The Chelsea 267XBKVW-M3AK or 267XBKVWM3AK is a 267 Series Power Take-Off built on a 10-bolt mounting pattern for Allison automatic transmissions. It operates as a constant mesh PTO, making it a practical choice for mobile applications that demand continuous power delivery to load-sensing hydraulic pumps. The output shaft is a 1-1/4" round shaft with keyway. Intermittent torque capacity for this series ranges from 301 to 400 lb-ft (401 to 500 Nm), with shaft power rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM. The 267 Series 10-bolt pattern provides tighter sealing than a 6-bolt design. Common applications in this series include yard jockey trucks, small refuse trucks, and snow and ice removal equipment. Call us to confirm proper fit for your application.
The Chelsea 267 Series is available in five speed ratios and multiple output configurations, including a 360-degree rotatable flange. The SuperTorque option provides up to 20% more torque capacity compared to a standard 267 Series unit. Series applications include snow plow trucks, small refuse trucks, and yard jockey trucks. The 267 Series also fits aerial and military equipment requiring continuous hydraulic power. Part number 267XBKVW-M3AK is also referenced as SP267XBKVW-M3AK in some catalog systems.
