- To turn away a nut of a connector of pistons and to remove the piston 5 with a diaphragm 7, a plate and a persistent ring;

- To remove the amplifier from the adaptation and to take from the case a persistent cover and other details of the amplifier, to take a lock washer and to take out from a connector a pusher;

- To turn away three bolts with spring washers and to remove a connector, the piston 10 with a diaphragm 8 and a diaphragm 18 with a spring. To take out from the piston 10 jet rubber washer 20; to turn out two screws 19, 17 pushers fixing the piston in the case of 15 valves, and to take out a pusher with the piston;

- To turn away a pusher eye, preliminary having weakened a counternut;

- Slightly to compress a pusher spring, to take out a lock washer and to remove other details from a pusher. The pusher with the piston is not folding connection. To take out lock washers and to take from a persistent cover and the case 11 amplifiers directing plastic rings 12, and also sealing rubber cuffs 13;

- To remove from a connector of pistons a sealing rubber ring;

- To take out the return valve 1 of a cover of the case and if necessary to replace it.

All details of the amplifier to clear of a dirt and to examine. The details having damages or excessive deterioration to replace. It is necessary to give special attention to check of rubber details of the amplifier, and also a condition of the external polished surfaces of a connector of pistons and cases of 15 valves. In the presence of scratches and задиров these surfaces should be smoothed out accurately a small skin and to wash out.

If the filter 14 is littered, it is necessary to replace it.

Before assemblage all details of the amplifier should be absolutely pure. If necessary all details, except for rubber, it is possible to wash out in pure kerosene and to dry up a stream of compressed air.

To collect the amplifier follows in sequence, return dismantling.

At assemblage it is necessary to consider following features:

- In the case of 15 valves it is necessary to grease a rubber sealing ring with greasing ЦИАТИМ-221;

- After installation of sealing cuffs 13 in the case and a persistent cover to grease their internal surfaces with a thin layer of greasing ЦИАТИМ-221;

- To establish the collected pusher with the piston in the case of 15 valves. Slightly to press a pusher, overcoming resistance of a spring, and to screw two fixing screws 19. Screws to wrap against the stop, then to turn on on 0,5 turns everyone and закернить them for prevention отворачивания. The pusher with the piston should move without jammings and warps on 1—2 mm;

- The external polished surfaces of a connector of pistons and the case of 15 valves before assemblage to grease with a thin layer of greasing ЦИАТИМ-221;

— A surface of diaphragms 7 and 8 before assemblage to cover with a thin layer of talc, and a flute of a fillet of a diaphragm 7 for simplification of turn of a cover concerning the case to grease with a thin layer касторового oils or liquid НГ-213;

- Diaphragm 7 at assemblage to straighten so that its fillet has come for ledges on the case of the amplifier and has nestled on internal diameter of the case;

- Nut, крепящую the piston 5 to tighten the moment 5,5—8 Н·м (0,55 0,8 кгс·м);

- Inserting a cover 6 into the case 11, to watch, that the diaphragm 7 was not wrapped.

After assemblage to check up working capacity of the amplifier in a following order:

- To connect the return valve of 1 amplifier a hose to a depression source, for example, with an inlet pipe of the working engine; the end of a tube 2 (fig. 8.9 see) in заглушке 5 to connect a hose to the vacuum gauge;
