Fiat Kobelco E70SR EVOLUTION Common Problems This Manual Covers
Fiat Kobelco E70SR Evolution travels weak on one side, tracks pull left or right under load
Check travel motor inlet pressure and pilot pressure using the hydraulic-system troubleshooting charts that start on p. 571. Verify the main relief valve holds its 300 kgf/cm2 (4270 psi) setting listed on page 226. Inspect the swivel joint for internal leakage between travel circuits, and swap crossover lines to isolate the weak side.
Manual Section: Hydraulic System Troubleshooting p. 571All hydraulic functions slow and jerky, boom and arm lose power when digging
Check hydraulic oil level first; the tank holds 78 L and low oil starves the pump. Replace the return filter if it has run past its 200 hour interval, then test main relief pressure against the 300 kgf/cm2 spec on page 226. If pressure still sags, work through the pump regulator checks starting.
Manual Section: Hydraulic System Troubleshooting p. 398Engine cranks slowly or starter just clicks, no start on cold mornings
Test battery voltage and clean both cable connections before condemning the starter. Bench test the starter with no load: it should draw 80 A max and spin at least 3,750 rpm at 23 V per the values on page 776. Measure brush length while it is apart; replace brushes worn down to the 11 mm limit.
Manual Section: Engine Troubleshooting p. 776Swing motor groans under load, metal powder found in the drained oil filter
Drain the swing reduction gear and inspect the oil for metal powder; refill with 1.5 L of gear lubricant per page 252. Cut open the return filter and check for debris that points to internal motor wear. If the swing port relief valve was disturbed, torque it to 4 kgf·m (29 lbf·ft).
Manual Section: Hydraulic System Troubleshooting p. 252Controller flashes E19 travel straight valve code, buzzer sounds and functions drop out
Check the travel straight solenoid coil resistance at the valve connector: a selector coil should read 34 ± 2 Ω and a proportionate coil 17.5 Ω at 20°C, both listed on page 296. Inspect the harness for chafing back to the controller, then clear the code and load test the travel circuit after repair.
Manual Section: Mechatro Control System Troubleshooting p. 296Frequently Asked Questions
What are the error codes for the Mechatro controller on the Fiat Kobelco E70SR Evolution?
The error codes for the Mechatro controller are listed in the troubleshooting section. For example, E01 indicates an EEPROM data error, E02 indicates a Mechatro controller maladjustment, and E03 indicates a fault on the boom raise pressure sensor. Corrective actions for these codes typically involve inspecting the harness, replacing the sensor, or replacing the controller. p. 106
How do I enter the service diagnostic mode on the Fiat Kobelco E70SR Evolution?
To enter service diagnostics, remove the grommet on the controller to access the hardware check switches (A) and (B). Insert a precision driver into the convex place indicated by the arrow and turn the arrow to set the switch to the desired numeric value to display diagnostic information on the LCD. p. 107
What is the tightening torque for the track motor mounting bolts on the Fiat Kobelco E70SR Evolution?
The tightening torque for the travel motor mounting bolts (M16 X 40) is 28.5 kgf·m (210 lbf·ft). p. 485
What is the replacement interval for the hydraulic oil and return filter?
The hydraulic oil should be changed every 600 hours, and the return filter should be changed every 200 hours. p. 896
What is the standard valve clearance for the engine on the Fiat Kobelco E70SR Evolution?
The standard valve clearance for both intake and exhaust valves in a cold condition is 0.40 mm (0.016 in). p. 643
