The Chelsea 282XSAJX-A3XD or 282XSAJXA3XD is a medium-duty hot-shift Power Take-Off assembly from Parker Chelsea's 282 Series. This 8-bolt mount unit supports pneumatic or hydraulic (PowerShift) shift operation and is rated for intermittent torque of 201-300 lb-ft (401-500 Nm). Shaft power output reaches 57 HP at 1,000 RPM, making it a capable choice for aerial, towing and recovery, construction equipment, water truck, and fuel oil delivery applications. The 282 Series incorporates an integral air valve, rotatable flanges, and an optional Wet-Spline output for extended PTO and pump shaft service life. A positive stop on driveshaft outputs helps prevent seal damage from yoke over-travel. Call us to confirm proper fit for your application.

Additional Information
The Chelsea 282 Series was developed as a redesign of the medium-duty hot-shift PTO lineup, combining the 238 Series architecture with updated internal components. The result is a unit with nine available speed ratios, 18 shift configurations, and a broad selection of direct-mount and driveshaft output options. Direct-mount configurations are available with optional Wet-Spline technology to extend service life of the PTO and connected pump shaft. Driveshaft output versions include a positive stop feature that limits yoke travel and prevents seal damage. The 282 Series is suited for aerial work trucks, towing and recovery rigs, construction equipment, water trucks, and home fuel oil delivery vehicles.
