Installing a clamp allows you to avoid leakage of the embedded lubricant. During operation, the CV joint clamp may become loose and debris trapped under the boot will soon cause a crunch and the need to repair the joint, so at the first release of lubricant, measures should be taken to prevent depressurization.

Plastic and wire clamps

Plastic clamps are not used to secure the boot. This is due to low strength and reliability of fastening. Such a clamp cannot withstand dynamic loads, and is also prone to damage from high and low temperatures.

Properly placed wire clamp does not differ in fixation strength from the factory one. Despite this, its use is not recommended for the following reasons:

• too much tightening leads to cutting the boot;
• the wire may not be rigid enough, which will lead to loosening of the fastening;
• lack of strength causes the wire to break during operation.

Unlike plastic, a homemade wire clamp can serve as a temporary replacement for the original. Should be replaced as soon as possible this mount to a more reliable one.

Band metal clamps

Most often this type The fasteners are included in the factory configuration. This is due to reliable fixation and ease of installation. In order for the CV joint clamp to be used for a long time, the following conditions must be met:

• when making the tape, the manufacturer used high-quality steel;
• installation on the boot was carried out using a device for tightening CV joint band clamps;
• To install fasteners, you must have skills in using the tool.

To tighten the CV joint clamps, you can use improvised means, but the quality in this case will depend only on the experience of the craftsman. The only tool you need is pliers. Sequence for tightening the clamp:

1. The clamp fits onto the boot;
2. The tip is grabbed with pliers;
3. Pull with a little force and make sure that the clamp tightens the boot without distortion;
4. Create maximum force and bend upward;
5. Bend the antennae;
6. Fasten the end of the ribbon.

Upon completion of installation on the constant velocity joint, it is necessary to check the uniform fit of the clamp and the absence of distortions.

Using special devices when installing a band clamp

To simplify tightening the tape and improve the quality of fixation of the boot, a special tightening machine is used. Its design includes:

• pen;
• holder;
• pinwheel.

To use the device, you should follow the plan:

1. Place the tape over the boot;
2. Insert its end into the cut of the holder;
3. Place the holder against the clamp lock;
4. Using rotational movements, begin to wind the tape onto the tool;
5. With sufficient tension, bend the tape;
6. Check the fastened clamp for correct installation.

To implement high-quality installation the final force must be determined correctly. The tightening force should not allow the grease to come out, but it should not allow the boot to cut.

Clamp fastener

Some European-made cars have switched to using clamp clamps, as they combine reliability and simplicity. To install them, special pliers for CV joint clamps are used.

Placing the clamp on the CV joint occurs in the following order:

1. The required diameter is selected;
2. The clamp is located on the boot. It should be installed without distortions;
3. To perform crimping, clamp pliers are used. If they are unavailable, you can use pliers of a suitable size;
4. Upon completion of work, you should check the reliability of fixation of the clamp.

The main advantage of clamping fasteners is that there is no need to purchase expensive special tools. Carrying out the work with conventional pliers will ensure high reliability and long service life.

Alternative options

You can also secure the CV joint boot clamp using a screw clamp. You can use a wrench or a screwdriver to tighten it. It practically does not require any skills to fix it, but it has a number of disadvantages that do not allow it to occupy the niche of clamps for CV joints:

A temporary alternative placed on the CV joint can be a screw clamp with a key. Its installation can be done on the road to ensure that the lubricant is not contaminated when traveling to a service station.

When choosing between a band clamp and a clamp clamp, you should be guided by your preferences and the manufacturer’s recommendations. They both can last a long time correct installation. Care and accuracy when installing any of the fasteners will allow the lubricant to remain clean for a long time.

This is probably in the mentality of a Russian person - tighten the clamps so that the hose is squeezed out from under it, make two turns of the tape clamp on the CV joint boot, when just one is enough, if you press the button, then so that it crunches, twist the nuts - bolts on the wheels - be sure to jump on the tire, in case it comes loose on the road! And so it is everywhere. Constantly overdoing it. I think this is all stupidity. Yes, exactly from her. And also from the inability to think logically. A logically thinking person, as well as a seeing person, will see that both on the shaft and on the “grenade” itself there are ring grooves into which the edges of a correctly selected boot fit clearly. That is, the boot sits on the grenade and the shaft WITHOUT any clamp, and if you do not subject this boot to mechanical stress, then the lubricant will never leak from it even WITHOUT a clamp.
For those who have not yet understood: The clamp on the boot serves only to support the boot, that is, this clamp SHOULD NOT be tightened tightly, it should be tightened loosely enough so that it just begins to bend the rubber under it. And when the boot comes off, and when the horseradish squeezes out from under it. The boot is held in place by a groove. and is compacted by the very elasticity of the rubber. The clamp is needed, I repeat, only for support, to prevent the boot from jumping off the groove under accidental mechanical impact.
So take pliers and a screwdriver. Make ONE turn of the clamp. We use a screwdriver, use pliers to tighten the clamp with the effort of a weak granny, bend it, cut off the excess, leave the tail 0.3 cm so that it doesn’t get caught on anything, then hit it with a hammer, flatten it and that’s it. There is no need for any filigree wrapping of the tail; fixing it under the mustache is also unnecessary. This very minimum 0.3 cm and a hammer blow are enough. The clamp appears to be solid, nothing sticks out, and therefore there is nothing to catch on.
And one more thing: The boots must be put on a dry shaft, without any lubrication. That is, everything should be dry under the rubber. These are YOUR problems, how to fill the CV joint so as not to smear it seats boot, but they must be clean.

