Car oil filter remover. Oil filter chain puller: how to use, what it is intended for, the necessary materials and equipment for making a do-it-yourself puller. We make a do-it-yourself puller

This replaceable element has to be changed on the car engine every 7-15 thousand kilometers along with the next replacement of engine oil. Usually it is attached to the engine at its bottom, and it is not so easy to get close to it, but it is even more difficult to turn it out, since it is not possible to grab it with two hands.

In addition, during the time from replacement to replacement, the filter housing is covered with dust, dirt, various oily deposits, and hands, not finding the right grip, slide over the surface of the part.
What to do if it was not possible to turn out this interchangeable product with one hand?

You should use the following simple, but quite convenient and effective devices.

1. Puller in the form of a metal band and a bolt with a nut

The device consists of a metal tape, which with its ends passes through the slots in the curly bracket, symmetrically located relative to its center, against which a bolt with a nut screwed onto it rests.
The tape forms a loop-girth, and its ends are fixed on two opposite faces of the movable nut by means of short screws. If the bolt is unscrewed, the nut slides down and the diameter of the loop increases. When the bolt is screwed in, the nut goes up and the loop is shortened. The bracket in its lower part is made along the arc of a circle.

The puller loop is freely thrown over the oil filter housing and, by screwing in the bolt, is tightened due to the fact that the nut rises along the bolt and pulls the ends of the metal loop along with it.
When the loop tightly clasps the filter housing, the puller becomes a kind of lever rigidly fixed to the removed unit. Now it remains only to apply a small amount of force to the puller-lever counterclockwise to rip the filter from its seat.
After that, the puller can be removed, and the filter can be unscrewed with the force of the fingers of just one hand.

2. Puller type "Crab"

It is a kind of planetary mechanism: one central spur gear and three satellite gears of the same size and type, each of which engages with the first.
The outer gears are arranged around the central one evenly along the circumference, that is, at 120 degrees to one another. All of them are fixed with their axes on a strong and rigid round disk and a triangular plate with rounded corners on the reverse side of the gears.
The central gear is driven by a key through a nut located with the front side of the plate on the continuation of the axis of the central gear. At the same time, the side gears-satellites begin to rotate within less than one revolution around their axis, which is quite enough for this type of clamp to work.

The clamping of the oil disc body is carried out by L-shaped brackets of circular cross section, which are welded with the short side perpendicular to the generatrix of the side gears right in the center so that the angle between them is also strictly 120 degrees. Moreover, the long rods of the brackets should be parallel to each other and oriented in the direction opposite to the location of the nut. For a better grip, the long sides of the staples, starting at least from the middle to the end, are provided with a protruding longitudinal notch.
If the brackets are arranged radially, then the conditional cylinder inside them has a maximum diameter. Turning the nut to the left or right brings the brackets together, and the diameter of the conditional cylinder decreases.

Using this device is quite simple: we grab the oil filter housing with brackets and turn the nut to the left with a wrench, thereby twisting the filter from its seat. When the nut is rotated to the right, the filter will, on the contrary, be twisted.

3. Chain puller

The main element in it is a piece of a chain, which at one end is fixed in the "spear" of the handle along with a swinging bracket, its other end is free. But, so that the chain does not jump out of the “horn”, a hairpin is threaded into the end link, the ends of which are separated.
To unscrew the oil filter, the chain is thrown over its body, pulled up by the free end and thrown onto the two teeth on the handle. They do not allow the chain girth tightened around the filter housing to disperse and loosen the clamp.
Now it remains only to turn the handle of the puller counterclockwise by hand, and the filter can be easily unscrewed. If you throw the chain in the opposite direction, then by turning the knob clockwise, the filter can be installed in its original place and tightened to the stop.
After completing the unscrewing or tightening, it is enough to remove the force from the handle, as the chain will loosen by itself and it can be removed from the filter housing.

4. adjustable wrench

Perhaps this is the most convenient fixture, if its dimensions allow spreading the jaws to the girth of the oil filter housing, the diameter of which can sometimes exceed 100 mm. And also it needs a place commensurate with the length of the adjustable wrench. And how to find it on the engine of not only a passenger car, but also a truck? Therefore, this method is almost useless in practical terms.

