Clutch and steering are the two mechanical systems that the driver controls. One, however, is used to wear out faster than the other: it is the clutch system of course. With of course the gearbox, which goes with it. Rather frequently, gearshift concerns arise on the + str (XXX) +. And even if the clutch is regularly involved, it happens that we have surprises about the source of the worries. In addition, this sometimes avoids having to change the entire kit. So these are the gearshift concerns The most common.
+ str (XXX) +: Impossible to pass one of the speeds
It happens from time to time that one of the gears no longer changes. Or only even or odd speeds. In this situation, the clutch is in poor condition. But this is not inevitably due to the entire clutch kit or gearbox of your + str (XXX) +. It happens that the malfunction comes from a link or a rubber that holds it. The malfunction can still occur from the gearbox. You can drop it to check that nothing outside is blocking it. If it is defective, it must be replaced.
Unable to shift gear once the + str (XXX) + engine is running
Unfortunately, this is a fairly common malfunction. Since the engine is off, it is still possible to shift your gears, this implies that the gearbox of your + str (XXX) + is in good condition. Once the engine is started, it is impossible. The malfunction comes from the clutch. In general it will be necessary to change the entire clutch kit. You can always remove it and check the condition of each of the components. For your information, it is still recommended to change the clutch every 150 km.
+ str (XXX) +: no speed passes
If none of the gears pass, the engine stopped or in working order, it's really annoying. The first thing to check is the state of the gearbox of your + str (XXX) +. Chances are that it will be out of service. In order to understand where the malfunction comes from it's relatively simple. If you can put the lever in the guide of one of the gears, but the gear does not engage, it is the clutch which probably has a malfunction. If the lever seems to be blocked and you cannot push it, the malfunction probably comes from the gearbox. In both cases, you will most certainly have to change one or more parts.
