A kit adapted for converting a manual jack assembly to power drill drive includes a power drill drive unit, including (a) a first drive shaft adapted for connecting the power drill drive unit to an original output gear of the manual jack assembly, (b) a second drive shaft including a torque limiter, and (c) a gear reduction section connecting the second drive shaft to the first drive shaft. The kit is useful in a method of converting a manual jack assembly to power drill drive. The method includes removing an original output gear of the manual jack assembly from an original drive shaft of the manual jack assembly, replacing the original drive shaft of the manual jack assembly with a first drive shaft adapted to connect a power drill drive unit to the manual jack assembly, and connecting the first drive shaft to the original output gear.
