Fiat Kobelco E30SR & E35SR Evolution Common Problems This Manual Covers
Fiat Kobelco E30SR Evolution hydraulic pump grinding noise after 2000 hours, bucket won't lift
Check the hydraulic troubleshooting chart on page 498 for pump and relief valve diagnosis. Test main relief valve pressure at the test port; per the schematic on page 103, P1 and P2 should hold 230 kgf/cm2 (3270 psi). If pressure reads low, pull the return filter element (P/N Y-464900, page 102) and inspect for debris, or remove the pump for internal wear.
Manual Section: Hydraulic System Troubleshooting (General Diagnosis) p. 498Engine won't start or cranks slowly in cold weather despite fresh battery and fuel
Check the electrical troubleshooting chart on page 508 for starter circuit faults. With the key ON, verify 12V at the B terminal of the key switch; no reading points to a blown fuse. Test the S terminal at the starter motor for 12V during crank, and confirm coolant temperature per page 520 before suspecting the thermostat.
Manual Section: Electrical System Troubleshooting (Detailed) p. 508Track slippage or rapid roller wear developing well before the scheduled maintenance interval
Measure upper roller tread diameter against the standard value of Ø75 mm (2.95 in) listed on page 34; excessive wear below this reduces track contact and causes slippage. Check track tension and adjust per the maintenance schedule on page 84. Replace rollers showing flat spots, scoring, or flange wear rather than regreasing and hoping for the best.
Manual Section: Specifications p. 34Boom or arm attachment moves sluggish or fails to respond to control lever input
Inspect the control valve solenoid wiring and connector for corrosion or a loose ground. Torque the solenoid mounting bolts to 4.5 ± 0.5 kgf·m (33 ± 4 lbf·ft) per page 258, and check O-ring fittings for leaks, tightening 1/4 PF connections to 2.7 kgf·m (20 lbf·ft) as shown on page 331. Replace the solenoid if it fails to click when energized.
Manual Section: Control Valve Troubleshooting (Failure & Corrective Action)Swing motor leaks oil externally or hesitates when rotating the upper structure
Check the pilot pressure pump delivery pressure at approximately 3.5 kgf/cm2 (50 psi), noted on page 501, since low pilot pressure causes sluggish slew response. Inspect the swing motor case drain and shaft seal for external oil leakage, and check flange bolts for looseness. Replace the shaft seal if oil appears at the motor housing after cleaning and re-testing.
Manual Section: Slewing Motor TroubleshootingFrequently Asked Questions
What are the torque specifications for the main pump mounting bolts on Fiat Kobelco E30SR?
The main pump is fixed by capscrews (C4). The tightening torque for these capscrews is 8.7 kgf·m (63 lbf·ft). This torque value is indicated in a note on the pump installation diagram. p. 322
What are the torque specifications for the swing motor mounting bolts on Fiat Kobelco E35SR Evolution?
To remove the slewing motor, five M12X40 capscrews (3) are unscrewed. For installation, the tightening torque for these capscrews is 11.7 kgf·m (85 lbf·ft). p. 334
What are the replacement specifications for the Hydraulic pump?
For the E30SR EVOLUTION, the hydraulic pump model is AP2D16LV3RS7-915-0 with a dry weight of 27.5 kg (61 lb). For the E35SR EVOLUTION, the model is AP2D16LV3RS7-914-0, also with a dry weight of 27.5 kg (61 lb). p. 177
What are the replacement specifications for Track rollers?
For lower rollers, if the tread diameter reaches the service limit of ø69 (2.72) mm, the roller should be replaced. If the bearing shows peeling, galling, dent, rust, or discoloration, it should be replaced. p. 430
What is the engine oil volume for the Fiat Kobelco E30SR EVOLUTION?
The engine oil volume for the Fiat Kobelco E30SR EVOLUTION is 3.9 liters maximum and 1.2 liters effective. This corresponds to 1.03 gallons maximum and 0.32 gallons effective. p. 35
