The clutch and the steering are two mechanical devices that the driver controls. However, one is used to getting damaged faster than the other: it is obviously the clutch mechanism. With of course the gearbox, which goes with it. Rather frequently, 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, this sometimes avoids having to change the complete kit. Here are the gearshift malfunctions the most common.
+ str (XXX) +: Impossible to pass one of the speeds
It happens regularly that one of the gears no longer works. Or only even or odd speeds. In this situation, the clutch is worn. However, this is not inevitably due to the whole clutch kit or gearbox of your + str (XXX) +. It is possible that the problem arises from a connecting rod or a rubber that holds it. The problem can still come from the gearbox. It can be removed to check that no foreign element is blocking it. If it is damaged, it will have to be changed.
Unable to change gear once the + str (XXX) + engine is started
This is unfortunately a rather frequent problem. Since the engine is off, it is still possible to change gears, this means that the gearbox of your + str (XXX) + is operational. Once the engine is on, it is impossible. The problem is with the clutch. In general it will be necessary to change the complete clutch kit. You can always put it down and check the condition of each part. As a reminder, it is still advisable to change the clutch every 150 km.
+ str (XXX) +: no speed passes
If none of the gears change, with the engine stopped as if on, it's really unpleasant. One thing to check is the condition of your str (XXX) + gearbox. There may be a high probability that it is out of service. To discern where the problem comes from is relatively simple. If you can squeeze the lever into the guide for a gear, but the gear doesn't engage, the clutch is probably having a problem. If the lever seems stuck and you can't push it, the problem is most likely with the gearbox. For one like the other, it will most certainly be necessary to change one or more parts.
