4. FAQ

Q: What sealing difficulties is this gasket kit designed to solve for motor grader engine assemblies?
A: It focuses on static joint sealing of engine covers and housing flanges. Multi-material matching adapts to continuous road vibration and varying ambient temperature to prevent engine oil and hot gas leakage on mating surfaces.

Q: What continuous working temperature range can this whole gasket kit maintain stable sealing performance?
A: Its applicable temperature range covers -160°C to 442°C, suitable for cold plateau winter road construction and long-duration grading work in high-temperature open mining areas.

Q: Can this gasket kit be universally adopted for engine overhaul of all construction machinery?
A: It is dimensionally customized exclusively for motor grader engine cover structures only. It cannot fit crawler excavator engine housings, wheel loader gearboxes or medium-sized roller hydraulic assemblies of other equipment series.

Q: What static working pressure can these composite gaskets sustain during long-term grading operation?
A: The matched assembly can steadily withstand static pressure ranging from 6.28MPa to 7.08MPa. It can keep reliable sealing even if slight housing deformation occurs under frequent bumpy vibration.

Q: What typical infrastructure projects require this engine cover gasket kit for regular maintenance?
A: It serves routine overhaul of engine cover sealing assemblies on motor graders, widely applied in highway paving, rural road renovation, airport site leveling and open-pit mine surface trimming projects.
