Homemade pullers for removing shock absorber strut springs. A device for quick disassembly of racks, replacement (compression) of the spring on them. What you need to know when dismantling

When repairing or adjusting the suspension of a car, it becomes necessary to fix the spring in a certain position.

For these works, there is a service device: a spring puller, with which you can remove the chassis elements both in a specialized workshop and in garage conditions.

Various tool concepts:

Let's consider the second option in more detail.

How does a spring puller work, and what are they?

What is a puller for? It overcomes the straightening force of the springs. The applied force on the puller arms is commensurate with the weight of the car, but this does not mean that its design is too expensive and high-tech.

There are many options, but they are divided into only two types: mechanical and hydraulic drive.

Mechanical spring extractor

Most often it has a threaded drive mechanism.


With a sufficient diameter of the stud (providing a good gear ratio on the thread), and a long wrench handle, it is possible to compress the springs manually without excessive force.

The technology is as follows: two pullers are symmetrically put on the rack. By turning the threaded stud, you bring the grips to the middle of the spring right on the shock absorber, compressing it to the required size.

Important: Why can't the mechanical puller be used alone? When compressed, the spring bends, it is impossible to control this process.

Installing one puller on the spring will break it

Pullers fitted on both sides ensure uniform compression. When working with the suspension of trucks or heavy SUVs, experienced craftsmen install 3 or even 4 pullers.

Correct installation spring pullers

Semi-fixed racks

Service stations often use semi-permanent struts to remove springs from shock absorber struts.

The tool is quite versatile, suitable for most pendants. Thanks to the gearbox of the drive mechanism, it is convenient and safe to work with it.

The only drawback is that it is not always possible to compress the spring directly on the car. Still, this is a bench device: the puller works with the suspension removed from the car.

Popular: Do-it-yourself clamp facilitates the work of the master and saves him money

lever type

A similar "problem" with lever-type pullers. The mechanism is reliable and safe, but its dimensions do not allow crawling into the space under the wing of the car.

Hydraulic puller

Can be portable and stationary. It works on the principle of a jack: there is a main and working cylinder. By pumping liquid with the help of a lever handle, the operator compresses the power brackets, between which there is a spring.


A compact two-section puller can become an assistant in a home garage, but a floor-mounted stationary machine is only suitable for a car service.

The hydraulic system is pressurized with a foot lever. At the same time, the hands of the car mechanic are free, it is convenient and safe to work.

Of course, there are pullers with compressors, electric drive, and other devices that make life easier when servicing a car. All this is good until you see the price tag.

Sometimes it is more profitable to visit a car service several times than to purchase an industrial puller for personal use. Which exit? Make a tool with your own hands.

Making a shock absorber spring puller

Many car enthusiasts use a regular chain: wind a few turns around the coils of the spring, and tighten the chain. When the vehicle is jacked up, the suspension strut expands while the spring remains compressed. This is dangerous way CAUTION: If the chain slips, the unfolded spring could cause serious injury.

How to make a simple puller by analogy with an industrial one

A mechanical semi-stationary "machine" can be created from a "Volgovsky" jack.

Materials used:


Drill, grinder, file, welding machine- such a set is either in the garage, or available from a neighbor for a couple of beers. To the top of the jack (where the turntable with the gearbox is located) a platform is assembled from the corner. Then a bracket is welded to it according to the size of the support cup.

We fasten the connecting rod to the standard support lever of the jack, the shock absorber strut will go into it.


No need to worry about the strength of the structure. The jack raises the car, the connecting rod also withstands a huge load. And to strengthen the cantilever structure of the bracket, we weld the rods from the shock absorber rods.

The puller is universal: the length of the shock absorber allows you to service any racks for cars, as well as most SUVs.

The next spring puller, which is easy to do with your own hands, is a tightening type. Suitable for small sizes springs, since it is unrealistic to develop a large force on such a device.


Components are even more affordable than in the previous design. A piece of pipe, a corner and a long bolt M14 - M18. You can use a pin.
From the corner and sawn pieces inch pipe welding brackets. The puller consists of two identical ties, so there should be four brackets.


Be sure to weld the guide bushings for the stud. Otherwise, when tightening, the brackets will wedge.


The spring is compressed by synchronously tightening the nuts on the studs. If you use a set of 2 ties, they should be installed strictly symmetrically.

Every professional driver understands that a lot depends on the technical condition of the shock absorber. This includes the integrity of the body, the stability of the car, its ability to withstand heavy loads, comfort for passengers, etc. Therefore, shock absorbers need an eye and an eye. But what if they are out of order and need to be replaced? You can always choose this option, how to go to a service station, but this method is not for real car enthusiasts. It is worth trying to change it yourself, but for this you need a shock absorber spring puller. In this article we will tell you how to independently make such a device as a puller with your own hands and improvised materials.

