The Chelsea 267SDFJW-M3RY or 267SDFJWM3RY is a 267 Series constant mesh power take-off built on a 10-bolt mounting pattern for Allison automatic transmissions. The output shaft is a 1-1/4" round shaft with keyway. Intermittent torque rating for the 267 Series runs up to 335 lb-ft (454 Nm) - check application pages to confirm the actual rating for your specific setup. Shaft power is 32 HP at 500 RPM and 64 HP at 1,000 RPM, with output power exceeding 56 HP. The 267 Series suits variable-displacement piston pump applications including refuse trucks, snow and ice equipment, yard jockey trucks, and aerial units. Chelsea's 360-degree rotatable flange aids clearance in tight installations. 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. Output options across the 267 Series family include SAE B, SAE C, and ISO 7652 pump flanges, as well as driveline outputs. The SuperTorque option and wet spline shaft are factory-selectable configurations that affect application suitability - confirm which options are included in part number 267SDFJW-M3RY when ordering. Common applications include snow plow trucks, small refuse trucks, and yard jockey trucks.
