The Chelsea 267SGFJP-M5GF or 267SGFJPM5GF is a 267 Series Power Take-Off Assembly built for Allison automatic transmissions. Using a 10-bolt mounting pattern and constant mesh shift type, this PTO exceeds the torque capacity of a standard 6-bolt unit while delivering tighter sealing. Intermittent torque rating for the 267 Series ranges from 301 to 400 lb-ft (401 to 500 Nm), with a nominal figure of 335 lb-ft (454 Nm) subject to application-specific confirmation. The 1-1/4" round output shaft with key accepts common hydraulic pump configurations. Shaft power is rated at 32 HP at 500 RPM and 64 HP at 1000 RPM. Chelsea's 360-degree rotatable flange and wet spline shaft option make this a practical fit for refuse, snow and ice, and yard jockey truck applications. Call us to confirm proper fit for your specific transmission and pump setup.
