The distance between the drive gear of the starter and the ring gear of the flywheel is too large  Adjust the size of the static position of the drive gear of the starter, normally 2-5mm
There is too much dirt on the exposed part of the shaft surface in the drive end cover of the starter, causing the one-way device to move slowly or jam on the shaft Regularly clean the dirt on the surface of the starter shaft to ensure the normal movement of the unidirectional device on the shaft.
