It’s no secret that the engine’s timing chain wears out over time and needs to be replaced. Similar work, which has already become routine, is done in most
Incidents happen immediately after replacing the chain along with the tensioners. After some time, the driver notices that the behavior of the “iron horse” has changed. Vibrations appeared, fuel consumption increased. And sometimes, even on the first attempt, the engine runs erratically, with severe cuts, or refuses to start at all. The starter turns, but does not make sense. However, the customer is in shock, as are the military. What is the cause of the problems?
Of course, marriage does not have to be ruled out. Let’s say the chain could jump a tooth due to the installation of a poor quality tensioner. However, this rarely happens, since in the vast majority of cases they use “native” spare parts. More often, during the assembly process, unlucky masters damage one of the sensors. There are plenty of them: a mass airflow sensor, temperature or throttle position. They start throwing surprises as soon as the car owner has left the repair zone.
And sometimes problems pass right by. Their reasons are negligence or haste. The fact is that in such work it is necessary to use special stoppers. They are necessary to fix the crankshaft in one position. That is, at top dead center of the first cylinder. Small details allow you to place the timing mechanism on the marks, that is, in the correct position.
Trying to do the job faster, the masters “forget” these spare parts. They quickly change the “locksmith” and start assembling the engine. The result – an attempt to start it ends either with the fact that the device does not want to work, or even with its complete failure.
You must disassemble the “motor” a second time and repeat the procedure. What happened? There was a situation when, after replacing even one chain tensioner, the whole mechanism shifted slightly, and the phases jumped literally by a fraction of a millimeter. This is enough for the engine to show no signs of life. So make sure that the masters are sure that they use the same stoppers.
