What's with the shaking of the big truck at the start?

Generally, it is caused by serious wear of clutch friction plate. The clutch plate is badly worn, which will make the connection between the engine and the gearbox unstable and lead to vehicle jitter. Frequent overload and semi-clutch state will make the clutch wear seriously. Generally, vehicles that run long distances and take highways cannot replace the clutch plates for two or three years.

If the clutch is used frequently, the service life of the clutch will be shortened accordingly, which has a great relationship with the driver's operating habits. Just replace the clutch plate in time in the overhaul factory, otherwise it will be very troublesome if it breaks down halfway.
