FAQ

Q: How do I confirm this sensor is compatible with my specific Hitachi excavator?
A: The most reliable method is to cross-reference the part number (4716888) from your machine’s official service parts manual or by physically checking the number on your failed sensor. Providing your machine’s model and serial number to our technical team can also facilitate verification.

Q: Is this a direct plug-and-play replacement, or is calibration required?
A: This is a direct replacement part designed to match OEM specifications. It is typically a plug-and-play component. However, after installation, it is good practice to check the hydraulic system’s performance parameters using the machine’s diagnostic system, as per the manufacturer’s service guidelines, to ensure optimal calibration.

Q: What are the common symptoms of a failing hydraulic pump angle sensor?
A: Common failure signs include erratic or weak hydraulic operation, unexpected loss of power in the boom or arm functions, the machine entering a “limp mode” with reduced engine power, and diagnostic trouble codes (DTCs) related to pump control or sensor signal plausibility.
