The Chelsea 282GSAJX-V3RK or 282GSAJXV3RK is an 8-bolt, medium-duty hot-shift power take-off from the Chelsea 282 Series, compatible with Allison, Eaton/Fuller, Volvo/Mack, and a range of other transmissions. It ships with a 1-1/4" round output shaft keyed with a 5/16" key, and supports both pneumatic and PowerShift (pneumatic/hydraulic) actuation. The 282 Series carries a continuous-duty torque capability up to 300 lb-ft (407 Nm) and intermittent ratings in the 201-300 lb-ft (401-500 Nm) range. Shaft power output reaches 57 HP at 1,000 RPM. Common applications within this series include aerial, towing and recovery, construction equipment, water trucks, and fuel oil delivery. Call us to confirm proper fit for your application.

The Chelsea 282 Series consolidates nine speed ratios and eighteen shift options into a single medium-duty platform. Direct-mount outputs are available with the optional Wet-Spline configuration to extend PTO and pump shaft service life. Driveshaft outputs include a positive stop that guards against seal damage from driveshaft yokes. This series is suited for aerial, construction equipment, towing and recovery, water truck, and home fuel oil delivery applications. The optional Smart Start feature manages high-torque engagement, reducing stress during start-up. The 282GSAJX-V3RK is also referenced as SP282GSAJX-V3RK in some catalog systems.
