The Chelsea 267SDFJP-M5GF or 267SDFJPM5GF is a 267 Series constant mesh power take-off built on a 10-bolt mounting pattern for Allison automatic transmissions. The 267 Series exceeds the torque capacity of a 6-bolt PTO while maintaining the tighter sealing of the 10-bolt pattern, with intermittent torque ratings in the 301-400 lb-ft range (check application pages for actual torque ratings on your installation). Output shaft is a 1-1/4" round with key. Shaft power is rated at 32 HP at 500 RPM and 64 HP at 1000 RPM. Chelsea's 360-degree rotatable output flange helps clear tight pump installations. Suited for yard jockey trucks, small refuse trucks, and snow and ice removal equipment. Call us to confirm proper fit for your transmission and pump configuration.
The Chelsea 267 Series is designed for mobile applications requiring continuous power delivery to load-sensing pumps. Common applications include yard jockey trucks, small refuse trucks, and snow and ice removal vehicles. The 267 Series is available in five speed ratios and multiple output types. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit. Wet spline and greaseable shaft configurations are available to reduce wear at the PTO-to-pump interface. The 360-degree rotatable flange gives installers flexibility when pump placement is tight. For application-specific torque ratings, consult the Chelsea 267 Series application pages or call Pro Gear and Transmission.
