What to Do in Case of Unexcepted Engine Damage 滿足 分類: 未分類

At engine or transmission breakage each car owner faces a dilemma: what to choose - a partition or replacement of a detail. Each of options has the pluses and minuses, and, certainly, the reefs. In this article we will consider both options of a solution.
For modern engines the main reasons leading repair is wear of the valve mechanism: belt break, or jumping of a chain of valve machanism Autel MaxiPRO MP808TS, and also provorachivaniye of inserts. Major engines breakage are a consequence of untimely service and the inattentive relation of the owner to the car. The valve belt is recommended to be changed in aggregate with rollers and natyazhitely approximately each 60000 km in spite of the fact that the producer can recommend replacement and each 90000 km. Such measure allows to avoid a bending of valves and cylinder head case dissecting. Often at break of a cylinder head belt isn't subject to restoration. Only on the smallest number of cars break of valve mechanism doesn't involve consequences. The chain of valve mechanism is recommended to be changed together with VANOS (the mechanism of exact exposure of ignition), stars and tensioner at emergence of the extraneous noise arising because of stretching of a chain and wear of natyazhitel. Approximately the valve chain changes at 120-160 thousand run depending on degree of load of the engine throughout this run. А word about oil change: we may say that the change is needed to be done every 8000km for urban use and 10000-12000km for using out oftraffic jams.
Provorachivaniye of inserts most often arises at the expense of untimely replacement of oil (it loses the properties) or insufficient level of oil, or failure of the oil pump, in a consequence of that its pressure and the crankshaft mechanism falls remains without greasing. Consequences depending on engine turns at the time of this incident can be different - beginning from a banal provorachivaniye of inserts, elimination of that requires shaft polishing under 0.25 and replacement of inserts on repair, finishing punching of the block of cylinders, rod break, dissecting of cylynder head and dissecting of walls of the cylinder. In a case with the aluminum block the engine can be rescued sometimes in addition by means of argonny welding, sleeving cylinders, replacement of a shaft and other. In a case with the pig-iron block not to rescue the punched engine any more. Similar measures make sense at the weighed calculation of expenses since purchase of the contract engine leaves much cheaper than the above types of works in a technical center. In a case with boring under the first repair size (0.25) repair is quite justified and would will manage much cheaper than purchase at the unit. For more age engines, with run more than 250 thousand km are characteristic the increased consumption of oil. Often for elimination of similar malfunction it is enough to replace oil scraper caps. But unfortunately this measure happens not only: in most cases consumption of oil is a consequence of wear of walls of cylinders and piston rings. Measurement of a compression helps to define a condition of compression rings, and in a case with the lowered compression it is necessary to replace rings. At removal head beating of pistons in cylinders also is checked.
At its existence it is necessary either a motor gilzovka, or boring under repair pistons. In the second case, especially with V-shaped motors purchase contract motors will manage cheaper.
Any kind of motor works can be made in the specialized centers, for example a technical center "Motor Engineering"

Upon purchase of contract units also there are reefs: for cars of old years of release purchase at the unit with a high probability can turn back the subsequent partition Autel MaxiSys MS908, however engines for fresher cars purchase of the contract motor - good alternative to repair. At the moment engines in Russia are presented from the different countries of the world operation in which has the features. The goods from Baltic region unfortunately, don't differ high quality, engines from England differ small run and higher price. The goods from Belarus as a rule have the past on partitions in this country. Japanese units are distinguished by a good condition, existence of the hinged equipment and the low price. The goods from the Emirates also are distinguished by the low price, however in certain cases have a number of differences on covers and sensors. It makes sense to order contract units in the companies which provide a guarantee. In an ideal if the company which sells the engine offers option of installation is allows to save on installation in case the engine is low-quality. The majority of the companies selling motors, at installation at itself give the increased guarantee. The Motor Engineering company can become an example of the similar company. Also the priority makes sense to give to the companies which have a wide experience in the market, and also have in the staff of skilled experts. When replacing the contract unit for increase in its service life belt replacement valve belt with rollers, and also epiploons also is recommended. These actions allow to level risk of leakage of oil upon installation, and also risk of break of a belt because storage conditions of engines as a rule not in the best way affect a condition of a belt, especially it concerns engines of a Baltic origin.
