New Holland EW 160 Common Problems This Manual Covers
New Holland EW160 hydraulic system jerky movements, won't lift heavy loads properly
Depressurize the system first per the safety notes on page 11. Check hydraulic oil level against the 250 L system capacity on page 72, then inspect the return filter for clogging; a lit filter control lamp means don't cycle the control valve until it clears, per page 316. Bleed trapped air from the lines before testing lift function again.
Manual Section: Hydraulic System p. 299Engine won't start or cranks slow, especially in cold weather
Test battery output and acid density first using the procedures. Check the solenoid switch at terminal 50 for minimum 8.0 V pull-in voltage and verify voltage drop doesn't exceed 0.5 V, both specified on page 456. If cranking is weak but battery tests fine, inspect the starter motor connections for corrosion before condemning the starter itself.
Manual Section: Electrical SystemHydraulic fluid leaking from fittings with system running hot
Shut the machine down and depressurize per page 11 before touching any lines. Inspect hoses and fittings in the affected circuit for cracked seals or worn O-rings; the filter O-ring kit (P/N 73170669) and return filter O-ring (P/N 73171650) are listed on page 73. Replace damaged seals and refill to the 250 L rated capacity, checking for aeration as a cause of the overheating.
Manual Section: Hydraulic System p. 73Slow or unresponsive boom and bucket controls
Verify working pump oil flow falls within the 15 to 117 l/min operating range documented on page 67. Check the governing pressure sits between 5 and 40 bar; low flow at rated engine speed points to a worn pump or a control valve fault. Bleed air from the servo circuit and retest before replacing the pump itself.
Manual Section: Hydraulic System p. 67Error code E002 hydraulic overheating displayed on the monitor
Check the accumulator charging valve switch-off pressure against the 150 bar spec on page 341; a valve stuck open keeps the pump working against unnecessary load and drives temperatures up. Cross-reference the fault against the error code list, then inspect the oil cooler fins for debris blocking airflow before restarting the machine under load.
Manual Section: Electrical SystemSlew bearing feels loose or grinding noise during rotation
Check flank play between the swing bearing and slew pinion against the 0.3 +0.2 mm spec on page 74; play outside this range means the pinion needs shimming. Torque the mounting hex screws to 250 Nm as specified on page 75 for both undercarriage and superstructure connections. Regrease the bearing seals to prevent the dry-running wear that causes this noise in the first place.
Manual Section: Undercarriage p. 74Frequently Asked Questions
How to reset the error code on a New Holland EW160?
To extinguish the "ENGINE ERROR" message displayed on the control panel, press push-button (44) for approximately 2 seconds. This action cuts the electrical connection between the operating panel and the engine, stopping the buzzer and extinguishing the message. To reactivate the display and buzzer, turn the electrical system key-switch to position "0" and then back to position "I". p. 561
What are the torque specs for the main pump bolts on a New Holland EW160?
The hex screws (M 10 x 35, material grade 10.9) used to fasten the multi-circuit pump unit require a tightening torque of 60 Nm (44 lbft). This specification is crucial for proper installation of the hydraulic pumps. p. 398
How to reset the service interval counter on a New Holland EW160 wheeled excavator?
To reset the service interval counter, navigate to the "Special Functions" menu by pressing F6 in the "Main Menu", then press F6 again for "Control Panel". Select "Reset servicing interval" by depressing F1, and confirm the action by pressing "1". After cycling the ignition switch off and then on, the control panel will display the next servicing interval. p. 563
What is the reset procedure for the hydraulic pressure warning on a New Holland EW160?
The manual indicates that an optical and acoustical warning is triggered if the accumulated pressure in the diaphragm-type accumulators falls below 90 bars. While there isn't a specific "reset" procedure for the warning itself, resolving the underlying pressure issue, such as ensuring the accumulator charging valve functions correctly, should clear the warning. p. 341
