The special adaptation 09222 – 28000, 09222–28100 compress a spring of the valve and remove from a core of the valve crackers. Slowly release the adaptation compressing a spring, and remove a valve spring, a plate of a spring and the valve from a head of the block of cylinders.

Examine a head of the block of cylinders on absence of damages, cracks, leaks of oil and cooling liquid. If necessary, replace a head of cylinders.

Metal ruler and щупом in six directions A, B... Check up planeness of a head of the block of cylinders. If necessary, перешлифуйте a head of the block of cylinders.

Standard deviation from planeness: less than 0,03 mm.
Maximum permissible deviation from planeness: 0,05 mm.

Also check up a thickness of working edges.

Thickness of a working edge of the valve:

Inlet valves: 1,15 mm:

- Engines of 1,8 and 2,0 l: 1,15 mm;
- Engines of 1,6 l: 1,1 mm.

Final valves:

- Engines of 1,8 and 2,0 l: 1,35 mm;
- Engines of 1,6 l: 1,3 mm.

Maximum permissible thickness of a working edge of the valve:

Inlet valves: 0,8 mm;
Final valves: 1,0 mm.

Examine each spring of the valve on absence of cracks and damages. Measure length of a spring in a free condition. Establish a spring on a flat horizontal surface and measure a deviation of the top part of a spring from a vertical plane.

After removal of an old saddle of the valve it is necessary to chisel a nest under the increased size of a saddle of the valve. The sizes for processing are resulted in the table.

The increased sizes of a plug-in saddle of the valve of engines 1,8 and 2,0 л³

The increased sizes of a plug-in saddle of the valve of engines of 1,6 l

Heat up a head of cylinders to temperature 250C and запрессуйте a new saddle of the valve of the repair size. At запрессовке the valve saddle should have a room temperature. After installation of a new saddle of the valve it is necessary to execute valve grinding in. The width of a working facet of a saddle of the valve should be within technical requirements.

Width of a working facet of a saddle of the inlet valve:

- Engines of 1,8 and 2,0 l: 1,1–1,5 mm;
- Engines of 1,6 l: 0,8–1,2 mm.

Width of a working facet of a saddle of the final valve: 1,3–1,7 mm

Using the adaptation 09221 – 22000 A/B выпрессуйте the plug of the valve from a head of cylinders in a direction to the block of cylinders. Put to an aperture of a head of cylinders the new directing plug of the valve of the increased repair size.

After запрессовки directing plugs of valves insert new valves and check up a backlash. Each time at replacement of directing plugs of valves check up and, if necessary, replace saddles of valves.

The increased sizes of the directing plug of the valve

Establish a spring saddle. Using the special adaptation 09222 – 22001, establish маслоотражательный a cap.

Establish springs and holders of springs. Springs are necessary for establishing the party covered with enamel, to holders of springs.

Clear all привалочные surfaces of the block of cylinders and a head of the block of the cylinder. Check up marks presence on a lining of a head of cylinders. Establish a new lining of a head of the block of cylinders so that the surface with marks has been directed to a head of cylinders.

The moment of an inhaling of bolts of fastening of a head of cylinders of engines of 1,8 and 2,0 l

М10: 25 Nm to tighten on a corner 60–65 to tighten on a corner 60–65
М12: 30 Nm to tighten on a corner 60–65 to tighten on a corner 60–65

The moment of an inhaling of bolts of fastening of a head of cylinders of engines of 1,6 l:

30 Nm to tighten on a corner 90 to weaken all bolts 30 Nm to tighten on a corner 90
