Despite the fact that stores sell towbars for any car, making a towbar with your own hands is much easier, faster and cheaper than waiting for delivery and then visiting a car repair shop to install it.
Making a towbar itself is not difficult, the main thing is to know how to use a grinder and welding.
Look at the assembly drawing of a homemade towbar for Renault Logan, you will agree - it’s not difficult to make it yourself!
Drawings will be required for manufacturing.
Drawings of a towbar for Renault Logan
So, look at the pictures below - these are the very drawings according to which you can make a towbar for a Renault Logan with your own hands.
The first drawing is a power beam, something that transfers forces from the hook to the supporting body of the car.
The side bracket is a connecting part of the power beam and the body of the Renault Logan car.
Hook. The trailer will cling to it. The hook is made of a pipe with a ball welded to it; to bend it, you need to use a pipe bender.
Flange. One of the parts of the power beam.
Cheek. Helps in attaching the hook to the load beam.
As you can see, there are no scarce parts or difficult places; anyone who knows how to use welding can make such a homemade towbar.
Of course, if you have no desire to do handicrafts, then you can take a ready-made tow bar.
After you have purchased or made your own towbar, you need to install it on the car.
I won’t describe the installation; it’s better to watch how to install a tow bar on a Renault Logan in the video.
As you can see, there are no problems here either, everything is done quite simply and does not require a special tool.
Anton comments:
Well, if you really want it, then of course you can install a tow bar on Logan. The only question is that these towbars on non-frame cars break the body.
Semyon comments:
Well, why does it immediately break? It drives quite well with a trailer, the main thing is not to drive over bumps!
Ivan Popov comments:
Come on, I used the towbar to pull out a stuck car - everything was fine!
Anton comments:
Still, it is better to install the towbar on a frame car. Otherwise, a sharp jerk can tear the car body in half. Look on YouTube for videos of how cars tear when pulled out.
Alex comments:
Thank you
Ruslan comments:
The dimensions are not visible on the drawings. I want to turn a sphere onto a hook.

Please tell me. Where can I get a drawing according to which I can make a towbar? Thank you
The tow bar for Renault Logan can perform several tasks. Many motorists attach additional towbars and other movable structures to the car for transporting goods.
Do-it-yourself square towbar
The American towbar differs from the European one in that it is made for a square, and not for a ball clutch. Instead of a ball hitch hook, there is a square measuring 50x50 mm - below we will look at how you can make it yourself:
- Cut the edges from a 200 mm channel to get a plate of the required length - drill holes in it for fastening to the frame;
- For additional vertical fastening, weld a corner 50x50x4;
- Bore the holes in the frame that already exist - drill through them in the upper part;
The strength of the structure allows you to carry a full trailer
- Insert pieces of half-inch pipe inside the frame so that it does not flatten when tightening the mounting bolt;
- For a horizontal section, weld half-meter plates 8 mm thick and 10 cm wide;
- Make a pipe from two corners 75x75x6 and weld to the fasteners;
- take a 60x60x4 profile pipe 20 cm long and weld a strip of steel 4 mm thick and 30 mm long onto the working end;
- cut out a square section in the power frame and place it there. Weld and reinforce with slopes;
- Next you will need to drill holes for the locking pin;
- Now you can move on to sanding, puttying and priming, after which painting is done - the paint has dried, the product is ready.
Preparatory procedures
We are considering installing a tow bar with our own hands on a Renault Logan car. First, the car enthusiast needs to decide on the choice of towing device. If you have welding skills, you can make the part yourself, having a welding machine and steel.
There are many videos and photos on this topic on the Internet. These videos for Renault Logan describe in detail the process of welding a towbar from several components. The positive aspects of making a towbar with your own hands include:
- saving money, since this procedure will require a welding machine, steel fasteners and a pipe bender, the financial costs will be minimal;
- the quality of workmanship and the strength of materials are on the conscience of the owner of Renault Logan. With the proper level of skill and the presence of good steel, this is undoubtedly a plus, but otherwise it can result in dire consequences in the form of a traffic accident.
Is it necessary to register a towbar with the traffic police in 2020?
In this case, everything depends on the tow bar itself and the documents available for it:
- If there are documents for the towbar, then the driver does not need to contact the traffic police to make changes to the registration certificate. You can simply install the towbar and safely operate the car with a trailer.