To transmit engine torque from the gearbox to the drive wheels without loss of power, a constant velocity joint (or CV joint) is used. This part is used both on rear-wheel drive cars and on cars with front-wheel drive. It is secured with clamps. This article will tell you how to properly tighten the clamp on a CV joint.

Why attach a clamp to a CV joint?

The CV joint is a reliable mechanism that can travel more than 150,000 km without problems, but over time it becomes unusable. An unpleasant crunch indicates problems with the part. Not only used cars, but also brand new cars can crunch. The ability of a hinge to serve faithfully for a long time depends on 2 conditions:

• complete lubrication;
• defence from negative influence environment (pollution or water ingress).

The hinge needs to be lubricated - and the more often the better. And it is protected with the help of a boot, which is put on the shaft and reliably covers the elements of the assembly. The boot is secured with clamps. When they weaken, you hear unpleasant sound. Therefore, from time to time the driver is faced with such a task as tightening the CV joint boot clamps.

There are several ways to attach a CV joint:

• belt mechanism;
• clamping fastener;
• U-shaped mounting option.

How to tighten a band clamp on a CV joint - manual method

Installing such a device is not difficult, and its fixation is quite reliable. When choosing a device, look at the quality of the steel from which it is made. To fasten it, you will have to use a device for tightening the ribbon clamps. You can use pliers to tighten the device.

We proceed like this:

• We place the clamp on the boot, and grab its tip with pliers.
• Next, pull the tip towards you, applying effort. During the procedure, we ensure that tightening occurs without distortion.
• We move the tip up a little and bend the antennae.
• Fasten the end of the ribbon. Upon completion of installation, check the uniformity of fit.

Here's how to properly carry out the procedure using a tightening machine:

• We place the tape on top of the boot. We insert its tip into the holder (there is a cut for this).
• We press the holder to the clamp lock.
• We wind the tape onto the tool using rotational movements. When the tension is normal, bend the tape.
• We monitor the installation. Consider the tension force. After tensioning, no lubricant should come out. If you overtighten, the boot will burst.

How to tighten a clamp on a CV joint - mechanical method

Some cars from Europe have switched to using clamps made in the form of clamps. The clamps are simple and durable. They are usually installed using pliers, but craftsmen also make do with ordinary pliers.

Before installing the clamp, you need to select the diameter. After this, the clamps are installed on the CV joint boot. It is important to avoid distortions. Installation is best done using crimping pliers. If they are not available, we use pliers. The work is not difficult; upon completion, you need to check the quality of the clamp. The main advantage of this option is that you do not need to use special tools. If you use regular pliers when installing the device, the quality of the clamp will not suffer.

A screw type device can be used. It is clamped with a screwdriver. This type of clamp is the easiest to install, but it has its drawbacks:

1. The “grenade” (slang for a hinge) is subject to vibration, which can cause the bolt to come loose. Therefore, you need to tighten the device as much as possible.
2. A protruding lock looks unsightly. In addition, when driving, it may hit something.
3. Such clamps are often of poor quality.

How to tighten the boot clamp of a U-shaped CV joint

Now covers have begun to be made from a harder material than ordinary rubber. They can be difficult to tighten using ordinary band clamps. Therefore, many car enthusiasts prefer modernized devices. There are different options, among the inexpensive ones are fasteners with U-shaped ears. They are tightened with pliers, most often of the Licota ATC-2190 brand.

These pliers are quite expensive - up to 20 euros, but there are cheaper options. It is better to use pliers with a 1/2 square cutout. The handles on them can be extended using knobs. The principle of operation of the device is simple: it compresses the U-shaped tubercle on the clamp, and the fastener is well tightened. Tools with long handles are especially effective. They even compress well covers made of dense material.
