Abstract
The invention provides a hydraulic toe jack including a base adapted to be supported by the ground, an elongated piston extending from the base and defining an axis, a generally cylindrical toe housing having a closed end and an open end, the toe housing defining an inner surface surrounding a portion of the piston, the toe housing being movable along the axis relative to the piston, interengaging components on the inner surface and the piston for preventing rotation of the toe housing relative to the piston about the axis, and a seal sealingly fixed to the toe housing adjacent the open end of the toe housing and slidably sealingly engaged with the piston.