- If there are no documents or they cannot be restored, then installing a tow bar is a design change that should be registered with the traffic police.
Note. The necessary documents for the towbar will be discussed below.
For example, if the original towbar is installed on the car at the factory, then no additional actions need to be taken when contacting the traffic police to register the car. If the traffic police has any questions about the vehicle in the future, you can at any time request documents from the automaker and defend your own case.
On the other hand, if the towbar is made independently and simply welded to the car body, then this is a design change. To register it, you need to contact the traffic police. Moreover, it is far from certain that permission for the installation will ultimately be obtained.
Let me remind you that the algorithm for making changes to the design of a vehicle is discussed in a separate article:
Making changes to the design
It implies that the car owner must contact various organizations 7 times, i.e. quite labor intensive.
In this regard, in practice this option is also possible. If the towbar is already installed on the car, but there are no documents for it and it is impossible to restore them, then it may be easier, faster and cheaper to buy a new towbar with documents than to try to register a change in the design of the car with the traffic police.
Disadvantages of self-installation
The negative points when making a towbar with your own hands include the following:
- installing homemade fasteners with low quality workmanship may require additional time;
- the total time for manufacturing and subsequent installation may increase in proportion to the degree of poor quality of manufacturing, and in general, even with good welding quality, it will take a lot of time;
- The owner will have to think through the wiring diagram along with the drawings independently, which in the absence of proper experience is fraught with difficulties (shorting of contacts in the presence of poor wiring, short circuit when making an incorrect circuit, other negative consequences).
Step-by-step description of the work
✓ First you need to remove the bumper. ✓ Next – cut off the eyes. ✓ Here you need to take a drill and make holes.
✓ We take a welding machine and weld the fasteners. ✓ Now you need to weld the second tube in the center to make a right angle connection. ✓ You need to take a grinding wheel and coarse sandpaper and clean the seam and edges of the tubes. ✓ The manufactured structure is coated with a primer. ✓ Now the structure is covered with paint.
To strengthen the spar, we install a small angle with nuts. This will create a tow bar with a removable structure. You can use headlights to power the towbar, and use a connector to power the socket. Ready! Now you have a full-fledged homemade tow bar.
When making a homemade towbar, you need to try it on all the time, controlling where it is placed on the car.
What you need for work
If you don’t have a welding machine or desire, the part can be purchased. How much does a new towbar cost? Its price varies depending on the area, but does not exceed the limits of 4 to 15 thousand rubles. The cost depends on the type of new tow bar.
Removable devices for transporting cargo weighing up to 1 ton will cost around 5-8 thousand rubles. Electrical products, differing in their manufacturability and increased load weight, will accordingly cost more (in the range from 10 to 15 thousand rubles).
The most popular manufacturer of parts for this model is. The products are deservedly in demand due to their good price-quality ratio.
Fortunately, specialized stores offer a wide selection of models for the Renault Logan car. Using the factory article number (for example: 9010), the owner of a Renault Logan will be able to choose a part that is suitable in its characteristics for this car (before purchasing, you still need to check the dimensions and places of fastening of the part to the body, which is why it is necessary to take measurements of the original fasteners before going to the store ). The advantages of a purchased part are obvious:
- the connection diagram was developed by the manufacturer taking into account the characteristics of the Renault Logan car for any type of towbar;
- at the manufacturer’s factory, the part undergoes repeated tests for strength and reliability, for which specialized services have a certificate of conformity;
- the owner does not need to personally develop wiring drawings for installing the tow bar.
Which tow bar should you choose?
Towbar from the trendsetter Thule
A towbar is considered a model product, which means that each model has its own product. Therefore, before you come to the store, you must know exactly what type of towbar is needed for your car.
There are many different types of towbars on the market and they are all divided into groups:
It clearly shows what each type of towbar looks like.
- Option A – designed for transporting cargo with a maximum weight of 1500 kg. (It is the simplest in design).
- Option B - has the same load capacity, but the design includes a semi-automatic device on a nut.
- Option C - the design is a semi-automatic eccentric, the load capacity is increased to 1800 kg.
- Options G and F – differ in the number of mounting holes to the body, have a forged iron structure and have a load capacity of 2000 kilograms of cargo.
