The Chelsea 267SMFJP-M3XY is a 267 Series Power Take-Off built on a 10-bolt mounting pattern for Allison automatic transmissions. This is a constant mesh, non-shiftable PTO suited for continuous-duty mobile applications, including yard jockey trucks, snow plow trucks, and small refuse trucks where load-sensing pumps run at steady output. The 267 Series exceeds the torque capacity of a 6-bolt PTO while delivering the tighter sealing of a 10-bolt pattern. Intermittent torque rating for the series runs 335 lb-ft (454 Nm), with continuous operation available at a 30% de-rating. Shaft power is rated at 32 HP at 500 RPM and 64 HP at 1,000 RPM. A genuine Chelsea part, available from Pro Gear and Transmission.
