Final the valve: 0,05–0,08 mm

Maximum permissible backlash between a core and the directing plug of the valve:

Inlet the valve: 0,1 mm
Final the valve: 0,15 mm

Plug-in saddle of the valve

Check up a valve saddle on presence of an overheat and infringement of the working surface contacting to a plate of the valve. If necessary repair or replace a valve saddle.

Before replacement or repair of a saddle of the valve check up deterioration of the directing plug of the valve. If the directing plug of the valve is worn out, replace it.

Replacement of a saddle of the valve

 PERFORMANCE ORDER

Any plug-in saddle of the valve which has been worn out to a limit, it is necessary to replace at a room temperature with wall cutting, as is shown in drawing.
    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.

    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

Replacement of the directing plug of the valve


 PERFORMANCE ORDER

    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.
    The adaptation for installation of the directing plug of the valve 09221–22000 A/B запрессуйте the plug in a head of cylinders. The adaptation provides запрессовку plugs on strictly certain depth. Measure выступание the top part of the directing plug of the valve from a head of cylinders. Pay attention that выступание the directing plug of the valve variously for inlet and final valves.
    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.

Assemblage

 PERFORMANCE ORDER

  1. Before installation clear all details.
  2. Apply a thin film engine oil on all surfaces of sliding.
    Establish a spring saddle. Using the special adaptation 09222 – 22001, establish маслоотражательный a cap.
  1. Do not use repeatedly old маслоотражательные caps.
  2. Wrong installation маслоотражательного a cap adversely influences its working edge for the account эксцентриситета and leads to engine oil leak through directing plugs of the valve.
At installation be cautious not to overwind маслоотражательный a cap.
    Grease a core of the valve with engine oil and establish the valve. At installation of the valve do not apply the big efforts not to damage маслоотражательный a cap. Check up smoothness of moving of the valve.
    Establish springs and holders of springs. Springs are necessary for establishing the party covered with enamel, to holders of springs.
    The special adaptation 09222 – 28000, 09222–28100 compress a spring. Establish crackers and remove the special adaptation for spring compression.

At spring compression be convinced that маслоотражательный the cap is not clamped by the adaptation for spring compression.

    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.