For the Renault Logan car, the simplest type of design is used: option A, so before choosing a tow bar, pay special attention to this. >. >

Connection process
It takes place in several stages:
- first you need to drive the car into the inspection hole;
- then additional supports must be placed under the front wheels (this is necessary to give the car the necessary stability);
- then proceed to the installation of the transverse beam, as the basis of the entire structure: the beam is attached to the body through special holes using bolts;
- Next, you need to install fastening plates and washers with nuts on the beam for subsequent fastening;
- then the clutch ball is adjusted, its position should correspond to the longitudinal axis of the car;
- then the towing hook must be installed on the pre-installed brackets;
- after completing the mechanical part of the installation of the structure, it is necessary, guided by the diagram, to connect the element to the car;
- To do this, you need to disconnect the car battery;
- It is necessary to route electrical wires through a special hole in the trunk and connect the towbar to the standard on-board network.
How to mount the device?
How to install correctly, step by step? To independently install the element on a Renault Logan, we install the car on an overpass. A pit is also perfect, and in its absence, we hang the rear axle using jacking devices. In the latter option, we resort to the mandatory use of recoil stops.
Tool
For work we use:
- screwdriver with slotted profile;
- keys with standard sizes: “8”; "17" and "19".
Before starting installation operations, it would be advisable to empty the luggage compartment of unnecessary items, which will significantly increase the convenience of the “operation”.
- Remove the muffler pipe from the rubber suspensions. For these purposes, we press the muffler body downwards, then we find a hole that appears in the stretched suspension. We insert a screwdriver, pre-lubricated with grease, into it and remove the muffler, subsequently placing it on the rear axle beam of the Renault Logan.
Important! After dismantling the muffler, we carefully clean its mounting bracket and suspension from traces of grease, since these elements must be dry during reassembly!
- Next, we go inside the trunk of Renault Logan. On the inner surface of the “cheeks” we find plastic plugs that plug the technological holes on the surface of the side members. Using a screwdriver, we can easily dismantle these elements.
- We repeat a similar operation under a Renault Logan car. From the bottom, the holes are carefully masked using factory self-adhesive tape. After breaking through it with a screwdriver, it would be useful to treat the contours of the holes with anti-corrosion treatment using a special agent (for example, mastic).
- Now we hang the previously indicated power plates on the bolts, onto which we attach the power beam.
- We carry out full tightening of all bolts only after 100% assembly, this is exactly how the installation of the tow bar should be. If the structure is not self-made, but purchased, then its installation is carried out in accordance with the algorithm indicated in the attached instructions.
- The electrical circuit is not complicated, so its installation does not cause any difficulties. For error-free wiring, it will be enough to disassemble the left stern headlight in order to study the switching features. From this headlight you can lead cables for connecting lamps: dimensions, brakes and left turn.
- We connect the right turn indicator by connecting it to the right headlight of the car.
Now you know how to install a tow bar. If a towbar manufactured in an industrial enterprise is mounted on a Renault Logan, it is recommended not to attach a socket to it for switching towed electrical equipment. After all, the need for it arises only during towing.
Currently reading: Do-it-yourself repair of RENAULT LOGAN - RENAULT LOGAN. Blog
In all other cases, it is at risk of mechanical damage. A more optimal and safer measure would be to connect the socket to the on-board network using an extended piece of cable located in the luggage compartment. It is recommended to fix it in its original place if necessary.
A towbar is an additional towing equipment designed to hitch a vehicle with a different body and a trailer. It consists of a supporting frame, which is attached to the car body, and a connecting hook with a ball (diameter - 50 mm). The design of the tow bar is regulated by Gosstandart 28248-89. The choice of towbar depends on the make and modification of the car.
Renault Logan is a French budget car of class “B”. The main production is located at a plant in Romania, but since 2005 the model has also been produced in Russia (at the Aftoframos and AvtoVAZ enterprises). It was conceived as a compact family car for developing countries: ground clearance was provided, and the bottom design was thought out. In 2004, the company introduced a sedan model.
In 2007 and 2022, the model underwent modifications. The interior space has become more ergonomic, the quality of assembly, anti-corrosion coating and interior trim has increased. In different countries, the five-seater car is sold under different brands: Renault, Nissan or Dacia.
Drawing conclusions
As a result, the process of installing a tow bar on a given car does not present any particular difficulties for any installation option (both homemade and purchased devices). The main thing is to follow the sequence of actions in the process and precautions.
