Fiat Kobelco E20.2SR, E22.2SR, E27.2SR Common Problems This Manual Covers
Fiat Kobelco E20.2SR bucket and arm slow, weak digging power, hydraulics groan under load
Check hydraulic oil temperature first; run pressure tests only at 50~60 °C (122~140 °F). Test main relief pressure against the 23.0 MPa (3340 psi) spec on page 93. If the reading is low, adjust or replace the relief valve, then follow the trouble diagnosis table on page 492 to isolate pump or pilot circuit faults.
Manual Section: Troubleshooting (Hydraulic System) p. 492Engine cranks but won't start, or starter barely turns over in cold weather
Check battery voltage and terminal condition, then follow the engine-does-not-start chart on page 501. Verify starter wiring and the magnetic switch contacts. In cold weather, confirm oil viscosity matches the 10W-30 or 15W-40 spec on page 554; heavy oil drags the starter. Test alternator V belt tension while the covers are off.
Manual Section: Troubleshooting (Electrical System) p. 501Machine travels crooked, one track runs slower than the other on flat ground
Measure crawler sag on both sides; rubber shoe tension should be 60~70 mm (2.4~2.8 in) per page 425. Adjust the idler grease cylinder to equalize both tracks. If deviation persists, swap the travel hoses side to side to separate a weak travel motor from a control valve fault, then continue with the procedures on page 492.
Manual Section: Travel System Disassembly and Assembly p. 425Slew motion sluggish, upper structure hesitates at start or won't rotate smoothly
Verify pilot relief pressure at 3.5 ± 0.4 MPa (508 ± 58 psi) per page 93; low pilot pressure starves the slew spool. Time a full rotation and compare against the 8.7 rpm slewing speed listed on page 28. If both check out, inspect the slewing motor brake valve and reduction gear using the disassembly procedures on page 293.
Manual Section: Slewing Operation Hydraulic TroubleshootingEngine down on power under load, black exhaust smoke, burns more fuel than normal
Clean or replace the air filter element first; a restricted intake is the usual cause. Check valve clearance and set intake and exhaust to 0.2 mm (0.008 in) cold, per page 35. Verify output against the rated 15.9 kW (21.6 PS) at 2200 rpm, then work the output-drops-down diagnosis starting on page 513.
Manual Section: Troubleshooting (Engine) & Supporting Data p. 513Frequently Asked Questions
What are the torque specifications for the main pump capscrews on the FIAT KOBELCO E27.2SR?
The capscrew (C4) used to fix the main pump requires a tightening torque of 85.3 N•m. This is a specific instruction for pump installation. p. 306
What is the total and effective engine oil capacity for the FIAT KOBELCO E20.2SR, which uses the 3TNV82A engine?
For the 3TNV82A engine, the total lubricant capacity (oil pan) is 3.6 liters, and the effective capacity is 1.2 liters. p. 541
What is the coolant water capacity for the FIAT KOBELCO E20.2SR engine only?
The coolant water capacity for the 3TNV82A engine only is 1.8 liters. p. 541
What is the V-belt tension (deflection) for a new V-belt on the engine?
For a new V-belt, the deflection should be 8~12 mm at position A, 5~8 mm at position B, and 7~11 mm at position C. p. 564
What is the standard main relief valve pressure for the FIAT KOBELCO E20.2SR?
The standard main relief valve pressure for the Boom, Bucket, and Travel (LH) P1 circuit on the E20.2SR is 23.0 MPa (3340 psi). p. 93
