Tires removed, half axles.

Fixing at one end.

The screws are removed, the triangular fixing screws of the lower limb arms are unscrewed, the end screw of the half-shaft gearbox is removed, and finally the fattalanche can be replaced;

Remove the half-shaft rose, pull out the half-shaft, and then you can see the oil seal, dig it out, and then replace it;

The half-shaft oil seal is located in the lower part of the chassis, and the function of the half-shaft oil seal is to close and divide the two places of the drive axle and the wheel side reducer, and the half shaft is used to transmit the output torque of the differential half-shaft gear to the drive wheel or the wheel side reducer.

To change in the car, you need to remove the half-axle assembly. Use a screwdriver to buckle the flange plug cover. Remove the inside card and remove the flange to better the oil seal.

If you often have to disassemble and assemble, it is recommended to make a special tool, which is very easy to use. If you haven't seen it, I'll describe it first, and I'll draw it for you if I don't understand. Take the old half shaft, remove the bolts, make a large cylinder with iron, about 20-30 pounds, the diameter of the hole in the middle is slightly larger than the half shaft, just let the half shaft go in, and then weld the other end with a round iron block.

That's pretty much it.

How to use: Use the end that you just removed the bolt to put on the half shaft of the car you want to repair, fix it with a nut, then toggle the large cylindrical iron block, pull it back, touch the end of the iron block you welded on, use the shock force, and the half shaft will come out. Pay attention to the welding must be firm!

Park your car on a flat level.

Pick up neutral and release the brakes.

Remove the half-shaft screws.

Jack up. Hit the half shaft around with a hammer.

Then aim at the middle of the half shaft, smash it down with medium force, and use the ** force half shaft will generally pop out.

1 Jack up the two rear wheels (generally top the rear pressure pack), 2 Remove the tires 3 Remove the brake pads and oil hose as needed, 4 Remove the internal fixing screw caps or screws of the half shaft, generally 4. 5 Flip the wheel hub and install it, and use the hammer to knock it outward appropriately, and it should be able to take it out under normal conditions 6 It really doesn't work, you can install the tires, hit it with a larger hammer, and try. 7 Replace the oil seals and check the bearings and spacers for wear.

Propeller shafts are not.

Oil seal, if the drive shaft in front of the gearbox oil seal leakage, behind the drive shaft is the tail tooth before the oil seal leakage, with the change process, a removal of the drive shaft if the gearbox after the oil seal leakage, then find a word knife directly warped out to get wiped clean and install a new one, install a new oil seal, pay attention to the oil seal edge of the spring out of the edge of the oil seal cut off 2 mm.

If you have a tool, it's easy to change. Remove the tires, loosen the half-shaft bolts, remove the lower swing arm and directional tie rod, pull the half-shaft out of the differential, skid out the oil seal, put the new one on, and then put the removed thing on and it's OK. Hope it helps, thank you!

Car questions, ask the car guru. 4S shop professional technician, 10 minutes to solve. 】

How to change the oil seal of the automobile crankshaft, there are the following points:

1. Take a look at the oil drain bolts, whether they are loose, tighten all the screws at the connection between the oil pan and the crankcase, there is an oil seal in the middle, if the screws are loose, the oil is very likely to leak from here. Then tighten the connection between the valve and the cylinder head above, where there is also an oil seal. This should be the solution to the world's brother.

2. The crankshaft oil seal does not use non-petroleum-based lubricant in the press-fitting process, resulting in the loosening or even falling off of the oil seal after the engine is used for a period of time;

3. The parallelism of the rear oil seal pressing surface for the installation surface of the rear oil seal seat does not meet the technical requirements of the assembly drawings, which makes the rear oil seal lip unevenly deformed by the force, and the oil seal lip is deformed and even the entire oil seal is distorted after the engine is used for a period of time, resulting in oil seal damage and oil leakage.

4. The service life of the dust side machine is long, and the natural aging of the oil seal causes cracks at the lip of the oil seal, resulting in oil leakage.

Hope it helps!

Automobile crankshaft oil seal is divided into crankshaft front oil seal and crankshaft rear oil seal, if the crankshaft front oil seal is replaced, the engine belt needs to be removed. Crankshaft pulleys. Replace the crankshaft front oil seal.

If the more wild sail change the engine. Crankshaft rear oil seal, which requires the gearbox to be lifted. Replace the crankshaft rear oil seal.

When replacing the oil seal. Use a screwdriver to pry the oil seal out, and then find a suitable mold for the new oil seal and gently smash it into it with a hammer. Silly slate the oil seal with grease.

What do you do when you install it?

