Additional Information
The Chelsea 272 Series replaces and consolidates the earlier 230, 231, 236, 238, 270, and 271 Series PTOs into a single medium-duty hot shift platform. The series offers nine speed ratios and eighteen shift configurations, covering a wide range of transmission and application requirements. Typical markets include aerial work platforms, construction equipment, towing and recovery, water trucks, and material handling. The Smart Start option is available for applications requiring high-torque engagement at start-up. Wet-Spline technology on direct-mount outputs reduces wear on the PTO output shaft and mating pump shaft, extending service intervals in demanding duty cycles.Parts manual and diagrams: Chelsea 272 Series PTO parts list with prices
