The Chelsea 267XMFJW-M5AF or 267XMFJWM5AF is a 10-bolt, constant mesh Power Take-Off assembly from the Chelsea 267 Series, designed for Allison automatic transmissions. The 1-1/4" round output shaft with keyway drives variable displacement piston pumps and other mobile hydraulic systems. Shaft power is rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM, with intermittent torque ranging from 301 to 400 lb-ft (check application pages for actual torque ratings). The 267 Series suits refuse trucks, snow and ice removal rigs, and yard jockey trucks where continuous load-sensing pump operation is required. Chelsea's 360-degree rotatable flange design helps with installation clearance in tight engine compartments. Call us to confirm proper fit for your specific transmission and application.
