Chelsea PTO Assembly 267XCKVP-M3RA or 267XCKVPM3RA is a 10-bolt constant mesh power take-off from the Chelsea 267 Series, designed to mount on Allison automatic transmissions. It delivers up to 335 lb-ft (454 Nm) intermittent torque and 64 HP shaft power at 1,000 RPM, stepping down to 32 HP at 500 RPM. The output shaft is a 1-1/4" round with keyway. The 267 Series operates continuously with a 30% de-rating and suits load-sensing hydraulic pump applications such as refuse trucks, snow and ice removal, and yard jockey trucks. A 360-degree rotatable output flange aids installation clearance. A genuine Chelsea part from Pro Gear and Transmission. Call us to confirm proper fit for your application.
The Chelsea 267 Series is available in multiple output configurations including SAE B, SAE C, and ISO 7652 pump flanges, as well as driveline outputs. Output shaft options across the series include SAE B (7/8"-13T), SAE C (1-1/4"-14T), SAE A (5/8"-9T), SAE BB (1"-15T), DIN 5462, and 3/4"-11T pump splines, in addition to the 1-1/4" round keyed shaft on this assembly. The 267 Series is co-developed with Allison engineers for direct fitment on Allison World Transmissions. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks requiring continuous power to variable displacement piston pumps.