Each car shock absorber has an external spring that is very firmly attached to the edges of the part. It also takes over the functions of protection against large particles and provides a small cushioning effect. Without strong springs, installing a shock absorber does not make sense, as it will be damaged very quickly. So the question is how to install and remove them.
The shock absorber remover helps the repairer to easily get rid of the springs and proceed to repair the main part or replace its protection. It can be either hydraulic (such a device can be sold in specialized stores) or mechanical (it can be made at home with your own hands).
The type of puller indicates the scheme of its work and the time to work with it. In other words, a mechanical puller will perform tasks more slowly and with the involvement of physical force, but does it really matter if we are talking significant financial savings Maintenance, replacement of shock absorbers and the purchase of a hydraulic type.

How to do it yourself

So, we decided that we really need a shock absorber puller, the only thing left is how to do it yourself? Here, the ability of each person to think and analyze logically should come to the rescue - what is unnecessary in the economy and what you can do.

When performing a puller, it is important to remember that it must be suitable for your car model and type of shock absorbers.

If welding parts is not a problem for you, then go ahead and make the part in this way, if there are strong extra jacks in your home arsenal, they can become an assistant, etc.

For example, consider how to build a shock absorber puller:

  1. We take a metal tube with a diameter of 18-22 millimeters and cut off 4 pieces of 15 centimeters from it, not forgetting to smooth the edges. This is important not for the structure itself, but for its safety. In addition, all work should be carried out with gloves.
  2. Then we cut off several pieces of a metal rod with a diameter of 10 millimeters, a length of 25-30 centimeters. There should be 8 identical pieces, after which we evenly bend one edge of the rod so that it has the shape of a one-sided hook. Please note that such a rod is very difficult to bend, so for this process it is better to use additional metal supports.
  3. We prepare four large M16 nuts or another size, depending on the chosen diameter of the future narrow tube or rod.
  4. Between two metal hooks from a rod we insert one piece of a cut pipe and weld this structure on both sides. Similar actions should be performed with the rest of the details. The result should be 4 small parts from the pipe and 2 hooks.
  5. Next, it is worth cutting the edges of the rod so that the part ends on the pipe, in other words, we align the part to the level of the tube.
  6. We measure the large shock absorber spring. It will be different for each car model, so immediately take yours, and from the front wheels. It is so important to do this because on the front wheels the shock absorber fails most often, since the front wheels take on all the load. Measurements should start from the first large coil and end with the last large coil of the spring.
  7. According to the measured size of the spring, we cut off two pieces of a narrow strong tube or rod with a diameter of about 1 centimeter and smooth the edges. The pipe must be very strong, you can take it with already prepared threads along a large part of the pipe. We put welded pipes with rods on each side of it and tighten it with a nut. Please note that it is also important to make a thread on a narrow strong tube so that the nut goes “like clockwork”.
  8. It is worth putting on welded hooks so that the rounded edge is external, and the ends look inside the spring.
  9. For structural strength, the locknut can be welded on one side. You can weld not a nut, but a welded tube with rods, this is at the request of the master. You can leave the resulting design as it turned out and test it on a non-working shock absorber.

You will use it more than once, and maybe not twice, so do not think that this is a one-time device. In order to quickly and cost-effectively complete this auxiliary part, analyze what spare parts you have at home. If the welding mechanism is not available, then you can do without it, but using other parts.

Turn on fantasy and logical thinking before you start work. You can outline an action plan on paper and do it step by step. Consult with experienced motorists, craftsmen - maybe they will tell you the most light version production of a do-it-yourself puller. In any case, if you want to save money on such an auxiliary device, you will definitely succeed. Good luck!

Video " Do-it-yourself shock absorber spring remover ”

On the record, an auto mechanic talks about how you can make shock absorber spring extractor. After watching the video, you will be aware of what materials and tools you need to prepare, as well as how the manufacturing process takes place.


The article will tell you how to make a useful device for every car and motto lover with your own hands.
Sometimes it becomes necessary to sort out old shock absorbers, replace the oil seal or other worn parts in them. True, for this they need to be disassembled, and it is not so easy to remove the springs from them and install them back after repair. Of course, there is a large selection of ready-made, factory-made pullers on sale, but they are pretty decent, and the need to use them does not arise so often.

Here are the factory pullers:


The design of the puller presented in the article is extremely simplified, as they say "everything ingenious is simple!".

To create a device you will need:
- Stud and nuts to it;
(the thickness of the stud depends on the thickness of the springs that need to be removed, the author used a 12mm thick stud)
- Two crescents on the hairpin;
- Tube according to the diameter of the stud;
- Bulgarian;
- Welding machine.


First you need to cut off two pieces of the hairpin of the desired length, the more, the more universal the puller will be.
Such platforms are welded to the crescents to increase the area of ​​\u200b\u200bcontact with the spring:


On the other side of the puller, such a bracket is put on. A spring retainer is welded onto a suitable diameter tube. The bracket has no threaded connections, and slides freely on the stud:


To compress the spring, a nut is screwed over the bracket and tightened to the desired compression of the spring.
Here are photos of the finished puller. As you can see, the mechanism works.

Dear site visitors Labuda blog"Today we will consider one of the options for making a do-it-yourself do-it-yourself shock absorber spring puller, and also look at step by step photos assembling the spring puller and video ..

