The clutch and steering are two mechanical devices that the driver steers. One has said that it tends to deteriorate faster than the other: it is the clutch system naturally. With in particular the gearbox, which is closely linked. It happens relatively regularly that gearshift malfunctions occur on this + str (XXX) +. And even if the clutch is regularly involved, it sometimes happens that we have surprises about the source of the malfunctions. In addition, this occasionally avoids replacing the complete kit. Here are consequently the gearshift malfunctions the most regular.
+ str (XXX) +: Impossible to pass one of the speeds
It often happens that one of the gears no longer shifts. Or only even or odd speeds. In this case, the clutch is in poor condition. But this is not inevitably due to the whole clutch kit or gearbox of your + str (XXX) +. It sometimes happens that the problem comes from a link or from a rubber that holds it. The problem can still arise from the gearbox. You can drop it to verify that nothing foreign is blocking it. If it is damaged, it will have to be changed.
Unable to change gear once the + str (XXX) + engine is started
Unfortunately, this is a fairly recurring concern. Since the engine block is off it is possible to shift your gears, this means that the gearbox of the + str (XXX) + is in good condition. Once the engine block is running, it is impossible. The concern must come from the clutch. Generally it will be advisable to change the complete clutch kit. You can always disassemble it and look at the condition of each of the parts. As a reminder, it is advisable to change the clutch every 150 km.
+ str (XXX) +: no speed passes
If none of the gears pass, the engine stopped as lit, it's really unpleasant. The first thing to look at is the wear and tear on the gearbox of your + str (XXX) +. There is a high probability that the latter will be out of service. To discern where the concern comes from, it's rather simple. If you can push the lever into the guide of one of the speeds, but the speed does not engage, it is the clutch which certainly has a problem. If the lever seems to be stuck and you cannot push it, the problem probably comes from the gearbox. For both, it will most likely be necessary to change one or more parts.
