A contract engine is a used engine from Japan or Europe that has no run in Russia. Usually they are removed from damaged or decommissioned vehicles that cannot be repaired. Contract engines are delivered complete with all attachments, which allows you to easily install it on the car.
Instructions
Step 1
To select a contract engine, find out as precisely as possible the model, equipment, year of manufacture and model of the car for which it is intended. The fact is that for Japanese engines, the same power units can differ depending on the car and the market for which they were intended. With each year of release, very significant changes could be made to the motor model.
Step 2
Choose your method of purchasing a contract engine. To do this, you can independently go to Japan or Europe, find, select and purchase the desired product. With substantial knowledge of engine design and a fair amount of luck, you can buy a great engine for ridiculous money. Even if there is little knowledge and experience, the choice of presented contract motors will be simply huge.
Step 3
If you do not want to travel abroad on your own, purchase a contract engine from a specialized company with a good reputation and extensive work experience. Competent sellers will help you determine the required motor model and give advice on installation and operation. Many firms, in addition to selection and sale services, offer the installation of goods purchased from them with a good discount. However, when choosing a company, be guided not only by the cost of the proposed unit.
Step 4
Pay attention to the warranty for the contract motor. As a rule, the best firms give a 6-month warranty on the contract engine. The presence of a guarantee means that the company responsibly approached the choice of the power unit, carried out its diagnostics and some pre-sale preparation related to the replacement of defective parts. The lack of a guarantee for the offered product should be alarming. Look for another firm.
Step 5
Please note that in most cases the warranty only covers product inspection. This means that if no defects are found after correct installation and inspection of the engine, the warranty has been fulfilled. It is believed that if a contract engine works normally immediately after installation, then it will also work for many years to come, subject to regular and timely maintenance.
Step 6
Pay attention to the delivery time of the goods. They usually depend on the model of the contract engine and the scheme used by the firm. Engines of 1990-2000 production heads are delivered the fastest, and with older and younger ones it is more difficult. In addition, it is almost impossible to find a contract engine for a rare car. The standard delivery scheme, in which, after receiving the order, the company first looks for an engine, then buys it, delivers and clears customs is too slow. The term of order fulfillment lasts from 1-2 months to six months or more.
Step 7
Choose firms that have their own warehouses for contract engines. This scheme provides for a stock of the most popular motors in stock and restocking as they run out. In this case, the delivery time will not exceed several days. The only problem will be units for rare cars.
Step 8
With some knowledge and experience, test the reliability of the engine. Start it up first. If it won't start, ditch that option, even if it's offered at a super low price. Then look at the engine mileage meter. In Europe and Japan, it is not customary to twist the meter, however, intermediaries from among the Russians can sin with this. Remove the sump and assess the color of the oil. Carry out a visual inspection with the cylinder head cover removed. If possible, check the engine on the stand. Measure the compression in the cylinders. A half-unit deviation from factory compression for a contract motor is an excellent result.
Step 9
Check the accompanying documentation for the engine, comparing all numbers and names with real ones. Discrepancies can also be unintentional, occurring as a result of errors of performers. But these discrepancies can bring trouble when installing the motor or registering it with the traffic police.
