Hydraulic power unit used with OSE equipment. Latest cut. This one includes the bolts for the structural frame and another to add bolts for the cooler assembly and to fix some plumbing details. In this version, I’ve added a breakout of modules for pre-assembly organization. Added solenoid and mounting bracket. Added NPT threaded ends to hoses. Grouped modules more completely. Added assembled module views. Changed suction plumbing for stacking power cubes. Added missing bolts to frame module. Fixed orientation and hole sizes of pump / engine plates. Changed control bracket mounting. Re-worked oil cooler, more to do there. Re-sized vertical oil cooler tubes - better now. Addd detailed hardware for oil cooler mounting. Updated the bracket in the Pressure Plumbing for proper holes for pressure relief valve. Updated Hydraulic Reservoir - moved sight gauge 4” from suction port to abate heat problems during fabrication. Updated Hydraulic Reservoir - Switched suction port from plumbing union to 2” flange and added bushing to reduce to 1 1/2” for suction strainer. Also updated pressure plumbing with proper hole spacing on pressure relief valve and bracket.
