The Chelsea 267SDFJW-M5AK or 267SDFJWM5AK is a 10-bolt, constant mesh Power Take-Off from the Chelsea 267 Series, engineered specifically for Allison automatic transmissions. It delivers an intermittent torque rating of 335 lb-ft (454 Nm) - check application pages for your exact rating - and shaft power of 32 HP at 500 RPM or 64 HP at 1,000 RPM. The 1-1/4" round output shaft includes a keyway. Chelsea's 360-degree rotatable flange design gives installers flexibility in tight mounting situations, and the wet spline option helps extend the service life of both PTO and pump shaft. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks. Call us to confirm proper fit for your specific transmission and pump configuration.
The 267 Series is available in five speed ratios and multiple output configurations. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series unit. Continuous operation is supported with a 30% de-rating applied. Common markets include refuse, snow and ice removal, aerial, and military applications.
