The Chelsea 810 Series Power Take-Off Assembly, part number 810FMMFP-K2RF or 810FMMFPK2RF, is purpose-built for the Ford 10R140HD transmission. This 8-bolt, hydraulic-shift PTO runs on pressure lubrication and covers a ratio range of 81% to 158% of engine speed. Output options across the 810 Series include a 1410 Series companion flange, a standard round shaft with 1-1/4" bore and 5/16" key, an SAE B shaft at 7/8"-13T, and an SAE BB shaft at 1"-15T. The series carries a continuous torque rating of 195 to 420 lb-ft. Smart Start technology reduces torque spike at engagement, and Chelsea's QuietGear technology smooths torsional vibrations for quieter operation in diesel applications. Common applications include refuse, utility, dump, tow and recovery, fire and rescue, snow and ice, and service bodies. Call us to confirm proper fit and output configuration for your specific truck.
