4. FAQ

Q: What continuous working temperature range allows this whole gasket kit to keep reliable sealing performance?
A: Its applicable temperature range covers -161°C to 443°C, suitable for cold region winter quarry loading and long-duration heavy material transportation work in high-temperature stockyards.

Q: Are all gaskets manufactured according to standard installation dimensions?
A: Every gasket is precision stamped to match engine assembly surfaces precisely.

Q: What typical failure signs show that main pump gaskets need replacement?
A: Persistent oil leakage from pump joint surface, oil seepage at shaft output end, pressure instability and abnormal pump noise during operation.

Q: How should we store these gaskets and rubber seals before installation?
A: Store in dry and ventilated place, avoid squeezing thin paper gaskets, keep away from grease solvent and long‑time sunlight exposure.

Q: Do I need to replace the pump metal housing while fitting this new gasket kit?
A: There is no need to change metal housings, only replace all gaskets and seals; please clean mating surface thoroughly before reassembly.

Q: Can these gaskets prevent oil seepage, water leakage and gas blow-by simultaneously?
A: Good compressibility ensures close fitting to block liquid and gas leakage on joint surfaces.

Q: Can this kit effectively prevent both internal leakage and external oil seepage?
A: Precision dimension design helps minimize internal flow loss and surface oil leakage.

Q: How effectively can these gaskets compensate for minor surface unevenness on assembly flanges?
A: Graphite and fiber layers possess favorable compressibility. They can fill tiny gaps on mating surfaces and block transmission oil seepage caused by minor machining defects of transmission housings.

Q: What convenient benefits can maintenance staff obtain by adopting this integrated gasket kit?
A: All gaskets and adjusting shims required for full transmission housing overhaul are packed as one set. Technicians do not need to cut gaskets manually or collect scattered spare parts, effectively shortening on-site repair time.
