Additional Information
The Chelsea 282 Series was developed as a redesign of the medium-duty hot shift PTO lineup, combining proven components into a single versatile platform. The series offers nine speed ratios, eighteen shift configurations, and a choice of direct-mount or driveshaft output options. Direct-mount configurations are available with optional Wet-Spline technology, which extends service life on both the PTO and pump shaft. Driveshaft output versions include a positive stop feature designed to prevent seal damage from driveshaft yokes. The integral air valve and rotatable flanges simplify installation across different truck chassis. The 282 Series is well established in fuel oil delivery, towing and recovery, aerial lift, construction equipment, and water truck markets.
