Shock Absorbers manufacturers how to solve gasket failure
Shock Absorbers manufacturers how to solve gasket failure.
Head gaskets typically fail at the weak point, which is the thinnest area between adjacent cylinders. The gasket cracks or burns through, allowing compression to leak between the cylinders. This causes a drastic drop in power that is hard to disregard. The locomotive engine may still operate, but very badly.
If the gasket leaks coolant, it may cause the locomotive engine to overheat. Coolant in the crankcase or cylinder is also not a good thing to have because it dilutes the oil and accelerates wear. If enough coolant leaks into a piston chamber, it may even "hydrolock" the locomotive engine preventing it from turning over when you attempt to start it.
Conditions such as locomotive engine overheating and abnormal combustion can also cause a head gasket to miscarry.
Improper installation may be another factor. If the person who installed the gasket did not torque the head bolts in the proper sequence or to the specified value, it can cause the gasket to leak and fail. Also, if the head and block were not fair, flat and finished properly when the gasket was originally installed, it could contribute to a leakage problem.
Some engines also have a reputation for eating head gaskets. The design of the head along with the location, size and load on the head bolts has a great deal to do with how long the head gasket will keep its seal. In some of these locomotives engine, the problem is the design of the locomotive engine while in others it is the design of the head gasket.
Gasket Replacement.
To replace a blown head gasket, the cylinder head must be removed from the locomotive engine. This can be a major undertaking depending on the type of locomotive engine you bet much other stuff has to be removed to pull the head.
Once the head is off, the mating surfaces of both the head and block should be inspected for flatness as well as any damage that might have contributed to the gasket's failure or might prevent a new gasket from sealing properly. If the head is warped, it will not seal the new gasket properly and sooner or later it will again fail. Resurfacing and or straightening the head may be necessary. An inspection of the head may also reveal cracks or other damage that will have to be repaired before it can go back on your locomotive engine.
You should know that several gasket manufacturers offer special "problem solving" head gaskets sure enough locomotives engine that have a high incidence of head gasket failure. These gaskets are often made of high heat materials such as graphite and have other special features such as additional combustion chamber armor, added sealing beads, more thickness, etc.
