Kobelco SK17SR-5 Common Problems This Manual Covers
Kobelco SK17SR-5 engine will not start or only cranks slowly in cold weather conditions. p. 273
Inspect the battery terminals and ground wiring for corrosion. Test the starter motor output to verify it meets the 1.4 kW specification listed on page 92. If replacing the starter, torque the M10 mounting bolts to 32.5 to 43.4 ft•lbf (44.1 to 58.8 N•m) as detailed on page 273.
Manual Section: Starter Motor IssuesExcavator boom and bucket functions are weak, slow, or operate intermittently under heavy load. p. 24
Check the hydraulic oil tank level and top off to the 6.86 Gals (26 L) capacity specified on page 26. Test the system relief set pressure (P1, P2) and adjust to 2986 PSI (20.6 MPa) as shown on page 24. Inspect the wire gauze suction filter for debris.
Manual Section: Hydraulic Pump MalfunctionsMachine runs hot under load with the water temperature alarm lamp illuminating continuously. p. 28
Drain the cooling system and inspect the radiator for clogged fins or debris buildup. Check the intake valve clearance on a cold engine and adjust to 0.006 to 0.010 in (0.15 to 0.25 mm) according to page 28. Verify fuel injection pressure reaches 1784 to 1926 PSI (12.3 to 13.28 MPa) on page 29.
Manual Section: Engine OverheatingTracks wear out quickly, derail easily, or exhibit poor travel performance over rough terrain. p. 289
Inspect the undercarriage for damaged rollers and verify the track roller shaft diameter meets the Ø0.98 (Ø25) standard on page 46. Replace worn rollers and tighten the M12 mounting bolts to 57.9 to 72.3 ft•lbf (78.5 to 98.1 N•m) as instructed on page 289.
