An output shaft of a hydraulic motor is enclosed within a sealed housing and coupled to an input shaft of an electric generator using non-contact couplings. Tool electrical components are electrically coupled to the electric generator. A high pressure hydraulic tool circuit includes a hydraulic tool load and the hydraulic motor of the electric power generation assembly coupleable between a hydraulic boom inlet line and a hydraulic boom return line. Both the hydraulic tool load and the hydraulic motor of the electric power generation assembly can be designed to input hydraulic fluid up to the full rated pressure of the tool. The sealed housing of the hydraulic motor of the electric power generation assembly can be designed to retain hydraulic fluid within the interior up to the full rated pressure of the tool so that no case drain or separate low pressure return line for the hydraulic motor is necessary.
