Looking for the Daewoo Solar 420LC-V shop manual PDF? This 582-page factory shop manual covers the 2001 Solar track excavator line, and the hydraulic and electrical schematics in it are drawn for the 420LC-V specifically rather than as a generic family drawing. Coverage runs from the electrical schematics through hydraulic troubleshooting with pilot pressure and power mode valve testing, then into step-by-step rebuild procedures for the Rexroth main pump, Kayaba main control valve, swing motor, and Nabuko travel motor. Cylinders, center joint, and track assembly get their own service sections too. Set the 1/2-inch split flange bolts at 2.1 to 2.5 kg-m (15 to 18 ft lb) and snug the T-bolt hose clamps to 0.6-0.7 kg-m. Your excavator is down; get factory numbers, not forum guesses. Bookmarked with a full text layer, so you can jump to any valve section right from the phone in your cab.