A towbar is a beam with side flanges that is attached to the side members. There is a hook installed in the center of the beam, to which the trailer is hooked. The towbar design must contain a minimum number of parts. We present a drawing of a tow bar for the first generation Renault Logan. It, that is, this drawing, contains 8 elements. And then we consider what needs to be done to make the tow bar compatible with the design of cars from generation II - those that have been produced by the VAZ plant since 2014.
We show you how to install a towbar easier in the video.
Make it yourself or buy ready-made?
Such a device can be purchased at a specialized store or made independently. Despite the fact that the latter option will save a lot of material resources, many prefer to buy a ready-made option from well-known manufacturers. This is based on certain advantages:
- Even during the design process of the device, a special computer model is formed, through which the likely load on the main fasteners can be determined.
- A towbar, which is produced at the factory, undergoes a large number of various technical inspections before the implementation stage, and throughout the entire manufacturing process. Checks are also carried out in a separate management department.
- The manufacturer, as a rule, bears full responsibility for his products and gives a guarantee, which is usually documented. If an unexpected situation arises, the client can contact the company that manufactured and installed the device and receive some assistance.
It is recommended not only to purchase a clutch from a reputable manufacturer, but also to order its installation from the company’s employees. If you install the tow bar yourself, and then it fails for some reason, you won’t have to count on warranty repairs.
Drawings of all parts with dimensions, option 1 (Renault Logan phase 1 and 2)
You can make a towbar for Renault Logan with your own hands, but you need to study the drawings very carefully. If we are talking about a car from phase 1 or 2, read the text further. The drawings are not suitable for “phase 3”, that is, for the latest generation of sedans.
Complete structure
The entire structure consists of three units - two flanges and one beam. We will call the side flanges brackets. Their drawing is shown in the photo.
Side bracket (2 pcs.)
The assembled beam includes five parts. The beam itself is a pipe with external dimensions of 60 by 40. You can use a pipe with a cross-section of 40 by 40, but then the cutout in the “cheek” will be reduced: dimensions 50 and 115 will become equal to 40 and 125. Everything is simple here.
All parts of the beam assembly
Please note that the M12 nut must be welded to the flange. If this is not possible, mounting holes are drilled in the pipe wall. But it’s better not to do this - the beam must remain sealed!
The drawings of the Renault Logan tow bar shown above were obtained by measuring the parts included in the factory kit. M12 nuts and screws tighten the entire structure, and it itself is attached to the side members with M10 bolts and nuts. By the way, bushings will also be needed. Their dimensions are given in Chapter 4.
Hook
The kit in question included a part called a “hook.” Here are its dimensions.
The most important part of the tow bar
The ball diameter shown here is the standard 50mm. We do not consider manufacturing technology.
Appearance of the towbar according to drawing No. 1
Below is what the towbar from Project 1 looks like. Read on to learn how to install it.
Homemade car from the first generation
For those who don’t know how to weld, it’s easier to forget about making something like this.
The thickness of the steel sheet must be at least 3 mm. The thickness of the beam walls is 2.5 mm. Less is impossible!

Engine malfunctions and repairs Renault Logan/Sandero 1.6 K7M
Engine Renault Logan K7M 710 1.6 l. 86 hp nothing more than a regular K7J 1.4 liter, only with an increased piston stroke (from 70 to 80.5 mm), of course the height of the block has increased slightly, the clutch has a larger diameter, the flywheel has been enlarged and the shape of the gearbox housing has changed.
Structurally, Logan's 1.6 liter engine, like its low-volume brother, has the same archaic design from the middle of the last century with rocker arms and a strange oil pump drive system from lower-end Renault engines of the 60s. Despite everything, with careful attitude to the engine, service and maintenance, changing the oil 2 times more often than according to the instructions, it is very, very reliable; according to internal factory data, the service life of the Logan engine is 1.
6 about 400 thousand km, in practice the engine traveled a little more. In 2021, the K7M 710 was replaced by the K7M 800, the engine was strangled, brought up to the Euro-4 environmental standard, the power decreased to 83 hp, there were no design changes. Disadvantages K7M are the same as the K7J 1 engine.
4, high fuel consumption, often at idle the speed starts to float, constantly (once every 20-30 thousand km) you need to adjust the valves, there were no hydraulic compensators and there are no hydraulic compensators, the timing belt drive, if the belt breaks on the Logan 1.6, the valve bends, Therefore, we change the belt every 60 thousand km.
