The Chelsea 282XMAJX-V3XR or 282XMAJXV3XR is an 8-bolt power take-off assembly from the Chelsea 282 Series, engineered for medium-duty hot-shift applications. It mounts to transmissions from Allison, Eaton/Fuller, Volvo/Mack, and other manufacturers. The output shaft is a 1-1/4" round shaft with a 5/16" key. Shift is pneumatic or PowerShift (pneumatic/hydraulic), with an integral air valve built into the unit. The 282 Series carries a continuous-duty torque rating up to 300 lb-ft (407 Nm), with intermittent torque rated at 201-300 lb-ft (401-500 Nm). Shaft power at 1,000 RPM reaches 57 HP (43 kW). Rotatable flanges and an optional wet-spline drive add installation flexibility and extended service life. Call us to confirm proper fit for your specific transmission and application.
The 282XMAJX-V3XR is part of Chelsea's 282 Series, a redesigned medium-duty hot-shift platform that combines the 238 Series with upgraded components. The series offers nine speed ratios and eighteen shift options. Typical applications include aerial equipment, construction machinery, towing and recovery vehicles, water trucks, and fuel oil delivery trucks. The direct-mount outputs support an optional wet-spline configuration to extend PTO and pump shaft service life; driveshaft outputs include a positive stop to prevent seal damage from driveshaft yokes. The Smart Start option manages engagement torque for high-torque start-up situations.
