A qualified approach to buying a contract engine

The engines that were already in use differ from the new units in that they can have different technical condition, which depends on the conditions of their operation on the first car. To register an installed contract engine in government agencies, documents are required for it with perfect filling.

You can buy a used engine in several ways. For example, you can go abroad and bring the contract engine yourself. Agree, it is reliable from the point of view that the unit is purchased with a guarantee of use not on Russian roads. But it's expensive and you need some knowledge about the engines. The announcement also sells contract engines, but the risk of buying a poor-quality product is great. The best way to purchase the right aggregate on the Internet from a solid company, for example, is http://daavto.ru/.

Contact motors from companies

Why is it profitable to buy from companies that supply engines from abroad? This purchase will be beneficial for a car enthusiast for several reasons:

• The engine is given a guarantee. You can return money or get a new unit if it breaks during the warranty period.
• The engine undergoes a pre-sale check. The engine is ready for installation.
• The availability of all documentation and its correct completion.

The company always has documents for registration of the Customs Declaration, which confirms the non-use of the engine on Russian roads. Any unit is sold with a contract of sale with the indication of the number, which will be required when designing a replacement engine in the SAI.

What you need to do when buying an engine

A close inspection of the unit is the first thing you need to do when buying. The appearance of the engine should be neat. On all parts of the engine should not be:

• Oil streaks;
• Corrosion;
• Dents;
• Cracks.

When inspecting the engine, it is necessary to pay attention to the valve cover and the fastening bolts. The lack of sealant under the lid and the marks on the bolt caps indicate that the engine was repaired either when buying abroad or in Russia before selling it. Such an assembly is better not to buy, because it is impossible to repair an imported engine to such a quality as the factory engine, even by first-class craftsmen.

After inspection and verification of documents, the contract engine must be checked on the diagnostic stand. The engine in good technical condition starts immediately, no problems should arise. The engine compression should not significantly differ from the set value when the car is released, otherwise the resource of the unit is significantly developed.
