The Chelsea 267 Series Power Take-Off, part number 267XBFJW-M5XK or 267XBFJWM5XK, is a 10-bolt constant mesh PTO engineered to fit Allison automatic transmissions. It delivers intermittent torque in the 301-400 lb-ft range, with application-specific ratings up to 335 lb-ft (454 Nm) -- verify the exact figure on Chelsea's application pages for your setup. The 1-1/4" round output shaft with keyway suits hydraulic pump drives on yard jockey trucks, small refuse trucks, and snow and ice removal equipment. Shaft power runs 32 HP at 500 RPM and 64 HP at 1,000 RPM, with output exceeding 56 HP total. The 267 Series uses a non-shiftable constant mesh design, making it well-suited for load-sensing pump applications that require continuous power. Call us to confirm proper fit for your transmission and pump configuration.
The Chelsea 267 Series is available in five speed ratios and multiple output configurations, including the 360-degree rotatable flange. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series build. Wet spline and greaseable shaft options are available to extend service intervals for both the PTO and the driven pump. Typical applications include snow plow trucks, small refuse trucks, and yard jockey trucks. Contact Pro Gear and Transmission to confirm the correct ratio and output configuration for your specific pump and vehicle.