How to replace the half-shaft oil seal The replacement process of the half-shaft oil seal is very simple, first remove the half-shaft assembly, use a screwdriver to buckle the cover of the French cave, and then remove the card inside, and then remove the flange to replace the oil seal: 1. The half-shaft is used to transmit the output torque of the half-shaft gear of the differential to the drive search vertical wheel or wheel trembling side reducer; 2. The oil leakage of the half-shaft oil seal will reduce the amount of lubricating oil in the drive axle, which will affect the normal lubrication, and will aggravate the wear of the parts, resulting in early damage; 3. If the half-shaft oil seal leaks, the lubricating oil will flow into the wheel reducer, causing the oil level of the wheel reducer to rise, flush the oil seal, and flow into the brake drum, causing poor braking and affecting safety. @2019

Half shaft oil seal is one of the important components in the automobile engine, its function is to prevent oil leakage, protect the engine to run normally. When replacing or installing half shaft oil seals, be sure to pay attention to the following steps:

1.Cleaning work: Before installing the half-shaft oil seal, the half-shaft and the oil seal seat should be cleaned first, so as to avoid the oil seal being damaged by dirt or foreign matter.

2.Lubricant: Apply a certain amount of lubricant to the inner and outer rings of the half-shaft oil seal for better installation and to prevent damage.

3.Installation position: Gently insert the half-shaft oil seal into the oil seal holder, and make sure that the inner and outer rings of the oil seal are tightly attached to the surface of the half-shaft.

4.Use installation tools: When installing half shaft oil seals, special installation tools can be used to avoid damage to the oil seals.

5.Inspection: After the installation is completed, carefully check the installation position and sealing effect of the half-shaft oil seal to ensure that there is no leakage.

In short, the correct installation and maintenance of the half-shaft oil seal is very important for the normal operation of the engine, which requires us to operate carefully during installation to ensure that each step is correct to ensure the long-term stability and reliability of the engine.

Hello, filial piety, you have changed the oil seal skeleton, right, if the flywheel moves the position, you can't install it. If it happens to be a good belt alignment, the small eye on the gear ring inside the oil seal after curving can be aligned with the small column in the lower right corner of the oil seal frame. Installation Method:

l) To adjust the contact clearance of the breaker, the contact clearance of the breaker should be adjusted first. Because the size of the contact gap of the breaker not only affects the strength of the high-voltage spark, but also affects the ignition time. When the contact gap of the breaker is large, as soon as the cam is in contact, the breaker contact is opened, the ignition time is advanced, and the closing time of the breaker contact is shortened, so that the primary current is reduced, the secondary voltage is reduced, and the spark plug spark is weakened.

On the contrary, the contact gap of the breaker is small, and the ignition time lags. 2) Place the first cylinder alive.

2. A brief introduction of the crankshaft: The main rotating parts of the engine, after the connecting rod is installed, can undertake the up and down (reciprocating) movement of the connecting rod into a cyclic (rotating) motion. It is an important part of the engine, and its material is made of carbon structural steel or ductile iron, and there are two important parts:

Main journals, connecting rod journals, (and others).The main journal is installed on the cylinder block, the connecting rod journal is connected with the connecting rod big head hole, and the connecting rod small head hole is connected with the cylinder piston, which is a typical crank slider mechanism. The lubrication of the crankshaft mainly refers to the shaft with the connecting rod and the big head.

3. Illustration: More than 90% of the oil leakage problems of GDW765 are due to the rubber sealing ring inside the gearbox being subjected to cold and warm temperatures for a long time.

Hello! This still needs to be replaced by professionals, first of all, we must find a good manufacturer, so that the oil seal is replaced to prevent oil leakage.

Pro, the half-shaft oil seal usually needs to remove the spring when it is installed, and then install the spring back after installation. But if you don't want to remove the spring, you can do it as follows:1

Clean the new half-shaft oil seal in detergent or gasoline to ensure that the surface of the oil seal in contact with the half-shaft is smooth and defect-free. 2.Lightly coat the half shaft with some lubrication to make it easier to slide into the half shaft oil seal.

3.Gently push the half-shaft oil seal into the half-shaft hole along the axial direction of the half-shaft, taking care not to use excessive force to avoid damaging the oil seal. 4.

Make sure that the position of the half-shaft oil seal is correct, and use the appropriate tools to install it in place. 5.If you wish to insert the spring into the half-shaft oil seal after installation, you can use a slender tool, such as a small screwdriver or a thin wooden stick, to compress the spring little by little and gently push it into the half-shaft oil seal.

However, it should be noted that this method may be more difficult, the operation difficulty is greater, and the assembly effect may not be as good as when the spring is removed for assembly. Therefore, it is advisable to use this method in extreme cases.
