Yanmar B110W Common Problems This Manual Covers
Yanmar B110W excavator loses hydraulic power and boom response slows under heavy load. p. 52
Test the working pump standby pressure on page 52 to ensure it reads 22 +1 bar at 2,150 min-1. Check the main pressure relief valve pressure at upper idle. Adjust the relief valve to 380 bar if it falls below specification. Clean the hydraulic filters.
Manual Section: Technical DataEngine overheating warning activates and cooling performance drops during sustained trenching operations. p. 114
Inspect all cooling hoses for damage or dry rot. Renew if damaged as outlined on page 114. Check the coolant temperature warning threshold on page 707 to verify the sensor triggers above 110°C. Secure any loose connections and torque the coolant hose clips to 1.5 Nm.
Manual Section: Diesel EngineVisible hydraulic fluid leaks around cylinder fittings found during daily walk-around inspection. p. 813
Inspect the DKO hose connections with zinc-nickel surface protection. Clean the area around the leak. Torque the L15 M22 x 1.5 hydraulic hose fittings to 70 Nm for both initial and repeat assembly, as specified on page 813. Check cylinders for scored rods.
Manual Section: Repair InstructionsBoom assembly slowly lowers while holding a heavy load in the raised position. p. 59
Measure the boom cylinder drop rate with a dial indicator. Verify the boom cylinder TPA drift value does not exceed 3.5 mm/min according to page 59. Inspect the control valve spools for excessive wear or scoring. Replace the cylinder seals if the drift exceeds the maximum limit.
Manual Section: Technical DataFrequently Asked Questions
How do I reset the YANMAR B110W error code?
To reset the error code, rectify all errors. For some errors, it is necessary to switch off the ignition, wait 30 seconds, and then switch back on the ignition. The diagnostics lamp will go out once all errors are rectified.
How do I reset the hydraulic pressure settings on a YANMAR B110W?
Hydraulic pressure settings can be reset by adjusting the relevant screws. For instance, to adjust the pressure cut-off of the travel pump, screw in/out the setting screw (07) on the travel pump to increase or reduce pressure. For slewing drive pressure, unscrew the lock nut (2) and turn the pressure adjusting screw (1) clockwise to increase pressure or counter-clockwise to reduce it, then tighten the lock nut (2) against the connection nozzle (3).
What does the YANMAR B110W fault code mean?
The YANMAR B110W fault codes are listed in the 'ACTIA - Diagnostic Messaging Specification' and 'DTC-List-EMR4' sections. These lists provide the DTC Code (Hex), DTC Type, SPN-Value, Failure type, Function/Module, Number, and a detailed Description of the fault.
How do I clear the alarm on a YANMAR B110W?
The warning buzzer is activated under various fault conditions, such as low fuel level, high coolant temperature, or soiled air filter. To clear the alarm, the underlying fault condition must be resolved. For example, if the quick-attach function alarm sounds, it will stop once the function is deactivated.
