The clutch and the steering are the two mechanical systems that the driver controls. One nevertheless tends to wear out more quickly than the other: it is of course the clutch mechanism. With in particular the gearbox, which is closely linked. Rather, it often happens that gearshift malfunctions occur on the + str (XXX) +. And even if the clutch is regularly involved, it sometimes happens that we are surprised at the reason for the malfunctions. In addition, it sometimes avoids replacing the complete kit. Here are the gearshift malfunctions the most usual.
+ str (XXX) +: Impossible to pass one of the speeds
It happens regularly that one of the gears no longer works. Or just even or odd speeds. The clutch is therefore worn out. However, this is not necessarily linked to the entire clutch kit or gearbox of your + str (XXX) +. Sometimes the problem is with a connecting rod or a rubber that holds it. The problem can also arise from the gearbox. You can remove it to check that no foreign component is blocking it. If it is damaged, you need to change it.
Unable to change gear once the + str (XXX) + engine is started
This is unfortunately a rather recurring problem. Since the engine block is off, it is possible to change your gears, this implies that the gearbox of your + str (XXX) + is operational. Once the engine block is running, it is impossible. The problem is with the clutch. In general, it will be essential to replace the complete clutch kit. You can always take it apart and look at the condition of all the parts. For information, it is advisable to replace the clutch every 150 km.
+ str (XXX) +: no speed passes
If none of the gears are working with the engine off or running, it's really unpleasant. The first thing to look at is the wear on the gearbox of your + str (XXX) +. There is a high probability that the latter is out of service. To discern where the problem comes from is rather easy. If you can squeeze the lever into the guide of one of the speeds, but the speed does not engage, the clutch is definitely having a problem. If the lever seems stuck and you can't push it, the problem is probably with the gearbox. For both, you will most likely need to replace one or more parts.
