The Chelsea 282 Series Power Take-Off Assembly, part number 282GKAJX-P3RK or 282GKAJXP3RK, is a medium-duty hot-shift PTO built for demanding mobile equipment applications including aerial work platforms, towing and recovery, construction equipment, water trucks, and fuel oil delivery vehicles. The 8-bolt mounting configuration accepts pneumatic or PowerShift (pneumatic/hydraulic) actuation. The 1-1/4" round output shaft uses a 5/16" key and is driven through a range that delivers 29 HP at 500 RPM and 57 HP at 1,000 RPM. Continuous torque capability reaches 300 lb-ft, with intermittent torque rated at 201-300 lb-ft. Compatible with transmissions from Allison, Eaton/Fuller, Volvo/Mack, and other manufacturers. 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. Applications include aerial equipment, construction machinery, towing and recovery vehicles, water trucks, and home fuel oil delivery trucks. The series also serves defense and material handling markets. Rotatable flanges allow output orientation to be adjusted at installation. The Wet-Spline option (where specified) reduces wear on direct-mount pump shafts for longer service intervals. The Smart Start option manages engagement torque during high-load start-up conditions.