5. Powerful screwdriver

Modern oil filters installed on car engines are mostly disposable. Therefore, after the first use, they are good for nothing. So, there is nothing to pity them.
Hence - the last "barbaric" way to unscrew the oil filter using a strong and, preferably, a long screwdriver with a sharp sting and a strong handle.
We direct the tip of the screwdriver to the generatrix of the filter, as close as possible to the bottom of the removable part. Holding the screwdriver perpendicular to the surface of the case, we strike the end of the handle with a hammer until we break through the upper and opposite walls. The tip of the screwdriver should come out.
Thus, we have created an impromptu lever, to which it is enough to apply a small force counterclockwise, and the filter will be easily unscrewed. Moreover, the longer the screwdriver, the less force is required to unscrew. The disadvantage is the same as in the previous case: a lot of space is required.

Note in conclusion

How to unscrew the oil filter if the first three devices were not at hand, and there is no place to use the last two. You should try using sandpaper.
To do this, put on gloves on your hands, cut off a proportionate piece of coarse sandpaper, clasp the filter housing with it and try to move the filter with both hands. Usually this is possible, because it is only necessary to overcome the crushing force of the annular rubber gasket to seal the filter and the tightening on the thread.

After graduation warranty period, most drivers are switching to self-service cars. Changing the oil is not particularly difficult, with the exception of removing the oil filter. At service stations, a special puller is used, which can be purchased at car dealerships.

The device can be universal, or designed for certain models of filter cartridges. But since you decide to save on maintenance Why buy extra tools? You can make an oil filter puller with your own hands. Especially since you only have to use it once a year.

Why do you need a puller at all?

If there is normal access, you can unscrew the oil filter by hand.

But such a convenient location is not in every car. In addition, the filter cartridge is usually coated with oil and dust, and slips in the hand.

The seat (threaded flange) is subject to thermal stress during engine operation. The layer of oil is coked, and turns into adhesive-sealant. When unscrewing the filter, your hand may slip and you may be injured.

In addition, the work is carried out in a narrow space, visual control is not always possible. To securely grip the filter housing, a special tool has been invented that allows you to apply sufficient force.

Rigid puller (cup)

It is made in the form of a large-diameter end head, with a seat for a handle with a square. The cup remover follows the shape of the oil filter so does not damage the body, but only fits certain models, compatibility depends on the size of the filter body.

Crab puller

It is a faceplate with a gear mechanism. The L-arms rotate synchronously towards the center, providing a tight grip on the oil filter housing. The device is universal, but during operation it damages the paintwork of the cartridge.

Crimp stripper

Covers the cylinder with a steel band. The tightening mechanism is lever or screw. With the help of such a puller, you can unscrew any filter, but the device has a serious drawback: the frictional properties of the tape are not enough to move a strongly clamped filter cartridge from a stuck thread.

Crimp puller rigid

Ring-type tool, oil filter coverage is made by segmental toothed clamps. It has limited working diameter.

Oil filter chain puller

It works on the principle of a tape, but a chain is used as a fixing element. The tool is universal: by adjusting the length of the chain, you can remove the filter of any diameter.

Most drivers are completely sure that an oil filter puller is an absolutely useless and unnecessary tool that only car mechanics should have. The other part has probably already encountered a problem when it is impossible to unscrew the filter with the help of hands. The choice of this puller is limited only by the car model, because not all filters are made to a single standard, so it should be selected in accordance with the car model.

The main types of oil filter pullers

Almost all pullers have the same structural similarity - a matte handle, usually made of plastic and a chrome base. Among the differences, it can be noted that pullers can be universal or those that are able to unscrew only a specific filter size, most often round.

The bulk of the pullers allows you to dismantle the filter elements from the engines internal combustion or housings of filter elements, with a replaceable insert. Based on the above features, the following main types and types of pullers can be distinguished:

• belt
• Tape
• With special adjustable grips
• Chain
• Pincer or crescent

If you make a comparison, then the conclusion suggests itself that a puller with an adjustable grip will be the best and most rational. Actually, it is not. The fact is that such a puller is designed for a certain range of sizes, to which the filter of another car simply does not fit, secondly, due to a large number adjusting devices for him, because of which it is not always possible to get close. After all, the engine compartment is very narrow and does not always allow you to install long tools on the elements.

