Looking for the Daewoo Solar 340LC-V shop manual PDF? This 597-page factory shop manual covers the 2001 Solar track excavator line, and the parts that matter most are cut for the 340LC-V specifically: the specifications section is headed "Specifications for Solar 340LC-V," and both schematic chapters carry the 340LC-V in their own titles instead of being shared across the family. Electrical schematics run complete. Hydraulic troubleshooting walks pilot pressure and power-mode valve testing. The Rexroth main pump, Kayaba main control valve, swing motor and travel motor with reduction gearbox each get a step-by-step rebuild, and so do the pilot control valve, travel control valve with damper, cylinders, center joint and track assembly. The machine runs a DE12TIS diesel rated at 250 ps at 1,900 rpm, ships at 33.9 metric tons, carries 550 liters of fuel and 460 liters in the whole hydraulic system, and wants main relief at 330 bar in Standard mode. Your excavator is down; get factory numbers, not forum guesses. Bookmarked with a full text layer, so you can jump straight to Hydraulics or Electrical System from the phone in your cab.

Daewoo Solar 340LC-V Common Problems This Manual Covers
Daewoo Solar 340LC-V boom and arm slow and weak, bucket loses power under load
Check hydraulic oil level and bleed air from the suction side before condemning the pump. Test main relief pressure with a cylinder stall in Standard mode; page 210 calls for at least 330 bar (4,785 psi) and under 335 bar, rising to 350 bar with "pressure up" selected. Then run the boom and arm circuit tests starting on page 195 and inspect cylinders for internal leakage past the piston seals.
Manual Section: Hydraulic System Troubleshooting, Testing and Adjustment p. 195Hydraulic oil temperature climbs into the red after an hour of steady digging
Clean the oil cooler fins with compressed air from the back side and verify oil level; the Solar 340LC-V system holds 460 liters, capacity listed on page 34. Check the return filter clogged-warning switch, which lights the panel when return filter pressure passes 1.5 kg/cm2 (21 psi, page 519); that warning means a plugged filter restricting return flow. Work the oil temperature chart from page 195.
Manual Section: Hydraulic System Troubleshooting, Testing and Adjustment p. 195Engine cranks slowly or will not turn over at all on cold mornings
Load-test both batteries before touching the starter; the system runs 150 AH batteries, spec on page 504. Clean and tighten the ground cables at the frame and starter mount. With the engine running, check alternator output; voltage held under 18 V for more than 3 seconds flags a charging fault. Replace corroded terminals, then retest cranking speed.
Manual Section: Electrical System p. 504Swing is jerky, drifts on slopes, or growls from the swing motor area
Bleed air from the swing circuit first, then check the swing relief valve: page 217 has you fit two 600 bar gauges at the swing motor ports and read 280 to 290 bar with both swing locks engaged. Inspect the anti-cavitation make-up valves and brake inside the swing motor, procedures beginning on page 258. If oil weeps at the swing center, pressure-test the center joint following the leakage test on page 230.
Manual Section: Hydraulics / Swing Motor p. 217Tracks throw off the idler on turns and shoes show uneven grouser wear
Measure grouser height on the standard 600 mm shoes: 26 mm (1.024 in) new, worn out at 13 mm (0.512 in), wear tables on page 140. Check front idler and roller dimensions against the same tables, reset track tension to spec, and replace stretched link assemblies before they start climbing the sprocket and derailing.
Manual Section: Lower Structure and Chassis p. 140Frequently Asked Questions
How do I reset an error code on a Daewoo Solar 340LC-V?
For codes like 01, 02, or 03, the reset procedure is to correct the problem and then turn the starter switch from "OFF" to "ON." For code 82, the system will automatically reset once the communication error between the e-EPOS controller and the instrument panel is corrected. p. 535
What are the hydraulic pressure test specifications for the main relief valve on the Solar 340LC-V?
The main relief valve pressure should be set to 350 bars (5,075 psi) for high-stage pressure. Standard relief pressure should be at least 330 bars (4,785 psi), but less than 335 bars (4,858 psi). p. 210
What is the correct track tension for the Solar 340LC-V?
For most terrain, the recommended track tension is 340 - 370 mm (13.39 - 14.57 in). For muddy ground, the clearance should be 370 - 410 mm (14.57 - 16.14 in), and for gravel, rocky terrain, sand, or snow, it should be approximately 410 mm (16.14 in). p. 139
What is the procedure for checking the swing relief valve pressure?
Connect two 600 bar (8,700 psi) pressure gauges to the inlet and outlet measuring ports on top of the swing motor. With both swing locks engaged, the pressure should be between 280 and 290 bar (4,060 psi and 4,205 psi). p. 217
What is the tightening torque for the main pump drive coupling clamping screws?
For the Solar 340LC-V, the tightening torque for the clamping screws (Tb) is 20 - 22 kg•m (145 - 159 ft lb). p. 192
