267 Series

The Chelsea 267 Series PTO was developed in collaboration with Allison engineers for use with Allison World Transmissions, reflecting a shared focus on quality and performance. Designed as a versatile constant mesh PTO, the 267 Series delivers torque capacity that exceeds traditional 6-bolt PTO designs while incorporating the improved sealing benefits of a 10-bolt pattern. This makes it a strong choice for demanding applications such as refuse trucks and snow and ice removal equipment, where reliability under variable load conditions is critical. The 267 Series is available in five different speed ratios and a variety of output configurations, including Chelsea’s 360-degree rotatable flange for added installation flexibility. For higher-demand applications, the optional SuperTorque™ feature increases torque capacity by up to 20% over the standard 267 Series, further enhancing performance in heavy-duty environments.
