On the way of driving, there will always be such and such situations, which may cause certain economic losses in light, and affect life safety in the worst case. So how to avoid such emergencies? It is also necessary to conduct frequent inspections, so as to detect and deal with them in a timely manner.
For example, it is found that the clutch of the truck does not disengage during driving. I don’t know if you have encountered this situation. Let’s analyze it together to see what factors cause the clutch of the truck to not disengage and how to deal with it.
1. Check the brake oil in the clutch oil casing to see if the oil is too low. If the oil is too low, of course it cannot be used. If the oil level is normal, step on the clutch a few more feet on the car to see if the gear shift is improved. If there is any improvement, air is mixed in the clutch oil circuit. At this time, exhaust the air and try again.
2. Check the clutch master pump and clutch sub-pump to see if there is oil leakage around, if there is oil leakage, it is necessary to replace the oil-leakage sub-pump or master pump.
3. Whether the clutch master cylinder or sub-pump is not tightly sealed, if not, a single replacement of the repair kit generally cannot guarantee the quality, and the above failure may occur again after a period of time. In this case, it is recommended to replace the assembly.
Find out the reason and know how to deal with it, but there may be doubts about the actual operation. Below we will explain in detail how to discharge the air in the clutch oil circuit.
It takes two people to discharge the air. You can ask the same car for help. One of them slams on the clutch and holds it down after a certain number of times. Then repeat the step and discharge process until the clutch feels high and no air bubbles can be released from the air release screw, and then lock the air release screw. At the same time, check the free clearance of the shared push rod of the clutch cylinder and the master cylinder. Generally, it is about two to three millimeters, and it can feel a little gap.
Wipe off the oil stains, get on the car and step on the clutch to shift the gear, and see if the clutch is separated normally, the gear shift is smooth and there is no slap in the teeth, and if there is any other fault, if the clutch separation is normal, the fault is solved. Of course, if it is necessary to replace the assembly, it must be handled by a professional repair factory.
