Daewoo Solar 330LC-V Common Problems This Manual Covers
Daewoo Solar 330LC-V hydraulic functions weak and erratic, pump noisy, metal grit in case drain oil
Test main relief pressure at the pump: 330 kg/sq cm in normal mode, per page 47. Pull a case drain sample; metallic grit means internal pump wear. Replace all hydraulic filters, then tear down the pump and measure cylinder bore to piston clearance against the specs on page 381; replace parts past the 0.070 mm limit.
Manual Section: Hydraulic System Troubleshooting, Testing and Adjustment p. 211Oil leaking from the center joint area under the cab, swing swivel seals weeping steadily
Inspect the center joint seals before condemning the whole swivel. Disassemble following the procedure starting on page 249, clean everything, and measure stem to body clearance; the limit is 0.1 mm (0.0039 in) per page 254. Replace all O-rings on reassembly and check the case drain line for blockage that pressurizes the seals.
Manual Section: Center Joint (Swivel) p. 249Swing coasts past target and feels rough, swing reduction gearbox running hot
Check the swing motor relief valve setting first: 270 kg/sq cm per page 284. Low relief pressure gives weak swing and coasting past the target. Drain the swing reduction gearbox oil and check for metal particles, then refill to the level plug. If rotation stays rough, follow the gearbox troubleshooting.
Manual Section: Swing Motor p. 277Travel sluggish or jerky on one side after hydraulic service, travel motor whines under load
Bleed air from the travel motor drain line after any hydraulic service before working the machine hard. Check pilot pressure to the travel control valve: full spool stroke needs 27 kg/sq cm per page 481. If one side still lags, swap travel lines side to side at the center joint to isolate motor from valve.
Manual Section: Travel Motor (with Gearbox) (Kawasaki Dnb Series) p. 303Tracks keep going loose, link pitch stretched, shoes and grousers wearing down fast
Measure grouser height on the standard 600 mm shoes: new is 31 mm, plan maintenance at 26 mm, replace at 21 mm, per the wear charts on page 149. Check link pitch against the 203.2 mm standard on the same chart. Adjust track sag with the grease adjuster and inspect rollers and idlers for flat spots.
Manual Section: Lower Structure and Chassis p. 149Frequently Asked Questions
How do I clear error codes on a Daewoo Solar 330LC-V excavator?
