FAQ


Q: How can I diagnose if the 711703 piston assembly is the cause of my DH225-7’s slow travel?
A: Check for excessive case drain flow and a drop in system operating pressure. If the pump housing feels unusually hot, it often indicates oil is bypassing the 711703 pistons due to excessive clearance or surface scoring.
 
Q: What are the critical installation steps to ensure the longevity of the 711703 assembly?
A: You must check the cylinder block bore for wear before fitting. Always lubricate the 711703 pistons with clean hydraulic oil during assembly and ensure the piston shoes are properly seated on the swash plate.
 
Q: Is this 711703 assembly compatible with both Daewoo and Hyundai models?
A: Yes, it is designed for the JMV147 pump commonly found in Daewoo DH225-7 and Hyundai R200 series, providing a versatile inventory solution for multi-brand spare parts distributors.
 
Q: How does the 711703 assembly perform in high-dust and high-temperature mining sites?
A: The bimetal construction is designed to maintain structural hardness up to 110°C. When used with high-quality filtration, the 711703 resists abrasive wear from fine particles common in extreme mining environments.
 
Q:  What quality options are available?

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