Every one of the 666 pages in this Doosan Solar 220LC-6 Shop Manual PDF (OEM #023-00058E) exists to put your track excavator back to work, and it covers the Solar 130LC-V, 170LC-V, 220LC-V, and 220N-V too. Open to full hydraulic and electrical schematics, then work through factory troubleshooting for the main pump, swing motor, travel motors, and Kayaba main control valve. You also get a complete standard torque section for metric and U.S. fasteners, split flanges, and hose clamps, plus rebuild steps for the swing bearing, cylinders, and track assembly. Pull the fuel tank mounting bolts to 27 kg•m, and swap lower rollers once axle wear passes 68.60 mm (2.70 in) from the 70 mm new dimension. Downtime on a machine this size gets expensive fast. Search any spec by keyword, or jump by bookmark straight to the section you need.

Doosan Solar 220LC-6 Common Problems This Manual Covers
Doosan Solar 220LC-6 hydraulics slow and weak, pump whines under load, boom raises sluggishly
Check hydraulic oil level first; the reservoir holds 140 liters and low fluid pulls air into the suction line. Bleed the system, then gauge main relief pressure against the 330 kg/cm2 normal spec on page 63. If pressure stays low with full, clean oil, suspect pump regulator wear or internal valve leakage.
Manual Section: Hydraulic System Troubleshooting p. 63Machine pulls to one side during travel, one track drags or stalls on grades
Test travel motor relief pressure on the weak side; spec is 350 kg/cm2, listed on page 371. Swap gauge readings side to side to isolate a bad motor from a valve problem. Check travel control valve secondary pressure as well, it should reach 27 kg/cm2 at full pedal stroke per page 535.
Manual Section: Travel Motor Troubleshooting p. 371Tracks keep coming loose or throwing off the front idler, undercarriage clatters at travel speed
Measure front idler axle wear before blaming tension; new dimension is 75.0 mm and the limit for use is 74.20 mm, shown on page 172. Check lower roller axles the same way against their 68.30 mm wear limit. Replace anything past limits, then set track tension per the Track Assembly procedure.
Manual Section: Track Assembly p. 172Joystick controls unresponsive or jerky, attachment moves only after long lever delay
Verify pilot pressure at the joystick before tearing into the main valve. The pilot control valve should deliver 28 kg/cm2 secondary pressure at full stroke, spec on page 513. If pressure is low, inspect the pilot supply line and pressure reduction valve. Clean sticking spools; jerky response usually traces to pilot circuit contamination.
Manual Section: Pilot Control Valve (Work Lever / Joystick) p. 513Swing gearbox runs hot and growls during rotation, oil seeping around the housing
Drain the swing reduction gearbox and inspect the old oil for metal flakes that point to bearing or gear wear. Refill with fresh gear oil; capacity is 6 liters, spec on page 161. Check case sealing surfaces for damage, then confirm the level again after a short swing cycle warms the box.
Manual Section: Swing Gearbox Troubleshooting p. 161Frequently Asked Questions
How do I reset the maintenance hours for filters and oils on a Doosan Solar 220LC-6?
To reset the operating hours for filters and oils, navigate to the 'Filter/Oil information' mode on the instrument panel. After changing the filter and oil, you can reset the operating hour so that the time until the next service interval can be easily checked. p. 589
How do I delete the memorized record of past failures on the e-EPOS controller?
To delete past failure records, enter the 'Failure Info' sub-menu and select 'Delete Fail Log'. When the 'YES' button is pressed, the memorized record will be deleted. This screen will be displayed for 3 seconds during the deletion process. p. 598
What is the torque specification for the counterweight mounting bolts on a Solar 220LC-6?
The mounting bolts for the counterweight on a Solar 220LC-6 must be tightened to a torque of 250 kg•m (1,807 ft lb). p. 113
What is the fuel tank capacity for the Solar 220LC-6?
The fuel tank capacity for the Solar 220LC-6 is 350 liters (93 U.S. gal). p. 119
What is the correct gear oil capacity for the swing reduction gearbox?
The swing reduction gearbox should be filled with 6 liters (6.3 quarts) of gear oil. p. 161
