The Chelsea 282 Series Power Take-Off Assembly, part number 282XGAJX-15RF or 282XGAJX15RF, is a medium-duty hot-shift PTO built for continuous-duty cycles. Mounting is via an 8-bolt pattern, and it accepts pneumatic or PowerShift (pneumatic/hydraulic) actuation with an integral air valve. The 1-1/4" round output shaft uses a 5/16" key. Shaft power output is rated at 29 HP at 500 RPM and 57 HP at 1,000 RPM. This assembly is compatible with Allison, Eaton/Fuller, Volvo/Mack, and other transmission platforms. Typical applications include aerial, construction equipment, towing and recovery, water trucks, and fuel oil delivery. Call us to confirm proper fit for your specific transmission and application.
The 282 Series combines nine speed ratios and 18 shift options in a single medium-duty hot-shift PTO platform. Rotatable flanges allow flexible installation orientation. The Wet-Spline option (where specified in the part number) lubricates the direct-mount interface to extend pump shaft service life. The positive stop on driveshaft outputs prevents seal damage from yoke over-insertion. Common markets include aerial lift, construction equipment, towing and recovery, water trucks, fuel oil delivery, and defense/other mobile applications.
