The Chelsea 267SDKVP-M5XD or 267SDKVPM5XD is a 10-bolt, constant mesh Power Take-Off from the Chelsea 267 Series, engineered to fit Allison automatic transmissions. The output shaft is a 1-1/4" round with keyway. Intermittent torque capacity runs 301-400 lb-ft (401-500 Nm), with a series rating up to 335 lb-ft (454 Nm), verify actual torque against the application pages for your specific configuration. Output power exceeds 56 HP, with shaft power of 32 HP at 500 RPM and 64 HP at 1,000 RPM. The 267 Series is a non-shiftable, constant mesh design suited for mobile applications running load-sensing and variable displacement piston pumps, including refuse trucks, snow and ice vehicles, and yard jockey trucks. Call us to confirm proper fit for your application.
The Chelsea 267 Series fits Allison and CAT automatic transmissions and is available in five speed ratios. Output flange options within the series include SAE B, SAE C, and ISO 7652 pump flanges, as well as driveline configurations. Chelsea's 360-degree rotatable flange option helps clear tight mounting locations. The SuperTorque option delivers up to 20% more torque capacity compared to a standard 267 Series unit. Wet spline or greaseable shaft options extend service life of both the PTO and the connected pump shaft. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks.
