FAQ


Q: What are the typical signs that the pump drive gear is failing?
A: Common symptoms include a high-pitched grinding sound from the pump area, increased vibration, or a total loss of hydraulic functions if the teeth have sheared. Inspecting the gear for "pitting" or "chipping" during routine maintenance is critical for avoiding catastrophic HPV118 failure.
 
Q: What are the technical requirements for a successful gear installation?
A: Ensure the pump shaft and mating gears are free of burrs or debris. It is essential to check the backlash and alignment after pressing the 3100993 gear onto the shaft. Use a professional hydraulic press to avoid damaging the gear teeth or the shaft splines.
 
Q: How do I confirm this gear is compatible with my Hitachi excavator?
A: This gear is specifically engineered for the Hitachi ZX200-3 and ZX210-3 equipped with the HPV118 hydraulic pump. Please verify the part number 3100993 and the tooth count against your existing gear to ensure a 100% correct match before ordering.
 
Q: How does this gear perform under extreme mining loads or temperatures?
A: The 3100993 gear maintains its metallurgical stability and structural integrity even when hydraulic oil temperatures fluctuate. The specialized heat treatment prevents the metal from becoming brittle in cold climates and resists softening in high-heat, 24/7 continuous duty mining cycles.

 

Q:  What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
