The Chelsea 267SBKVP-M5AK or 267SBKVPM5AK is a 10-bolt, constant mesh Power Take-Off from Chelsea's 267 Series, engineered specifically for Allison automatic transmissions. It delivers up to 335 lb-ft (454 Nm) intermittent torque and 56+ HP output, making it a practical choice for variable-displacement piston pump applications such as refuse trucks, yard jockey trucks, and snow and ice removal equipment. The output shaft is a 1-1/4" round shaft with keyway. Shaft power ratings are 32 HP at 500 RPM and 64 HP at 1,000 RPM. The 267 Series exceeds the torque capacity of a comparable 6-bolt PTO while offering tighter sealing through its 10-bolt mounting pattern.
