Fiat Kobelco SL30B Common Problems This Manual Covers
Fiat Kobelco SL30B cranks but will not fire, hard starting cold, glow plugs suspect
Test battery voltage first; a healthy battery reads 12.5 to 12.6 volts, per page 80. Check glow plug resistance while you are in there, 1.0 to 1.2 ohms per plug. If the electrics pass, replace the fuel filter, tighten the new element 1/2 to 3/4 of a turn after gasket contact, then bleed air with the primer pump.
Manual Section: Electrical Specifications and Troubleshooting p. 80Loader arms lift slowly and bucket loses power under load, hydraulics feel weak
Check hydraulic reservoir level first; the total system holds 28.4 litres. If the fluid is milky or dark, drain it and change the filter. If the level is good, flow-test the pump using the procedure on page 221: expect 36.3 L/min at 2400 r/min at 138 bar. Output below spec means a worn pump, not a valve problem.
Manual Section: Hydraulic System Troubleshooting p. 221Engine overheats after an hour of work, temperature gauge climbs, coolant boils over
Check coolant level with the engine cold; the system holds 6.6 litres, per page 25. Blow chaff out of the radiator fins from the fan side. Clean the air cleaner element with compressed air at no more than 206 kPa, nozzle at least 25 mm from the pleats, per page 45. If it still runs hot, replace the thermostat.
Manual Section: Engine Troubleshooting p. 45Drive response is jerky, one side lags, machine loses power pushing into the pile
Test charge pressure using the procedure starting on page 117; minimum acceptable is 9.0 bar. Low charge starves the tandem piston pumps and causes lag. Check hydraulic oil level and filter condition first, then run the circuit relief and leakage tests in the same section. Also measure chain deflection, 6 to 25 mm, before blaming the pumps.
Manual Section: Hydrostatic System Troubleshooting p. 117Hydraulic hoses seep at the fittings, oil film building up on the loader arms
Wipe the fittings clean, cycle the loader, and find the exact leak point before touching a wrench. Torque O-ring boss fittings per the chart on page 20; a 3/4-16 fitting takes 70 to 78 Newton metres. Use the page 19 chart for 37 degree flare fittings. Replace any hose with a cracked cover or wet crimp instead of overtightening.
Manual Section: Standard Torque Specifications p. 20Frequently Asked Questions
What are the torque specifications for wheel nuts on the Fiat Kobelco SL30B?
The wheel nuts on the Fiat Kobelco SL30B must be tightened to a torque of 81 to 95 Nm. If the machine is new or the wheels have just been installed, check the wheel nuts every two hours until they remain tight. p. 200
How do I bleed the hydraulic system on the Fiat Kobelco SL30B?
To bleed the hydraulic system, start the engine at low idle and operate all cylinders through several complete cycles to remove any air from the circuits. Check the hydraulic oil level frequently during this process and add oil as required. p. 214
What is the recommended service interval for cleaning the air cleaner dust cup?
The dust cup must be cleaned after every 10 hours of operation or daily, whichever occurs first. If the machine is operated in bad conditions, clean the dust cup several times during the period of operation. p. 45
What is the engine oil capacity for the Fiat Kobelco SL30B?
The engine crankcase capacity for the Fiat Kobelco SL30B is 6.34 litres when performing a filter change. p. 25
What is the correct drive belt deflection for the alternator?
The drive belt deflection for the alternator must be 10 to 13 mm when pushed with approximately 10 kg of force. p. 68
