The Chelsea 267SMFJP-M5RF or 267SMFJPM5RF is a 10-bolt, constant mesh Power Take-Off from the Chelsea 267 Series, engineered specifically for Allison automatic transmissions. The output shaft is a 1-1/4" round with keyway, and the unit delivers shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM, with intermittent torque rated at 335 lb-ft (454 Nm), confirm actual ratings against the Chelsea application pages for your specific installation. The 267 Series exceeds the torque capacity of a 6-bolt PTO while maintaining the tighter sealing of a 10-bolt mounting pattern, making it a practical choice for refuse, snow and ice, and yard jockey truck applications. Call us to confirm proper fit for your transmission and pump configuration.
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. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks. Markets served include aerial, military, refuse, and snow and ice removal.
