The Chelsea 267XBFJP-M5XX or 267XBFJPM5XX is a constant-mesh power take-off from the 267 Series, built on a 10-bolt mounting pattern for Allison automatic transmissions. The output shaft is a 1-1/4" round shaft with key. Intermittent torque capacity falls in the 301-400 lb-ft range, with application-specific ratings up to 335 lb-ft (454 Nm) - check the application pages for your confirmed torque figure. 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 a proven fit for refuse trucks, snow and ice equipment, yard jockeys, and aerial units. The 360-degree rotatable flange aids clearance in tight installs. Call us to confirm proper fit for your specific transmission and chassis.
The Chelsea 267 Series is compatible with variable displacement piston pumps and is used in refuse collection, snow and ice removal, yard jockey, aerial, and military applications. The 267 Series exceeds the torque capacity of a standard 6-bolt PTO while providing the tighter sealing of a 10-bolt pattern. Five speed ratios are available across the series. Cross-references for this part include 1450-267XBFJPM5XX and 1450267XBFJPM5XX.
