3.2.30. Start-up of the engine after repair and обкатка
PERFORMANCE ORDER
1. After the assemblage termination check up level of oil and cooling liquid twice.
2. At the turned out candles and the disconnected system of ignition turn коленвал till the moment of registration of pressure of oil the gauge.
3. Screw candles, dress tips of high-voltage wires and connect ignition system.
4. Start the engine. The engine should be started immediately, after the short time interval necessary for increase of pressure of fuel.

The prevention

If at the first start-up of the engine through throttle заслонку return flashes check up installation of ignition and correctness of assemblage газораспределительного the mechanism are observed.


5. Warm up the engine, watching closely occurrence of leaks of oil or a cooling liquid.
6. Stop the engine and check up levels of oil and cooling liquid.
7. Disperse the car from speed of 50 km/hour to 90 km/hour, release a pedal throttle заслонки, having braked the car the engine till the speed of 50 km/hour. Cycle a loop 10–12 times. Thus occurs extra earnings of piston rings to walls of cylinders. Once again check up oil and liquid levels.
8. Make a trip on 800 km, without subjecting the engine to the big loadings (move on low speed, periodically checking oil level). During the period обкатки the raised expense of oil is possible.
9. After run of 900-1100 km replace oil and the oil filter.
10. At run of subsequent several hundreds kilometres conduct the car in a normal mode, avoiding too big and too small loadings.

11. After 3300 km of run again replace oil and the oil filter then the engine is considered the past обкатку.
