The Chelsea 267XDKVW-M5AK or 267XDKVWM5AK is a 10-bolt constant mesh Power Take-Off engineered for Allison automatic transmissions. This 267 Series unit delivers up to 335 lb-ft (454 Nm) intermittent torque and produces 32 HP at 500 RPM, scaling to 64 HP at 1,000 RPM. The output shaft is a 1-1/4" round shaft with keyway. Continuous operation is supported with a 30% de-rating applied. The 267 Series exceeds the torque capacity of a 6-bolt PTO while offering the tighter sealing of a 10-bolt pattern, making it a practical fit for yard jockey trucks, small refuse trucks, and snow plow applications. Call us to confirm proper fit for your specific transmission and pump configuration.
The Chelsea 267 Series is compatible with variable displacement piston pumps and is used across aerial, refuse, snow and ice removal, military, and yard jockey truck applications. The 267 Series mounts on a 10-bolt pattern and is available in multiple output types and five speed ratios. The SuperTorque option provides up to 20% additional torque capacity compared to a standard 267 Series unit. Consult the 267 Series application pages to confirm the correct torque rating for your specific configuration.
