Why is it difficult to shift into first gear?
1 Answers
The reason why it is difficult to shift into first gear is due to lack of maintenance of the shifting mechanism or excessive wear of the gear lever ball seat. The details are as follows: Lack of maintenance of the shifting mechanism: The shifting mechanism is a frequently used component, so its wear level is relatively high. When the shifting mechanism lacks lubrication, the operation becomes abnormally stiff. Excessive wear of the gear lever ball seat: The ball pin seat of this vehicle has been completely worn out. Since the ball pin seat is absent, the gear lever ball pin moves upward under the action of the conical spring, maintaining contact with the shell hole, with its ball head plane protruding about 3-4mm above the shell hole plane. Due to the forward and backward movement distance generated when shifting into first gear or reverse gear without using a synchronizer. Therefore, when shifting into first gear or reverse gear, the lower end of the gear lever cannot push the sliding gear into place and disengages from above the groove of the first gear and reverse gear shift fork shaft movement block, preventing the first gear and reverse gear shift fork shaft from entering the correct position for shifting. As a result, first gear and reverse gear cannot be engaged.
