The Chelsea 810 Series Power Take-Off Assembly, part number 810FSMFP-B2RK or 810FSMFPB2RK, is purpose-built for the Ford 10R140HD transmission. It mounts via an 8-bolt pattern and uses hydraulic shift engagement. The 810 Series spans a ratio range of 81% to 158% of engine speed across multiple output options, including a 1410 Series companion flange, a standard round shaft (1-1/4" with 5/16" key), an SAE B shaft (7/8"-13T), and an SAE BB shaft (1"-15T). Chelsea's Smart Start technology minimizes torque spike at engagement, while QuietGear technology smooths torsional vibrations for quieter operation in diesel applications.
