The so-called lost files, refers to the vehicle in the road, the gear lever automatically return to the neutral position, the sliding gear is disengaged from the normal position. The so-called random files, which means that the gear can not be linked to the required gear, or not to enter the required gear, but into the other stalls, the vehicle can not be manipulated, and even the occurrence of accidents. Random files, lost files is one of the common faults, there is some connection between the two is due North Benz V3 transmission parts mechanical wear loose damage, or improper clearance adjustment.
Cause analysis:
1 beiben V3 accessories lever pin wear loose, broken or missing, causing it to lose control and arbitrary chaotic pendulum.
2 gear shift fork shaft locking device abrasion failure; transmission rod ball head wear big open.
3 gear, ring gear or gear sleeve in the direction of tooth wear into cone, the axial force generated by while working out.
4 slide shift fork shaft, pin and other parts wear too large, fork bending deformation or face gear with ring groove grinding.
Second 5 shaft rear fixed nut loose, resulting in second axial movement of the shaft.
6 synchronizer locking pin loosening or breaking, cone failure.
When a file is found out, the gear shift lever is pushed into the file, and then remove the North V3 parts transmission cover, see the gear meshing. If the gear meshing is good, then the fault in the gear shift mechanism. Positioning device by hand pushing the shift fork test of the gear shift fork. If the location is bad, need to remove the shift fork shaft, ball and spring inspection. If the gear is not fully engaged, with hand push off gear gear or gear sets, proper meshing, should check the shift fork is bent or grind open, shifting fork fixed screws are loose, the end of the fork and the gear groove clearance is too large. If the shift is good, while the gear or gear sets and fully engaged, should check whether the tapered gear, bearing is loose, transmission shaft is moved back and forth. According to the problems found in the above inspection, according to the standard repair, if necessary, replace the new parts, in order to completely eliminate the chaos and off the block fault
