Additional Information
The Chelsea 282 Series was developed as a redesign of the medium-duty hot shift PTO line, combining the strengths of the earlier 238 Series with updated components. The series includes optional Wet-Spline technology on direct-mount configurations for extended PTO and pump shaft service life, and driveshaft output variants feature a positive stop to help prevent seal damage from driveshaft yokes. A Smart Start option is available within the series for high-torque start-up conditions. Common vocational markets for this series include aerial lift trucks, construction equipment, towing and recovery vehicles, water trucks, and home fuel oil delivery trucks.