Every car enthusiast who has ever repaired a suspension passenger car he knows perfectly well how difficult it is to remove the shock absorber springs, and in order to perform this operation without a special tool, you will have to pretty contrive. But if you think a little and apply ingenuity, then a simple shock absorber spring puller can be made independently and at the same time with minimal cost so to speak simple and a budget option a tool that makes life easier for the motorist.

Device and principle of operation The presented puller is actually quite simple and understandable, the compressive force of the screw coupler of the spring is taken as the basis, namely, 2 metal hooks are installed on the stud that hook on the spring and, under the influence of tightening the nut, the spring is compressed and then removed from the rack.

And so, let's look at what exactly is needed to assemble the puller.

materials

  1. metal pipe 16-20 mm
  2. hairpin M-14
  3. corner
  4. nut 2 pcs
  5. grease

Instruments

  1. welding inverter
  2. drill
  3. vise
  4. a hammer
  5. wrench
  6. angle grinder (Bulgarian)

Step-by-step instructions for creating a do-it-yourself shock absorber spring puller.

For the manufacture of metal hooks, we need water pipe 16-20 mm. We first saw along making a cut, and then the required number of blanks is sawn.

Here's what happens.

Then the workpiece is clamped in a vice and one side of the hook is straightened with hammer blows.

These are the hooks you should get.

Several blanks are sawn off.

Drill a hole exactly in the center.

Hooks are welded to the corners.

In addition, to strengthen the structure, it was decided to weld a piece of the tube.

After that, we assemble the puller into a single structure and proceed to dismantle the shock absorber spring, the hooks cling to the spring, and then we begin to tighten the nut along the thread of the stud, thereby upsetting the spring and extracting it. To consolidate the material covered, you can watch the video. Happy viewing.

In order to tie the shock absorber springs with your own hands, you need to purchase a puller and follow the simplest instructions. Then this process will become easy and affordable for everyone in the garage.

Quite often it happens that the shock absorbers on the car wear out or fail. This is not surprising, and there can be many reasons for such consequences. In this case, each owner of the car is faced with a number of troubles and the only solution may be to replace the shock absorbers.

It can be done in service center or in your garage, however, this will require a spring coupler (some call them shock absorber coils), which require a special puller, as well as some knowledge and skills.

How a shock absorber works

A mandatory component of each shock absorber is a spring. There are now all sorts of progressive types of this mechanism, such as oil or pneumatic, however, the design of each of them includes the same spiral element that helps to maintain a given level of the car above the ground, and also facilitates work when the shock-absorbing device itself is loaded.

Quite often it happens that the shock absorber is in perfect order, while the spring element has worn out, lost the necessary rigidity, or even burst. In this case, it needs an urgent replacement, which can only be done by hand with a puller.

There is a reverse side of the coin, when everything is in perfect order with the spring, but you need to repair work with the shock absorber itself, in this case the puller will be indispensable.

What is a puller

A puller is a special device that allows you to compress the shock absorber springs so that you can continue repair work in the future. There are a lot of variations of this device, but the most common spring puller is two metal rails with threads cut along their entire length and hooks fixed on both sides, which, when turned, go towards each other. Those. when it is necessary to compress the springs, it is enough just to turn the rail, and the fixed hooks will tighten the spring.

There is an even more simplified puller method - belt. In this case, two "frogs" are used with strong fabric belts tucked into them. The belts are thrown onto the upper and lower coils of the springs, then the owner of the car begins to work with “frogs”, pressing each one in turn. Subsequently, these actions tighten the belts, and the “spiral” begins to tighten, after which repair work can be carried out.

Spring tightening process

Let's start with the fact that the pullers described above are not the only ones of their kind, there are several more configurations of this device, you can also make it yourself or just buy it. However, without it, the screed will be a nightmare and an almost impossible task.

When starting to perform this operation, it is necessary, first of all, to remove the shock absorber strut, after putting the car on a jack and fixing it securely.

Next, the puller is attached to the upper and lower coils of the springs, and work begins by hand. Depending on the principle of operation of your puller, you will either rotate some of its elements, or, as in the case of the “frog”, alternately work with two pedals.

At this point, the screed can be considered complete, the main thing to remember is that you should not compress the spring completely, increasing the risk of breakage of both the spring itself and the compression device. It is enough just to release the element you need from pressure and repair or replace the shock-absorbing mechanism.

As for the use of a puller, it is designed to facilitate the entire repair process, because without it you would not only have to fix the rack with a vise, but also make great efforts to compress the springs, you would need someone to hold them while you are doing the whole mechanism etc.

In addition, using this device, you make the repair process safe for yourself, practically eliminating the chance of a spring failure.

Conclusion

The process of tightening the shock absorber springs is the measure that every driver who wants to repair the shock absorbers with his own hands, and not take his “iron horse” to a car service, faces. However, without a puller, this operation is not completely impossible to carry out, but it will be accompanied by a lot of difficulties and a rather high risk for a person. If you use such a simple and inexpensive screed device, the risk is immediately minimized, and the work process itself becomes easy and fast.
