Repair of a head of cylinders

Dismantling

 PERFORMANCE ORDER

    In sequence shown in drawing for 2–3 passes turn out bolts of fastening of a head of the block of cylinders.
    The special adaptation 09222 – 27300 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.

For storage of valves prepare the numbered polyethylene packages or containers.

    Пассатижами remove маслоотражательный a cap.

Do not use repeatedly маслоотражательный a cap.

Check

Head of the block of cylinders

 PERFORMANCE ORDER

    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. Remove scale, hermetic and a deposit. Compressed air blow channels for greasing.
    Metal ruler and щупом in six directions 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:

– On width of 0,03 mm;
– On length of 0,09 mm;
– On a diagonal of 0,012 mm.

Valves

 PERFORMANCE ORDER

    Wire brush clear the valve.
    Examine each valve on presence of deterioration, damages and deformation in zones And and In and, if necessary, repair or replace it. If the core end face is corroded or worn out, as required restore facets. This restoration should be limited by the minimum removal of metal.

Also check up a thickness of working edges.

Thickness of a working edge of the valve:

Inlet valves: 1,16 mm
Final valves: 1,30 mm

Valve spring

 PERFORMANCE ORDER

    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.

Length of a spring without loading: 39,14 mm
Length of a spring under loading of 21,4 kg: 32 mm
Maximum deviation of a spring from a vertical plane: no more than 1,5
Maximum permissible reduction of length:–1 mm
Maximum permissible deviation of a spring from a vertical plane: no more than 4

Directing plugs of the valve

Check up a backlash between a core and the directing plug of the valve. If the backlash exceeds maximum permissible value, replace directing plug of the valve with the plug of the increased repair size.

Backlash between a core and the directing plug of the valve:

Inlet valves: 0,022–0,067 mm
Final valves: 0,005–0,095 mm

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

Inlet valves: 0,1 mm
Final valves: 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.

Assemblage

  1. Before installation clear details.
  2. Apply a thin film engine oil on all surfaces of sliding.

 PERFORMANCE ORDER

    Establish a spring saddle. Using the special adaptation 09222 – 27200, 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 – 27300 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.
    Define a thickness of a lining of a head of cylinders:
      Measure выступание the piston established in ВМТ under the relation from the interfaced surface of the block of cylinders; Depending on size выступания the piston under the table choose a thickness of a lining. As size выступания the piston average value from eight measurements is necessary. Even if one measurement exceeds admissible limits, the thickness of a lining is necessary for choosing on the basis of measurement выступания this point.
    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.
    In the sequence shown in drawing tighten bolts of fastening of a head of cylinders. The inhaling moment: 50 Nm to tighten on a corner 120 .
