The Chelsea 267XMFJW-M5RY or 267XMFJWM5RY is a 267 Series constant mesh power take-off built on a 10-bolt mounting pattern for Allison automatic transmissions. This series delivers up to 335 lb-ft (454 Nm) intermittent torque and shaft power of 32 HP at 500 RPM, scaling to 64 HP at 1,000 RPM. The output shaft is a 1-1/4" round with keyway configuration. Chelsea's 267 Series was co-developed with Allison engineers specifically for Allison World Transmissions, making it a common choice for yard jockey trucks, small refuse trucks, and snow and ice removal equipment running variable displacement piston pumps. The 360-degree rotatable flange eases clearance in tight installations. Call us to confirm proper fit for your transmission and pump configuration.
