The Chelsea 267 Series Power Take-Off, part number 267XBKVP-M5RF or 267XBKVPM5RF, is a 10-bolt constant mesh PTO engineered to mount on Allison automatic transmissions. It delivers an intermittent torque rating in the 301-400 lb-ft range, with 335 lb-ft cited for this series (verify actual rating against Chelsea application pages for your specific installation). The 1-1/4" round output shaft includes a keyway. Shaft power output is 32 HP at 500 RPM and 64 HP at 1,000 RPM, with an output power rating of 56+ HP. The 267 Series is well suited for load-sensing hydraulic pump applications such as yard jockey trucks, small refuse trucks, and snow and ice vehicles. Call us to confirm proper fit for your transmission and pump configuration.
The Chelsea 267 Series is designed to exceed the torque capacity of a 6-bolt PTO while providing the tighter sealing of a 10-bolt pattern. It is available in five speed ratios and multiple output types. The 267 Series supports continuous operation with a 30% de-rating. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks. Common markets include aerial, refuse, military, and snow and ice removal operations.
