Every one of the 426 pages in this Daewoo Solar 75-V shop manual PDF (OEM 023-00066AE) goes toward one goal: putting your 75-V track excavator back to factory spec. Inside: a full hydraulic schematic with standard and option circuits, a complete electrical schematic, and step-by-step rebuild procedures for the Rexroth main pump, travel motor, swing motor, cylinders, and main control valve. You also get standard torque tables, troubleshooting charts for every hydraulic component, and full track assembly and swing bearing service. Fill the hydraulic system to 150 liters (93 in the reservoir), and pull grade 8.8 M8 bolts to 21 Nm. Your excavator is down; forum guesses won't lift it. Bookmarked and text-searchable: type the spec, land on the page, start wrenching.
