The Chelsea 267 Series Power Take-Off Assembly, part number 267XBFJP-M5GH or 267XBFJPM5GH, is a 10-bolt constant mesh PTO engineered for Allison automatic transmissions. The 267 Series exceeds the torque capacity of a 6-bolt PTO while delivering the tighter sealing of a 10-bolt mounting pattern. This unit features a 1-1/4" round output shaft with key and delivers up to 64 HP at 1,000 RPM shaft power, with intermittent torque ratings up to 335 lb-ft (check application pages for actual torque ratings). The 267 Series suits variable displacement piston pump applications including refuse trucks, snow and ice removal, and yard jockey trucks. Rotatable flanges allow clearance adjustments on tight installations. Call us to confirm proper fit for your specific transmission and pump configuration.
