Doosan DX180LC-3 Common Problems This Manual Covers
Doosan DX180LC-3 swing gearbox grinding noise, upper structure won't rotate or rotates slowly under load
Drain the gearbox oil and inspect it for metal flakes before disassembly. Check the No.1 sun gear (23 teeth) and ring gear (82 teeth) for chipped or worn teeth against the specs on page 371, then replace damaged gears and bearings. After reassembly, confirm brake torque holds at 63 kg•m before returning the machine to work.
Manual Section: Swing Device Troubleshooting and Oil Leakage p. 371Hydraulic oil leaking from swing motor housing and hose fittings after reassembly
Check every flange bolt on the motor mounting surface; a loose bolt or warped flange is the usual cause per page 389. Remove the motor, replace the oil seal and O-rings, clean both mating surfaces, reapply Loctite, and torque the bolts using the standard torque table on page 130. Refill the hydraulic system to its 210 liter capacity.
Manual Section: Swing Device Troubleshooting and Oil Leakage p. 389Swing gearbox casing runs excessively hot with irregular noise during continuous slewing
Drain the gearbox oil and check it for metal particles, then refill to the specified level as page 297 directs. Let the oil temperature come down before further testing. Test main relief pressure at the pump; anything above the 330 kg/cm2 normal setting works the swing circuit hard and overheats the oil.
Manual Section: Hydraulic System General Troubleshooting p. 297Error code E010 flashes intermittently on the gauge panel during swing operations
The error code E010 is not listed in the manual. For issues related to swing pressure, refer to error code V000251 'Swing Press. Sensor' on page 768. Troubleshooting for swing system problems, including pressure issues, can be found on page 296. Verify actual relief pressure with a gauge; the normal operation setting is 330 kg/cm2 per page 96. Replace the sensor only if the gauge disagrees with the panel.

What are the torque specifications for Doosan DX180LC-3 hydraulic connections?
Torque specifications for hydraulic connections vary by type. For ORFS swivel nuts, a Dash Size 4 with 1/4" hose I.D. and 9/16" thread requires 2.4 - 2.6 kg•m. Split flange connections for a 1/2" flange size with 5/16" bolts require 2.1 - 2.5 kg•m (15 - 18 ft-lb). p. 134
How to reset the Doosan DX180LC-3 engine maintenance light?
To reset the engine maintenance light, access the 'Filter/Oil Information' screen via the jog switch. Locate the cursor to 'Engine oil' or 'Engine oil filter' and click the jog switch to access the reset option for the operation hour. This procedure is detailed on page 726. p. 726
What do error codes E0, E1, E2, and E3 mean on the Doosan DX180LC-3?
The error codes indicate specific sensor issues. E0 means 'Normal' operation. E1 signifies an 'Internal air temperature sensor short', E2 indicates an 'Internal air temperature sensor open', and E3 points to an 'Ambient air temperature sensor short'. These codes are listed in the 'Error codes' table on page 135. p. 827
How to reset the Doosan DX180LC-3 diesel filter warning?
To reset the diesel filter warning, navigate to the 'Filter/Oil Information' screen using the jog switch. Position the cursor on 'Fuel filter' and click the jog switch to access the reset option for the operation hour. This process is outlined on page 726. p. 726
