission and pump configuration.
The Chelsea 267 Series is available with five speed ratios and multiple output configurations. Compatible output flange types within the 267 Series family include SAE B, SAE C, and ISO 7652 pump flanges, as well as driveline outputs. The series supports continuous operation with a 30% de-rating. Common applications include snow plow trucks, small refuse trucks, and yard jockey trucks. The 267 Series exceeds the torque capacity of a 6-bolt PTO while providing the tighter sealing associated with the 10-bolt bolt pattern. For application-specific torque ratings and speed ratio availability, check the Chelsea 267 Series application pages or call Pro Gear and Transmission to confirm the right configuration for your truck and pump.
