1 – an inlet pipe; 2 – a sealing ring; 3 – the case throttle заслонки; 4 – the system valve рециркуляции; 5 – a bolt of fastening of the case throttle заслонки;

6 – a branch pipe of the case throttle заслонки; 7 – a lining; 8 – a bolt of fastening of a connecting pipe; 9 – a final collector; 10 – a nut of fastening of a connecting pipe; 11 – a connecting pipe

Valve check рециркуляции the diesel engine of 1,9 l, 74 kw

1 – the valve рециркуляции; 2 – the case throttle заслонки; 3 – throttle заслонка; 4 – a valve rod; 5 – the vacuum pump

Valve check

PERFORMANCE ORDER

1. Remove an engine casing (subsection 2.1 see). 2. Disconnect a vacuum hose from the union of the valve 4 (fig. of the Detail of system рециркуляции the diesel engine of 1,9 l, 74 kw see) рециркуляции systems. 3. Ослабьте an inhaling of a collar also disconnect an air line from the case 3 throttle заслонки. 4. Connect to the union of the valve 1 (fig. valve Check рециркуляции the diesel engine of 1,9 l, 74 kw see) the vacuum pump 5. 5. By means of the pump create depression in the valve. The rod 4 valves should move upwards, and after a detachment of the vacuum pump to return to a starting position. Otherwise the valve is faulty also it it is necessary to replace.

Removal and installation of elements of system рециркуляции

The valve рециркуляции the fulfilled gases, established on the case throttle заслонки, represents with it not folding design. It is possible to replace the valve only together with the case throttle заслонки.

PERFORMANCE ORDER

1. Remove the top casing of the engine (subsection 2.1 see). 2. Disconnect a vacuum hose from the union of the valve 4 (fig. of the Detail of system рециркуляции the diesel engine of 1,9 l, 74 kw see) systems рециркуляции. 3. Ослабьте an inhaling of a collar also disconnect an air line from the case 3 throttle заслонки. 4. Turn away two bolts of 8 fastenings of a connecting pipe 11 to the case 3 throttle заслонки. 5. Turn away three bolts of 5 fastenings and remove the case 3 throttle заслонки with the valve 4. 6. For removal of a connecting pipe 11 turn on two nuts of 10 its fastenings to a final collector. 7. Replace linings 7 and a sealing ring 2 irrespective of their condition. 8. Establish system elements рециркуляции the fulfilled gases upside-down. Nuts of 10 fastenings of a connecting pipe to a final collector replace new. Grease hairpins of a final collector with graphite greasing.
