Need the factory procedures for your Daewoo Solar 140LC-V hydraulic excavator? This 636-page Daewoo Solar 140LC-V Shop Manual PDF (OEM #023-00076E) covers the machine from swing bearing to track assembly. Inside: a full hydraulic schematic, electrical schematics for tracing wiring faults, and step-by-step teardown and reassembly procedures for the main pump, swing motor, travel motor, and main control valve. You also get cylinder rebuild instructions and a standard torque section covering metric fasteners from 0.15 to 103.00 kg-m. Set the motor makeup valve gauge pressure to 10 bar (145 psi), and torque hydraulic hose clamps to 0.5-0.6 kg-m, straight from the factory tables. No more chasing hydraulic pressure problems with borrowed numbers. Bookmarked with a full text layer; search any spec by keyword, pull it up on your phone, and get back to work.
