Valve check

PERFORMANCE ORDER
1. Remove an engine casing (see subsection 2.1).
2. Disconnect a vacuum hose from the valve 4 union (see rice. Detail of system of recirculation of the diesel engine of 1,9 l, 74 kW) of recirculation of system.
3. Weaken an inhaling of a collar and disconnect an air duct from the case 3 of a butterfly valve.
4. Connect to the valve 1 union (see rice. Valve check of recirculation of the diesel engine of 1,9 l, 74 kW) vacuum pump 5.
5. By means of the pump create depression in the valve. The rod 4 valves has to move up, and after a detachment of the vacuum pump to return to a starting position. Otherwise the valve is faulty and it needs to be replaced.

Removal and installation of elements of system of recirculation

The valve of recirculation of the fulfilled gases installed on the case of a butterfly valve represents with it a non-demountable design. The valve can be replaced only together with the case of a butterfly valve.

PERFORMANCE ORDER
1. Remove the top casing of the engine (see subsection 2.1).
2. Disconnect a vacuum hose from the valve 4 union (see rice. Detail of system of recirculation of the diesel engine of 1,9 l, 74 kW) of system of recirculation.
3. Weaken an inhaling of a collar and disconnect an air duct from the case 3 of a butterfly valve.
4. Turn off two bolts of the 8th fastening of a connecting pipe 11 to the case 3 of a butterfly valve.
5. Turn off three bolts of the 5th fastening and remove the case 3 of a butterfly valve with the valve 4.
6. For removal of a connecting pipe 11 turn off two nuts of the 10th its fastening to a final collector.
7. Replace laying 7 and a sealing ring 2 irrespective of their state.
8. Establish elements of system of recirculation of the fulfilled gases upside-down. Replace nuts of the 10th fastening of a connecting pipe to a final collector new. Grease hairpins of a final collector with graphite lubricant.
