The Chelsea 282GMAJX-V3RK or 282GMAJXV3RK is a medium-duty hot-shift power take-off from the Chelsea 282 Series, designed for demanding continuous-duty applications. This 8-bolt unit supports both pneumatic and PowerShift (pneumatic/hydraulic) engagement and carries a continuous torque rating up to 300 lb-ft (407 Nm) with an intermittent range of 201-300 lb-ft (401-500 Nm). The 1-1/4" round output shaft accepts a 5/16" key. Shaft power output is rated at 29 HP (21 kW) at 500 RPM and 57 HP (43 kW) at 1,000 RPM. Compatible transmission manufacturers include Allison, Volvo/Mack, Eaton/Fuller, and others. Common applications include aerial trucks, towing and recovery, construction equipment, water trucks, and fuel oil delivery. Call us to confirm proper fit for your transmission and application.
The 282GMAJX-V3RK is part of the Chelsea 282 Series, a redesigned medium-duty hot-shift PTO line that consolidates the best elements of the 238 Series into a single versatile platform. The 282 Series offers nine speed ratios and eighteen shift options, giving fleet and equipment managers flexibility across a wide range of direct-mount and driveshaft output configurations. Direct-mount setups are available with optional Wet-Spline technology to extend PTO and pump shaft service life. Driveshaft output versions include a positive stop to prevent seal damage from driveshaft yoke contact. The Smart Start option helps manage high-torque engagement at startup. Typical markets for this series include aerial, construction equipment, towing and recovery, water trucks, home fuel oil delivery, material handling, and defense applications.
