Hello, I have a question to ask you, what is the matter with the fifth gear of the truck

From what I know about the mechanics of automobiles, if your truck is in fifth gear, your gearbox is faulty.

The highest gear is the five-gear vehicle, we call the five-gear direct gear, when the car is in normal driving, this gear is the most commonly used and most economical gear, the working condition at this time is that the input shaft of the transmission (also called a shaft) is directly connected with the output shaft (also called the second shaft), and the fifth gear will not be converted through the intermediate shaft when working. Therefore, once your gearbox jumps, it is generally the middle bearing of one shaft that is damaged.

The procedure is to hang the tooth box, check the fault after opening, and then remove the shaft, the fault will be quickly eliminated and the maintenance operation will be completed.

What are you talking about, is the spring that sets the gear or is broken, to put it bluntly, it is to hang the gear, the pin spring pressure is small or there is no pressure, and it can't be stuck, thank you.

It's so thunderous! One is lower than the other, but the higher level is wrong.

I don't know your model, no matter how you ask, you have to disassemble the transmission.

Or after disassembling the transmission, check which one is broken and replace it.

A car is a complex mechanical assembly, and with the use of time, it is inevitable that some problems will arise. The fifth gear is often out of gear after being hidden and often out of gear is a problem that many drivers will encounter during driving. There are many reasons for this failure, and the specific reasons are as follows:

1. The transmission gear and synchronizer are seriously worn and cannot maintain normal operation.

2. The gear locking device of the transmission is damaged and the gear cannot be locked normally.

3.The transmission lever connection is loose and very loose.

4. The transmission lever is deformed.

The easiest repair method is to get out of gear in five gears as follows:

1. If the five gears are out of gear due to the wear of the transmission gear and synchronizer, they can be replaced as long as the gear and synchronizer are worn excessively.

2. The transmission gear locking device is damaged, which is generally a fork shaft problem, at this time, it is necessary to check the fork shaft maintenance, and solve the problem to solve the five-gear out-of-gear.

3. If the five gears are out of gear due to the loose connection of the gearbox operating rod, the corresponding operating rod needs to be replaced.

4. The deformation of the transmission shift fork also needs to be replaced.

From the above, it can be seen that there are many reasons for hanging five gear jumps, so the maintenance of ** is not a fixed value, and it can be solved within 1000 yuan. Of course, if the car is more expensive, **will**.

Car owners should also pay attention to the maintenance of the gearbox during daily use, and can regularly replace and replenish the gearbox oil to keep all parts of the gearbox in the best working condition. When choosing a transmission oil, you should choose the right viscosity to better reduce the wear and tear of the parts.

Also, do not push the gear lever too hard when shifting gears. At the same time, the correct and reasonable use of each gear, such as when the load is not high, when the fifth gear is running at high speed, reduce the gear wear rate.

In the actual driving process, the correct way to shift gears is to upshift when the speed reaches 2000-2500rpm, and the stool should be accompanied by upshifting, rather than stepping on the accelerator, which will not only increase fuel consumption, but also easily aggravate engine wear, and the speed is low. Downshifts should be lowered below 1500rpm, otherwise the engine speed is too low and the load is too large, and it is easy to die.

The gearbox has been damaged, the gear has been run-in, the lever is deformed, the lever is loose, and the wear and tear of the gear cover is more serious.

There was a problem with the driving speed Sun Liang, the gear of the manual transmission was not hung up, and there was an accident of filial piety when driving, or a problem with the car, and a problem with the car's cautious driving.

Speed is very important, there is no way to properly hang the gear, and the car is driven by the model relationship, the quality of the problem, and the road surface is related, and the surrounding environment is related.

The gear was not properly hooked, there was a problem with the gear, the gears were worn, the gearbox was loose, and the gear lever was faulty.

The 4-gear off-gear should be analyzed according to the situation:

If there are only four gears off, and the other gears are normal. That says gearbox.

There was a problem with the internal four-speed synchronizer, and the friction of the coarse gear ring of the synchronizer was seriously slippery, and this required dismantling the gearbox and replacing the synchronizer.

If all gears have the phenomenon of disgearing, it is not a problem inside the gearbox, but the control mechanism between the gear lever and the gearbox, and the self-locking steel ball of each gear.

Manual pin bird town car gear introduction:

1st Gear: Used when starting normally or climbing a very steep slope. With this gear, the speed is generally 10 km/h;

2nd gear: used to accelerate in excessive gear after starting, or when advancing at low speed or climbing steep slopes, the speed is generally 20 kilometers per hour;

3rd gear: generally used at a speed of 20 kilometers to 40 kilometers, and this gear is often used when driving in urban areas;

4th gear: when the speed is 40-60km h, this gear can be used;

5 gears: This gear can be used at a speed of more than 60 kilometers per hour, and it can be used when the vehicle is running at high speed;

N gear is neutral.

It is used when parking and idling, such as waiting for a traffic light, when hanging to N gear and pulling the handbrake.

R gear is a reverse gear, and it is put into this gear for reversing after the vehicle has come to a standstill.

On the one hand, there may be a problem with the spool valve box, and if you are covered, you can claim it.

On the other hand, it is caused by bad driving habits, is it very gentle to drive at ordinary times, and you can not step on the accelerator without stepping on it? Drive the cheerleading high-speed and run each gear for a while! If it is convenient, go to the 4S store to reset the data.