How to use a cup puller?

The cup-shaped oil filter has become more widespread. They bear this name because of their shape, which resembles the most ordinary cup.

You need to choose such a puller very carefully. The fact is that it is made to a specific filter size and, having a difference of at least a couple of millimeters, can easily become the most useless tool in the garage. The most competent decision would be to purchase a set of such pullers, then you definitely can’t go wrong. "Cups" in such sets are located in a special case in the form of a small suitcase, which improves the convenience of storage and transportation.

Many "cup" pullers have special square holes turnkey, or bulge under ring spanner. This design feature allows you to cope with dismantling with virtually no problems, applying the least effort to the tool. If this is not provided for by the design, then the drivers modify such details on their own. Many sets may come with an additional cup tool.

To remove the filter, you need to put on the cup with the side on which the edges are located on it. They must exactly match the edges located on the filter housing, otherwise, you risk getting slippage that will not help you unscrew the filter. Such a tool has been considered the most convenient for quite a long time. Thanks to its edges, it eliminates any slippage, and its compact size allows you to work inside any engine compartment. However, to achieve this result, you need to select a tool with high accuracy in size.

Crab puller

Such a puller has the necessary range of settings for various sizes of oil filters. It consists of two metal plates, round in shape, between which there are 3 clamps with paws. The working part of the tabs has a rough pattern to eliminate the possibility of slipping and ensure maximum engagement with the filter housing. Fixing and clamping of the legs is carried out with special adjusting bolts.

First, the legs of the puller are adjusted to the diameter of the filter, and the crab is put on it. We remind you that in order to achieve the best engagement, pull the clamps as tight as possible. After that, install a special key in the square groove of the device and unscrew the crab along with the filter.

The process of turning the filter inside out is completely identical to unscrewing the filter using a “cup” puller.

The main disadvantage of the crab is the narrow range of regulation. This means that it has limitations on large and small oil filters. Therefore, the purchase of such a puller should in the future correspond to the dimensions of the filters used.

Nevertheless, there is also a certain advantage of the puller - this is the same ability to work in narrow spaces, which are severely limited by the elements of the engine compartment.

Other types of filter pullers

The chain puller type is a single-row or double-row chain, which is passed into a special groove and has a lock in it. It is stretched according to the diameter of the filter circle, tightened and fixed. Thus, the handle is formed from the rest of the chain and the retainer, acting on which, you can unscrew the oil filter.

The belt puller has a similar design to the chain puller. The difference lies only in the material of manufacture of the gripper. For such a puller, a special belt is used, which is tightened and fixed on the filter housing, also forming a special handle. Thanks to this handle, you can easily unscrew the oil filter.

Probably the most unsuccessful puller can be considered a tape puller. It includes a special metal tape, which ensures the capture of the filter. This design has one serious drawback - too small a range of capture control. The difference between the maximum and minimum diameter is only 30 millimeters. The second drawback is the weak fixation of the capture. Many pullers of this design simply cannot unscrew an oil filter that is too tight.

How to make a belt puller with your own hands?

The basis for the future puller will be a hexagon. Choose the size according to your preference (think about what kind of wrench you plan to unscrew) and cut to the required length. Be careful, too long base will not be effective at all and will seriously limit the space in the engine compartment.

Take a car seat belt and, according to its width, make the necessary cut at the end of the hexagon. Insert the belt there, align and fix with bolts and nuts. Holes in the belt should be burned, but in no case should they be drilled, otherwise, over time, it will begin to fluff and come out of its place.

The end of the belt must protrude from the hexagon by at least 10 millimeters and must be fired to exclude the possibility of its dissolution. The other end of the belt should have the same parameters.

After adjusting the puller to the size of your commonly used oil filter, tighten the loop on the end of the hex and you can safely use the new tool.

How to make an oil filter chain puller + Video

For the manufacture and further use of the chain puller, you will need steel pipe inch size, bicycle chain and a metal plug that can be easily screwed onto the pipe threads.

