The clutch and the steering are the two mechanical systems that the driver controls. One nevertheless has the habit of being damaged more quickly than the other: it is the clutch device naturally. With of course the gearbox, which is closely related. It happens relatively regularly that gearshift problems occur on the + str (XXX) +. And even though the clutch is often involved, it sometimes happens that we have surprises about the source of the problems. In addition, it sometimes avoids replacing the entire kit. So here are the gear change issues The most common.
+ str (XXX) +: Impossible to pass one of the speeds
It sometimes happens that one of the gears no longer works. Or just even or odd speeds. In this situation, the clutch is worn. However, this is not necessarily due to the entire clutch kit or gearbox of your + str (XXX) +. The problem may be with a connecting rod or a rubber that holds it in place. The problem can also come from the gearbox. You can dismantle it to check that no external element is blocking it. If it is damaged, you must replace it.
Unable to change gear once the + str (XXX) + engine is started
Unfortunately, this is a fairly common problem. Since the engine block is off, it is possible to shift gears, which means that the + str (XXX) + gearbox is in good condition. Once the engine block is running, it is impossible. The problem is with the clutch. Often it will be advisable to change the entire clutch kit. You can try to remove it and look at the condition of each of the components. For information, it is recommended to change the clutch every 150 km.
+ str (XXX) +: no speed passes
If none of the gears change, the engine off as on, it's really annoying. The first thing to look at is the wear on the gearbox of your + str (XXX) +. There is a good chance that the latter is HS. In order to understand where the problem comes from it is relatively simple. If you can put the lever in the guide of a gear, but it won't engage, the clutch is likely the problem. If the lever seems stuck and you can't push it, the problem is most likely with the gearbox. For both of them, you most likely have to change one or more parts.
