The Chelsea 267SGFJP-M5XK or 267SGFJPM5XK is a 267 Series Power Take-Off assembly built on a 10-bolt mounting pattern for Allison automatic transmissions. This constant mesh PTO delivers intermittent torque in the 301-400 lb-ft range, with shaft power rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM. Output is through a 1-1/4" round shaft with key. The 267 Series is engineered for variable-displacement piston pumps and continuous-duty mobile applications including refuse trucks, snow and ice removal vehicles, and yard jockey trucks. Chelsea's 360-degree rotatable flange design simplifies installation clearance, and the SuperTorque gear option adds up to 20% more torque capacity over a standard 267 Series unit. Call us to confirm proper fit for your specific transmission and pump configuration.
The Chelsea 267 Series is available with multiple output flange types including SAE B, SAE C, and ISO 7652 pump flanges, as well as driveline outputs. Common applications include small refuse trucks, snow plow trucks, and yard jockey trucks requiring consistent hydraulic power for load-sensing systems. The 267 Series exceeds the torque capacity of a standard 6-bolt PTO while offering the tighter sealing of a 10-bolt pattern. Contact Pro Gear and Transmission to confirm the correct speed ratio and output configuration for your pump and vehicle setup.