Still the same crankshaft oil seal leaks. The motor is noisy and there are vibrations. On the design of the Renault Logan 1.6 engine and where the engine number is located, information is presented in the article “K7J engine”, which, apart from the volume and accompanying changes, has no other changes.
All malfunctions and the reasons for their occurrence are also described there. Speaking about which engine for Renault Logan is better, 1.4 or 1.6 8 valve, take 1.6... the engine is the same, but the small volume is very weak. Also on the basis of the K7M, the K4M engine was created with a 16 valve cylinder head and other significant innovations, power such a motor is significantly higher and if you choose (for example, Logan, Sandero), always take it, you won’t regret it.

Chip tuning of Renault Logan engine
For the Logan K7M 800 engine, you can remove the catalyst, return it to its original power of 86 hp, install an exhaust and flash the sport firmware, maybe add a couple more horses, but nothing will change significantly, except fuel consumption, now your engine will eat more))
Compressor and turbine for Logan 1.6
The installation of turbocharging and compressor is described HERE using the example of a 1.4 liter engine and all this is applicable 1 in 1 for a 1.6 liter. The power of the Logan 1.6 engine will be on average 5-10 hp. more with a similar approach. Looking ahead... you won't be able to achieve high power.
ENGINE RATING: 3
The reason for the cap. repairs resulted in increased fuel consumption - 10-11 liters. on the highway and up to 14 hp. around the city, increased oil consumption, strong oil deposits on the spark plug of the 1st cylinder. Compression measurement: 10-8-8-9 (not enough!).
Technique for installing a tow bar to the body
You need to make four bushings, such as in the drawing. The towbar from any project is assembled using M12 bolts and nuts. Well, they secure it with M10
x90 screws.
By the way, it is advisable to use lock nuts and washers.
Additional fasteners
It is important to follow one rule: all nuts are first tightened. When the towbar is assembled, you need to forcefully pull the beam back. And at this time, without releasing the beam, tighten the M10 nuts one by one.
It seems that it will still be impossible to do without an assistant.

Renault Logan 1.4i Road Cruiser › Logbook › Bosal 1418-A towbar, installation
I decided to expand the functionality of my car with a trailer, because... The harvest from the dacha is scheduled to be removed soon.
Based on the characteristics and reviews, I chose the towbar from the trusted manufacturer Bosal, towbar model 1418-A for Logan phase 1 and 2 (with electrics included).
The process of installing a towbar on Logan is wonderfully described by Wulf-moto in the recording www.drive2.ru/l/1986693/ I will only note the main points.
1. It’s much more convenient to work together. I worked alone and had a lot of trouble. Especially when tightening the fasteners to the body side members. Doing this alone is EXTREMELY inconvenient (and generally only possible if you have long and tenacious arms).
2. It is highly advisable to secure the spacer bushings to the bolt entering the spar, for example, by placing pieces of wire insulation under them. Otherwise, one awkward movement, and the bushings will remain in the side members (most likely forever).
3. The cross beam is quite heavy in weight, especially when working alone - during installation I was helped by a stool, on which I placed the opposite end of the beam while I was screwing it on. DO NOT TIGHTEN the bolts until you have assembled the 2 mounts to the side members and the cross member. Once assembled, tighten alternately on each side.
4. On specialized forums, it is recommended to fill the towbar socket with lithol on the inside to prevent oxidation of the contacts and increase service life. I followed this advice. Moreover, I coated the contacts on the outside as well. If the measure does not justify itself, I will move the socket to the trunk and will only take it outside when transporting a trailer.
5. Complete wiring is connected to both lights. From the left is taken: turn signal, brake signals, fog lamp and ground. On the right is the turn signal, dimensions and license plate illumination. I ran the wires along the top of the cross beam, securing them with zip ties. On the left - I led it into the trunk through a rubber plug for the license plate light wire, on the right - by making a hole in the plug in the “pocket” of the trunk.
6. It seemed to me more convenient and faster to connect to the wiring of the lamps using a traditional good twist. With a sharp knife, I stripped 0.5 cm of insulation from the wires without cutting them. According to reviews, the clamping terminals-couplers included in the kit often break wire strands. They were sent to reserve.
7. It’s impossible to work alone without a ratchet. And in general, get a ratchet and make many men’s hobbies 100,500 times easier for yourself
