The Chelsea 267 Series Power Take-Off, part number 267XBKVP-M3AK or 267XBKVPM3AK, is a 10-bolt constant mesh PTO designed to fit Allison and CAT automatic transmissions. It delivers intermittent torque in the 301-400 lb-ft range and shaft power of 32 HP at 500 RPM and 64 HP at 1000 RPM. The output shaft is a 1-1/4" round shaft with key. The 10-bolt mounting pattern provides tighter sealing than a 6-bolt design, making this unit a practical choice for variable-displacement piston pump applications on refuse trucks, snow and ice removal equipment, and yard jockey trucks. The 360-degree rotatable flange aids installation clearance. Call us to confirm proper fit for your application.
