The Chelsea 267 Series Power Take-Off, part number 267XMFJP-M3PA or 267XMFJPM3PA, is a 10-bolt constant-mesh PTO engineered to mount on Allison automatic transmissions. The 267 Series delivers intermittent torque in the 301-400 lb-ft range, with application-specific ratings up to 335 lb-ft (454 Nm) - confirm the exact value on the Chelsea application pages for your transmission. Output shaft is a 1-1/4" round with key. Shaft power is rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM, with output power exceeding 56 HP. The 267 Series is suited for variable-displacement piston pumps on refuse trucks, snow and ice equipment, yard jockey trucks, and aerial applications. Chelsea's 360-degree rotatable flange design aids clearance in tight installations. Call us to confirm proper fit for your transmission and pump configuration.
The Chelsea 267 Series fits refuse trucks, snow and ice removal vehicles, yard jockey trucks, and aerial equipment requiring a constant-mesh PTO on Allison automatic transmissions. The series is available with multiple output types including SAE B, SAE C, and ISO 7652 pump flanges in addition to driveline outputs. The SuperTorque option provides up to 20% more torque capacity than a standard 267 Series configuration. Wet spline lubrication is available to reduce wear on both the PTO and the connected pump shaft.