This situation will occur in the old models, affected by the design level at that time, the 4-speed transmission, there is no synchronizer, so it is easy to get out of gear, and the five-speed transmission designed later, there are synchronizers, so this situation is rare.

If you use 4-speed off-gear, replace the 4-speed synchronizer and 4-speed synchronous ring, and check the 4-speed gear along the way.

Fourth, if you are out of gear, it may be because there is a problem with your gear lever. Or maybe it's because I'm too fast and too slow.

The fourth-speed self-locking screw, also replaced, why doesn't it work? Or is it a shift change?

This situation may be a problem with the initial processing of the synchronizer.

How much is Dongfeng Fengxing Lingzhi M3 five-gear gear?

Summary. Hello dear!! We'll be happy to answer for you.

The reason for the frequent disgearing of the automatic transmission of Jiefang truck is due to the wear and loose damage of the relevant parts of the transmission, or the improper adjustment of the matching clearance. The analysis of the reasons for shifting gear is as follows: 1. The gear lever positioning pin is worn loosely, broken or lost, so that it loses control and swings arbitrarily.

2. Abrasion failure of variable speed fork shaft interlock device; The gear lever ball joint is too worn and loose. 3. The gear, ring gear or sleeve is worn into a conical shape in the direction of the tooth length, and is out of gear due to the axial force generated during work. 4. The gear shift fork shaft chute, lock pin and other parts are too abrasive, and the fork is bent and deformed or the working face and the gear ring groove are abrasive.

5. The fixing nut at the rear end of the second shaft is loose, resulting in the axial channeling of the second shaft. 6. The locking pin of the synchronizer is loose or scattered, and the cone surface fails.

Hello dear!! We'll be happy to answer for you. The reason for the frequent disgearing of the automatic transmission of Jiefang truck is due to the wear and loose damage of the relevant parts of the transmission, or the improper adjustment of the matching clearance.

The analysis of the reasons for the shift is as follows: 1. The gear lever positioning pin is worn loosely, broken or lost, so that the slag is lost and swings arbitrarily. 2. Abrasion failure of variable speed fork shaft interlock device; The gear lever ball head is too worn, loose and simple.

3. The gear, ring gear or sleeve is worn into a conical shape in the direction of the tooth length, and is out of gear due to the axial force generated during work. 4. The gear shift fork shaft chute, lock pin and other parts are too abrasive, and the fork is bent and deformed or the working face and the gear ring groove are abrasive. 5. The fixing nut at the rear end of the second shaft is loose, resulting in the axial channeling of the second shaft.

6. The locking pin of the synchronizer is loose or scattered, and the cone surface fails.

It's an automatic transmission, not a manual one.

The reasons are as follows: (1) the elastic force of the fork spring is weakened or broken, so that the self-locking position fails; (2) The fork locking screw is loose, and the steel ball of the fork shaft positioning groove or the cover is worn out, and the gear lever cannot be reliably positioned; (3) The effective stroke of the fork contains small objects or the fork is bent and deformed, resulting in the gear meshing is not in place, and it is easy to get out of gear after being stressed; (4) The end face of the fork is seriously worn, the gap between the end face of the fork and the groove of the sliding gear ring is too large, and the sliding tooth wheel is easy to shift forward and backward and automatically disengage; (5) The gear working surface is worn into a conical shape, so that the gear meshing gap is too large, and the axial thrust is easy to be generated, resulting in the sliding gear disengaging and meshing;

It will not be out of gear during driving, it will become neutral after parking, and it will not go after stepping on the brakes.

Kiss. You check the above for your question. See if the problem is still there.

There is no other reason.

Kiss. Nope.

You can have a look at the working schematic diagram of the automatic transmission of the liberation car.

Is this a tractor's.

Kiss. It's not.

Hello, as a complex mechanical aggregate, the car will inevitably have some problems with long-term use. Five-gear off-gear is a problem that many riders will have during driving, and there are many reasons for this failure, and the specific reasons are as follows:

1. The transmission gear and synchronizer are seriously worn and cannot be kept working normally.

2. The gear locking device of the transmission is damaged, and the gear cannot be locked normally.

3. The transmission control rod is not tightly connected and very loose.

4. The transmission lever is deformed.

The easiest repair method for five gears to get out of gear.

1. If the fifth gear is out of gear caused by the wear of the transmission gear and synchronizer, just replace the excessively worn gear and synchronizer.

2. If the gear locking device of the transmission is damaged, it is generally a problem with the fork shaft, so it is necessary to inspect and repair the fork shaft to solve the problem and solve the problem to solve the five-gear offshift.

3. If the five-gear shift is caused by the poor connection of the gearbox operating rod, the corresponding operating rod needs to be replaced.

4. The deformation of the transmission fork can only be replaced.

Riders should also pay attention to the maintenance of the transmission in the process of daily car use, and can regularly replace and add transmission oil to keep all parts of the transmission in the best working condition. When choosing a transmission oil, you should choose the right viscosity, which can better reduce the wear of the parts. Also, when shifting gears, don't use too much force to move the shift lever.

At the same time, it is necessary to use each gear correctly and reasonably, such as not driving at high load and high speed in the fifth gear, so as to reduce the wear rate of the gear.

Hello, no, the gear off is a problem with the self-locking device of the gear mechanism inside the transmission, and the transmission needs to be disassembled, hope.
