4. FAQ

Q: Can this gasket kit be universally used for cooling system overhaul of all construction machinery?
A: It is dimensionally customized exclusively for motor grader water pump housing structures only. It cannot fit crawler excavator cooling assemblies, wheel loader gearboxes or medium roller hydraulic housings of other equipment series.

Q: What static working pressure can these composite gaskets endure during long-term coolant circulation?
A: The matched assembly can steadily bear static pressure ranging from 6.25MPa to 7.05MPa. It maintains tight sealing even if slight housing deformation occurs under bumpy operation vibration.

Q: What typical infrastructure projects need this water pump gasket kit for routine overhaul?
A: It supports regular maintenance of water pump housing sealing assemblies on motor graders, widely applied in highway reconstruction, airfield ground leveling, open-pit mine site trimming and rural road upgrading projects.

Q: How does the service life of these composite gaskets compare with ordinary single-layer fiber paper gaskets on the spare parts market?
A: The camellia leaf fiber reinforced composite structure improves creep resistance and coolant corrosion resistance remarkably. Under continuous vibration working conditions, its service life reaches more than 3.08 times that of standard fiber paper gaskets.

Q: How well can these gaskets compensate for minor surface unevenness on assembly flanges?
A: Graphite and fiber layers possess excellent compressibility. They can fill tiny gaps on joint surfaces and stop coolant seepage caused by minor machining imperfections of pump housings.

Q: What convenient benefits can field maintenance technicians obtain by using this integrated gasket kit?
A: All gaskets and adjusting shims required for full water pump overhaul are packed as one set. Technicians do not need to cut gaskets manually or source scattered spare parts, greatly shortening on-site disassembly and repair time.
