The Chelsea 267XDFJW-M5RK is a 267 Series 10-bolt Power Take-Off engineered to mount on Allison automatic transmissions. The 267 Series operates as a constant mesh, non-shiftable PTO, making it well suited for continuous-duty mobile applications such as yard jockey trucks, small refuse trucks, and snow and ice equipment that demand steady power delivery to variable displacement piston pumps. The series supports multiple output types including SAE B, SAE C, and ISO 7652 pump flanges, with rotatable flange options to improve pump clearance during installation. Pressure lube and wet spline lubrication options help extend shaft life. The 10-bolt mounting pattern provides a tighter seal than a standard 6-bolt design while exceeding its torque capacity.
