Owning a vehicle often involves not only operating it, but also periodic maintenance or upgrades. One of the most difficult and bureaucratically confusing issues for car owners is when it is required to do so. power-plateMany drivers are still trapped in old stereotypes, believing that any exchange of the engine is equivalent to making changes in the design that require the most difficult expertise in the laboratories. However, the legislation of the Russian Federation has undergone significant changes, and now the procedure has become much more transparent, although it has retained its strict nuances, ignoring which can lead to serious problems with the law.
Modern approach to registration internal combustion engines If you install a new engine that has the same volume, power and environmental class as the original, and this type of unit is designed for your car model by the manufacturer, the process is simplified to a minimum. You do not need to get prior approval in the testing laboratory, undergo repeated tests for compliance with technical regulations or collect a bunch of documents for certification. no need for a design safety certificate (SBKTS) when directly replaced by a similar unitThis changes the approach to the procedure.
However, you can’t simply change the engine in the garage without a subsequent visit to the registration and examination unit. Vehicle passport The number inconsistency found by the traffic police officer during a routine document check or at a stationary post will cause the vehicle to stop and start checking, so the owner of the car needs to clearly understand the algorithm of actions, the list of necessary documents and the procedure for paying state fees in order to legalize changes as soon as possible.
Legislative framework and definition of design changes
The fundamental document regulating the admission of vehicles to operation is the Technical Regulation of the Customs Union "On the safety of wheeled vehicles", which clearly defines what is considered a change in design and what is mere maintenance. is not considered a change of designThis means that the owner is exempt from the expensive and lengthy preliminary examination procedure.
But if you plan to install a motor with different specifications — for example, more power, different cylinder volume, or even from another model of car — the situation changes dramatically. vehicle modificationThis requires obtaining a preliminary opinion in an accredited laboratory, conducting tests, obtaining a SBTC and only then making changes to the registration data, and ignoring this rule when installing a non-standard engine is regarded as driving with unlawfully made changes, which entails a fine and cancellation of registration.
It is also important to consider the environmental class of the unit being installed: if your car was originally Euro-4 class and you install an engine that is only Euro-2 according to its documentation, this may be grounds for refusing registration. environmental must comply with the requirements in force at the time of release of the car or more stringent.
⚠️ Warning: Installing an engine not specified by the manufacturer for this model (even if it fits the mounts) without registration through the laboratory is illegal, this can lead to the inability to continue operating the car and problems with the sale.
The law requires that the replacement unit is not wanted and not stolen. That is why the registration procedure with the traffic police includes a mandatory check of the engine number on the basis of stolen vehicles. Buying the engine "without documents" always carries risks, and if the criminal origin of the unit is revealed, the owner of the car can become a defendant in a criminal case or, at best, lose ownership of the part.
Documents required for registration of replacement
The collection of documents is the first and most important step in the legalization of engine replacement, and errors at this stage can lead to repeated visits to the traffic police, loss of time and nerves. contract Even if you buy an engine from a private person, you need to make a simple written contract that will include the passport details of the seller and the buyer, as well as the engine number, its model and date of sale, which is the analogue of the PrEP on the car and serves as proof that you did not steal the engine.
If the engine was purchased in a specialized store or at a car dealership, you will be given check The number of the unit must also be clearly stated in these documents, the absence of the number marking on the check may cause the refusal of registration, since the inspector will not be able to identify the goods. In the case of an engine received by you as a spare part on an insured event or as part of a warranty repair from an official dealer, the main document will be the corresponding certificate Or an order-outfit with the seal of the organization.
In addition to the documents on the engine itself, you will need a standard package of documents for registration of the vehicle. It includes a vehicle passport (PTS), a valid registration certificate (STS), a passport of the owner of the car and a valid CTP policy. that the CTP policy must be issued on the current data of the car, but changes to the new engine in insurance usually occur after or at the time of visiting the traffic police, although some insurance companies require prior notice.
☑️ Documents for the traffic police
A special case is when the engine documents are lost or never were (for example, when buying an old car with an already replaced engine). forensicsIf the examination shows the purity of the unit, the traffic police can go forward and register changes based on the expert's opinion, but this is an exceptional practice, and you should not count on it without the presence of primary documents.
Step-by-step instructions: the procedure for actions in the traffic police
The procedure for making changes to the registration data of the car in connection with the replacement of the engine is strictly regulated by the administrative regulations of the Ministry of Internal Affairs. The first step is to make an appointment with a convenient traffic police unit. This can be done through the portal "Public Services", which will allow you to choose a specific time and avoid queues. When recording, you should choose the service "Change registration data in connection with the replacement of the engine" or similar wording available in your region. It is important to understand that you need to arrive at the traffic police station on the car, since the inspector must conduct a check. vehicle inspection.
