Remover for ball bearings: description and types

Carrying out the repair of the steering system and the chassis of the car, the owners are often faced with the situation of dismantling ball bearings and tie rods. These structural parts can not be removed without a special tool. This is a puller for ball bearings. The device is capable of several times simplifying the process of extrusion of parts.

To buy this tool is not difficult - just go to the nearest auto parts store and choose a suitable puller there. You can also make a device yourself. Consider the types of pullers, and also talk about the selection of these tools.

Types

The modern market of tools for servicing and repairing cars offers the widest selection of different pullers, including several types of tools for dismantling ball bearings and steering rods. The puller for ball supports can be:

• Screw.
• Leverage.

The first devices are considered a more universal solution. They are suitable for servicing any cars.

Screw puller

The force in this mechanism is created by screwing the bolt into the body. The tool body itself is put on the eye in the ball joint. In the process of tightening the bolt, it rests against the finger. The latter is pushed out of its landing nest.

Leverage

Equally effective is the lever puller for ball bearings. However, these tools are large in size. Therefore, not for every car. For example, with a lever tool on the VAZ-2107, the top ball joint can be dismantled, but it will not be possible to remove the lower one - the working space is too limited. For this, it is best to use a special tool. The lever puller is two connected to each other in the middle of the lever. On one side there is a hole in them. This is where the tightening bolt is installed. For dismantling, it is required to install one tool lever between the ball joint and the eyelet, and the second - under the finger. In the process of unscrewing the bolt due to the connecting axis, the two ends of the levers will converge. The finger will begin to be pushed out of its seat.

Such a device can not be purchased - it is easy to make a puller of ball bearings with your own hands. It is collected from improvised means. Let's look at other tools that you can both buy and make yourself.

Wedge

This is the most simple and yet quite effective puller. It can not be attributed to any type of mechanism, however, in matters of molding it is a good choice. For the manufacture you will need only a Bulgarian or a machine with an abrasive wheel. The workpiece is a plate of metal, the dimensions of which are similar to the box of matches. At the beginning, the metal platinum is shaped into a so-called wedge-the metal is soiled that the shape of the part in the profile is triangular. Then the Bulgarian or with a machine tool in the middle make a cutout. Its length should be about 2/3 of the plate. The cut is made from the thin side. The width of the cutout is made larger than the thickness of the support on the finger. The result should be something like a brace.

Then a rod is welded to this bracket. With it you can use a puller for ball joints. Working with a wedge is easy enough. It is installed in the gap, which is between the eye and the body of the ball pore. Then, using a hammer, the wedge is clogged, which results in the pressing out of the finger.

But when working with this tool there is a significant drawback. In the process of pressing out the support, the anther is damaged. That is why the wedge is used only when replacing the tips or supports. It is better to refuse repairs with such a device.

Screw Expanders

This is another option that you can make yourself. He proved himself well as a stripper of VAZ ball joints (concerns classical models). The design features of the suspension system of these machines are such that both the upper and lower supports are installed symmetrically to each other. There is not much distance between them. The mechanism can be manufactured only with a drill unit. The device consists of two parts. For production, a hexagonal or square bar is required. The diameter is 17 or 19 millimeters. In the rod make a hole and cut the thread M8. Then it remains to screw in the bolt - and the tool is ready.

Consider how this stripper removes ball joints. VAZ-2107 can also be repaired. To disassemble the upper support, unscrew the lock nut, however not completely. Then, between the fingers, a puller is installed with a fully twisted bolt. Then hold the device with two keys. Twist the bolt until the finger comes out of the socket. After the upper support is replaced, the same operation is performed on the lower one.

L-shaped screw puller

For which cars can this stripper stripper be used? 2107, 2105 and 2106 - these are the cars of the brand VAZ, for which it fits best. The tool is versatile enough. To make it, you need a rod made of metal - its diameter should be at least 10 mm, and length - 15-17 cm. This rod makes a L-shaped workpiece, the length of the shoulder of which should be at least 5 cm. So, take a rod, Measure on it 5 cm, clamp in a vice and bend at a right angle. On the long part of the element, the thread is cut. Find a suitable nut.

Now you need to make a stubborn bar. It is made on the principle of a wedge. For the workpiece is suitable plate, the thickness of which is not less than 5 mm. On one side, the plates make a slot that fits over the support pin. On the other - make a hole for the diameter of the rod. Next, put the plate on the long part of the rod and clamp the hare. This puller works as follows. The nut is twisted as far as it will go, the plate is inserted into the gap between the eyelet and sometimes. The rod is rotated in such a way that the short part of it rests against the finger. Then the nut is twisted. The plate works as an abutment, and the rod extrudes a finger.

Screw puller from corner

This puller of the steering ball joints is made from a corner by welding. How to make it? Take a corner, the length of which is 7-8 cm. The thickness of the metal can be 3-5 mm. In one side of this corner, they make propyl. With the help of it the mechanism will be held on the eyelet. Three triangular pieces are cut from a steel sheet 3 mm thick. They are welded on the sides to the blank-corner to increase the strength of the structure. Next, take a nut 17 mm and a bolt for it. The nut is welded at right angles to the slot in such a way that the hole looks at the cut. To bolt easily located on one axis with a finger, on the corner before welding nuts set spacer. To use the device, just screw in the bolt.

Do or buy?

Removers of ball-point ferrules for domestic cars do not cost more than 1000 r. You can buy the device in any store. Hence, it turns out that the tool is easier and easier to acquire. To produce even the most simple tool, you need blanks, special nuts and bolts with a large thread pitch.

It is easier to acquire a finished instrument and because it saves time. You do not have to do extra work. Perhaps buying a device and will cost a little more, but then there is no need to waste energy and time on making tools.
