Daewoo Solar 290LL Common Problems This Manual Covers
Daewoo Solar 290LL hydraulic functions weak and slow, oil running hot after an hour of digging
Check hydraulic oil level and condition first, then pull the return line filter; the return and pilot circuits both run 10 micron full flow filters, covered on page 181. Test main relief pressure against the 330 kg/cm3 (4,689 psi) spec on page 44. Clean the 177 micron reservoir intake strainer whenever you drain the system.
Manual Section: Hydraulic Problems Troubleshooting p. 181Engine overheats and loses power under load, temperature gauge climbing into the red
Shut down and blow out the radiator and cooling package cores with compressed air from the fan side. Clean the outer air filter element every 500 hours and replace it at 1000 hours, as laid out on page 153. Verify coolant level with the engine cold, then inspect the fan belt tension and thermostat.
Manual Section: Engine and Drive Train p. 153Tracks loose, popping over the sprocket, or throwing a track when turning on slopes
Measure link wear before cranking up tension; the master link A dimension is 117.30 mm (4.62 in.) new and hits the replacement limit at 103 mm (4.055 in.), shown on page 135. Check lower rollers and front idlers against the wear tables on pages 136 through 138, then grease the track adjuster to set sag.
Manual Section: Lower Structure and Chassis p. 135Swing sluggish or uneven, upper structure coasts past the stopping point
Test swing motor inlet and outlet pressure with the swing locks engaged; expect 280 to 290 bar (4,060 to 4,205 psi), the spec on page 199. Verify the hydraulic brake SH port sees 4 bar (58 psi) release pressure. Drain a sample from the swing reduction gearbox and check for metal before condemning the motor.
