Before paragraph time, lang Yi of a masses will repair a factory to examine the issue of engine. Car advocate descriptive problem is: Engine idle fast shake apparent, engine room is started to still have the sound of Ka Ka when starting. Such problem allows a car advocate it is anxious very, already serious effect arrived to drive normally!
The master is in after receiving a car, it is to open what machine lid checks engine to shake first and abnormal knocking. Place of arrowhead laying a plan is shown, the master is used special stethoscopic will listen to engine abnormal knocking, idle fast when now and then appear. But, the master is using stethoscopic examination after common position, discover abnormal knocking and not be in engine is left, the problem place that where this meeting is is brought about?
Place of arrowhead laying a plan is shown, this position is the position of abnormal knocking of master check fish, be located in engine and gear-box union department. At this moment, after another experienced worker is checked, express directly: Bring about engine idle fast shake and the problem that the reason of abnormal knocking is engine flywheel, this problem is particularly common on this model.
And the travel course of development of this Lang Yi also just is to just exceeded 100 thousand kilometer, the travel course of development that following graph arrowhead place show. The master says, he has encountered a lot of similar case, thinking at the beginning is the problem of engine, trade the insoluble issue such as sparkplug, final ability fish is the problem of engine flywheel.
Because the flywheel of gear-box of this double separation and reunion and general flywheel are different,this still basically is, double quality flywheel, use time became long appear easily rusty, be out of shape wait for a problem, then brings about it to because Song Kuang is lopsided,appear and shake in movement the phenomenon such as abnormal knocking.
How should be this problem maintained? The master expresses: Tear open next gear-box maintenance! Have the free wheel that such ability change to be secured on engine only. Because do not have other settle way, after Lv of be in charge of an examination of bright ease car, agree with maintenance program of the master. Place laying a plan is shown, the batholith of this Lang Yi; Green arrowhead place is shown, the master is disassembling axle shaft; Orange arrowhead place is shown, this needs to tear open the gear-box below namely. ?
Through the effort of two many hours, two masters give transmission case tore open come down, because this a side of engine was done not have,prop up, need is propped up with the tool, following graph arrowhead place are shown, is special tool aing string of 1 engine? .
Place laying a plan is shown, this tears open the gear-box of double separation and reunion below namely. Appear easily as a result of the dual clutch inside it problem, so the master checks the dual clutch on this gear-box seriously, affirm without the problem!
Place laying a plan is shown, this is engine and the place that gear-box ties, flywheel has been torn open to fall by the master, it is to be in crankshaft is hind and fixed, namely the position that orange arrowhead place shows. Those who need an attention is, a lot of engine of this position hind oil seal appears easily the problem of leakage oil. ?
Place laying a plan is shown, this brings about engine to shake namely the flywheel with abnormal knocking, it and general flywheel are far apart. Green area place is shown, this position is to going up the position that place of the arrowhead in the graph shows is fixed, the dual clutch of this one side and gear-box is contacted. ?
Place of arrowhead laying a plan is shown, the master gives small pose the problem that demonstrates this flywheel, both hands is turning free wheel exterior, can dial those who move interior easily with handle gently annulus, roll still has abnormal knocking, and new flywheel? Won't appear such problem.
Finally, after installing new flywheel when the master, the engine that start, before won't appearing shake and the problem of abnormal knocking, it is the problem of flywheel. Nevertheless, the master expresses, before technology of present double separation and reunion is compared a few more ambitious, very few conference appears such problem!
