FAQ


Q: What specific fault symptoms indicate a failing 718437 swash plate and support?
A: Common signs include "jerky" hydraulic response, increased pump noise, and metal contaminants in the hydraulic filters. If your SK350 exhibits pressure fluctuations, the 718437 assembly may be scored or the support bearing surfaces worn, requiring immediate replacement to prevent pump seizure.
 
Q: What are the critical technical requirements for installing the K5V140 support assembly?
A: Proper alignment of the tilting cradle is vital. Ensure all mating surfaces are cleaned and pre-lubricated with high-grade hydraulic oil. It is recommended to replace the support bearings simultaneously with the 718437 plate to ensure a balanced contact pattern and prevent premature wear.
 
Q: How do I confirm this assembly is compatible with my specific pump model?
A: This kit is engineered for K5V140 and K3V112DT pumps commonly found in SK350 series excavators. Please verify your pump's serial number and nameplate. Cross-referencing part number 718437 ensures a 100% match for your technical procurement needs.
 
Q: How does this assembly maintain performance in extreme mining environments?
A: The 718437 is designed to withstand thermal expansion and high-pressure cycling. Its metallurgical composition remains stable from -25 up to 110 Degrees Celsius, ensuring the swash plate maintains precise angling even during 24/7 heavy-duty operations in extreme climate zones.
 
Q:  What quality options are available?

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