FAQ


Q: What operational failure symptoms indicate this pump repair kit needs immediate installation?
A: Drastic drops in hydraulic speed, high oil operating temperatures, and loud whining noises from the pump housing indicate worn sealing faces. Inspecting the oil filter for bronze particles confirms piston shoe or valve plate scoring.
 
Q: What are the critical lubrication and pre-start installation technical requirements?
A: Technicians must completely submerge all rotary kit components in clean hydraulic oil before housing assembly. Always fill the pump case with oil through the top drain port prior to engine start to prevent catastrophic dry running.
 
Q: How do procurement managers ensure correct pump model and part configuration match?
A: Verify the complete data plate stamping on your original pump casing, focusing specifically on model code A10VD43SR. Check whether your system requires a clockwise or counter-clockwise valve plate configuration before finalizing batch orders.
 
Q: How does this hydraulic rebuild kit perform under extreme high-pressure environment conditions?
A: The high-density metal components sustain stable structural flatness under continuous pressures up to 350 bar. The premium wear surfaces resist thermal breakdown during deep excavation tasks in ambient temperatures from -25°C to 90°C.
 
Q:  What quality options are available?

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