A hole with a diameter of 9 millimeters is drilled in the plug, and using any triangular file, process its surface until the hole is suitable for the square section of any ratchet. The metal plug is screwed all the way onto the threaded end of the pipe and tightened tightly. To prevent further movement, it is recommended to permanently fix it using conventional welding.

Make holes in the plug in which the end of the chain will be fixed. Put a chain there and thread any pin that needs to be fixed on both sides with any convenient way. Put the chain on the puller and tighten. Make adjustments for the plug in the clamped and unclenched position. Thus, the puller will have two positions: one allows you to put it on the filter, and the second - to capture and unscrew the filter element.

Having decided to change the oil in their car on their own, many car owners are faced with an unexpected obstacle - the oil filter does not want to be unscrewed by hand.

Everything is complicated by the round shape of the filter element housing, which is impossible to grasp normally. It's good if there is an auto shop nearby that sells special pullers different types(they are chain, screw, end, belt, etc.), but what if there is no opportunity to purchase a key, and you need to remove the filter desperately?

In fact, everything is much simpler than it might seem at first glance: there are several simple ways remove oil filter w/o key. We will talk about them in detail in this article.

Method 1: Using a powerful sharp screwdriver and a hammer

This is the simplest of all possible options.
The principle is the following:

1. A large flat screwdriver is taken, a through hole is punched through it in the filter housing (the metal is thin, so this can be done with almost one blow).
2. Next, you need to grab the screwdriver handle and apply force in a counterclockwise direction. Due to the increase in the power arm, the filter breaks off quite easily, after which it can be unscrewed by hand.

Please note that the oil can remain hot for a long time, so safety precautions should be observed.

Method 2: Using an old alternator or timing belt and a screwdriver

1. The belt is put on the filter with a loop, tightened, a screwdriver (a small metal bar, file, etc.) is inserted into the free loop formed and rotated counterclockwise. Instead of a belt, you can also use a piece of clothesline.

Method 3: With a leather belt from trousers

If the old timing belt was not at hand, a regular leather belt is quite suitable.

1. The principle is as follows - the belt is put on with a loop and tightened with force. In this case, the long end of the belt serves as a lever.

Do not forget that the oil filter is unscrewed counterclockwise.

The most important thing is to keep the filter housing clean, otherwise the belt will slip. For better contact, the filter surface can be slightly sanded.

Method 4: Hammer + chisel.

1. Everything is very simple here: a deep notch is made on the filter housing from the side of the thread, then a chisel is inserted into it and the filter is torn off the thread with a tangential blow of a hammer.
2. Next, the filter element is unscrewed by hand. This method is rarely used, since the free space around the filter is limited and there is practically no room for such maneuvers.

How to make a chain wrench for an oil filter with your own hands

The devices listed above are not applicable to all car brands. For example, on a Suzuki Grand Vitara, the oil filter is in hard to reach place and getting to it with a belt and a screwdriver is very problematic.

In this case, a more ergonomic and efficient chain wrench is needed. You can always buy it at the car market for 200-300 rubles or do it yourself.

Craft universal chain wrench for removing the oil filter can be done in several ways, but many of them involve the use of welding machine, which is not in every garage.

However, you can make a practical puller without welding.

All that is needed for this is:

• a piece of an old bicycle chain;
• small segment metal pipe 10-15 centimeters;
• a large nail (100-120 mm) or a piece of thick wire;
• drill with a drill for metal with a diameter of 5-7 mm.

The oil filter puller key itself is very simple:

1. A hole is drilled in the pipe at a distance of 2-3 centimeters from the edge so that a nail passes through it.
2. The bicycle chain is folded in half and pushed into the tube so that the resulting loop approximately corresponds to the diameter of the filter (it should be put on it).
3. With the help of a nail, the chain is fixed in the pipe to the desired length. The key is ready!

VIDEO INSTRUCTION

It is enough to throw it on the filter and press the pipe like a lever (counterclockwise direction) to easily unscrew any oil filter.

This filter is universal and suitable for all types of oil filters, since the length of the loop is adjustable.