Upon arrival at the unit, you must pay the state fee. You can form a receipt on the traffic police website or through the bank application. After payment, you fill out the application form. The application under the heading "Amendments" should indicate: "Replacement of the engine with a similar number [new engine number]." The application is accompanied by the entire package of documents collected, including copies of the contract for the sale of the engine and checks. Originals must also be carried for reconciliation.
The next step is to go through the inspection on the observation deck, and the inspector checks the body number, frame number and, most importantly, engine number against the data in the application and the documents provided, checks for no signs of forgery, digestion of the numbers, or damage to them by corrosion, which makes reading impossible. If everything goes well, the inspector puts a note on the application. If you have questions or suspicions, the car can be sent for additional examination, but with clean documents, this is rare.
⚠️ Warning: Before traveling to the traffic police, make sure that the engine number is clean and readable. If it is covered with oil or covered with dirt, the inspector has the right to refuse inspection until the contamination is eliminated.
What to do if the engine number is not read?
If the engine number is corroded or filled with paint so that it cannot be read, the inspector will refuse registration, in which case an expert study will be required to restore the marking or establish whether it has changed, this is a paid and lengthy procedure, so it is better to clean the room in advance with a brush and degreaser, without damaging the metal.
After a successful inspection, you return to the application window and submit a completed application with the mark of an inspector. The traffic police officer will check the documents on the databases for restrictions and tracing. If everything is clean, you will be issued a new Registration Certificate (CTC) with the changes and put a mark on the PTS (if it is paper) or put an entry in the electronic PTS. This procedure is considered complete, and you can safely operate the car.
Cost of registration and the size of state duties
The financial aspect of the issue is also an important aspect that should be considered when planning the budget for replacing the engine: the cost consists of several components: the price of the unit itself, services for its installation (if you do not do it yourself) and state fees. In the context of interaction with government agencies, we are interested in duties. Their size is fixed and set by the Tax Code of the Russian Federation, but it can change, so the current figures should always be checked on the official website of the traffic police or the portal of public services.
The main payment that will have to be made is the issuance of a new Vehicle Registration Certificate (VC), because one of the main components of the car changes, the old document becomes invalid and must be replaced, and if the PCA runs out of free recording space or if you switch to electronic format, a new PTS may be required, which is more expensive. The table below shows the approximate government fees that are relevant for the current period.
| Type of service | The amount of duty (ruble) | Note |
|---|---|---|
| Issuance of ITS (plastic) | 1 500 | It is needed when changing the engine |
| Amendments to the PCA | 350 | If the PTS is paper |
| Issuance of a new PCA | 800 | If the old seats are out of place |
| Issuance of new numbers | 2 000 | Not required for engine replacement |
It is worth noting that when paying the state duty through the portal “Public Services” (if such an opportunity is available at the time of payment), a 30% discount was previously in effect, but in recent years its application has been suspended. However, electronic payment avoids queues at the terminals in the branch. It is important to keep receipts of payment, although in most cases payment is recorded in the system automatically, and a paper check may not even be required, but it is reasonable prudence to have it in case of a technical failure.
Keep all checks and contracts for the engine even after successful registration, which may be needed when selling the car so that the new owner can prove the legality of the origin of the power unit.
Possible reasons for refusal of registration
Despite the apparent simplicity of the procedure, there are risks of being denied registration of changes, the most common reason being that the engine does not meet safety requirements, if an inspector or expert determines that the engine installed is more powerful or has a different environmental class than the model allowed, registration will be denied until the changes are legalized through the laboratory, and the refusal will follow if the engine is listed on the federal wanted list as stolen.
Another common problem is that a one-digit engine number typo in a sales contract can be fatal. Inspectors are extremely picky about details, and any discrepancies between the metal number and the paper number are interpreted in favor of the law, that is, in the direction of refusal.
If the engine is found to be leaking, making extraneous sounds, having damage to the body or its exhaust system does not comply with the norms (for example, there is no catalyst if it is designed), this can be a reason for failure. The car must be technically correct. In addition, if the color of the car in the documents does not correspond to the real (for example, the car is repainted, but not registered), this can also complicate the procedure, since the inspector will first require legalization of the color.
⚠️ Warning: Attempting to register an engine with broken numbers or traces of chemical etching will not only lead to a failure, but also to the withdrawal of the car to the parking lot until the circumstances are clarified.
The main guarantee of successful registration is the complete identity of the specifications of the new engine to the old one and the presence of a perfectly executed contract of sale with the correct unit number.
