Check
Directing plugs of the valve
|
|

- Check up an end face of a core of the valve on a subject изъязвления and deterioration. If deterioration or изъязвление is found out, the end face of a core of the valve can be cleared repeatedly, but is not strong, so that not сошлифовывать its chamber. If it is worn out so strongly that its chamber is erased, replace the valve.
|
Width of contact прилегания
- Create drawing of an arrangement of contacts on each valve in the habitual image, i.e., having put a standard covering a marking mix on a valve cup, and a rotary motion пристукнув a cup of the valve with a valve head. It is necessary to use клапанный притирочный the machine tool (the tool used for grinding in of valves).
|
|
- The drawing printed on a contact surface of the valve should represent a continuous ring without any breaks, and the width of drawing should be in the specified limits. The standard width of contact formed by means of drawing of an arrangement of contacts on an obverse surface of the valve: on an admission on release — 1.1 – 1.3 mm (0.0433 – 0.0511 inches).
|
Repair of a cup of the valve
- The cup of the valve not creating full contact to the valve or showing width of contact прилегания, leaving for the specified range, should be repaired by repolishing or cutting and repolishing, and is ground to readiness by grinding in.
|
|
- CUP of the EXHAUST VALVE: Use a mill of a cup of the valve (1) to make two cuts. It is necessary to use two mills: the first to make a corner in 15 , and the second to make a corner in 45 . The second mill is necessary for using to receive necessary width of a cup. Width of a cup for a cup of the exhaust valve: 1.1 – 1.3 mm (0.0433 – 0.0511 inches).
|
- CUP of the INLET VALVE: Sequence of a cut precisely same, as for cups of the exhaust valve. Width of a cup for a cup of the inlet valve: 1.1 – 1.3 mm (0.0433 – 0.0511 inches).
|
|
- GRINDING in of VALVES: Grind in the valve to a cup (1) in two steps: at first by means of rough structure of a mix of grinding in of an obverse surface, and then by means of small structure of a mix, each time using the machine tool for grinding in of nests of valves according to a standard method of grinding in.

|
|
Cylinder head
|
|
- Remove all deposit from combustion chambers.
|
|
|
|
Do not use the sharp tool for соскребания a deposit. Be cautious not to make the tease or a groove on metal surfaces at соскребании a deposit. It also to concern and valves, and cups of valves. |
|
- Check up a head of the cylinder about cracks in inlet and final channels, combustion chambers, and on a head surface.
Планшетность the condensed surface:
|
|
- With the help калибромера check up a surface in 6 places. If the norm of deformation specified more low, is exceeded, correct the condensed surface with the help разметочной a plate and an abrasive paper #400 (a water-proof abrasive paper on the basis of silicon carbide): put a paper on разметочную a plate, and потрите the condensed surface about a paper, that сошлифовать high places. If it does not help to lower the indication калибромера to norm limits, replace a cylinder head. Leak of the working gases formed by products of combustion, from this condensed connection often occurs because of deformation of the condensed surface: such leak grows out of decrease in made capacity.
|
|
|
Limits of deformation of the condensed surface of a head of the cylinder: 0.05 mm (0.002 inches).
|
Deformation of surfaces прилегания a collector:
|
|
- Check up surfaces прилегания heads of the cylinder and collectors with the help калибромера, whether to define there is a necessity to correct these surfaces or to replace a cylinder head.
|
|
|
Limits of deformation of surfaces прилегания a collector: 0.10 mm (0.004 inches).
|
|
|
Klapannye springs
|
|
|
|
- Being based on the data given more low, be convinced that each spring is in a good condition, without breakage or easing certificates. Remember that weakened клапанные springs can cause jingle, not to mention possible decrease in made capacity because of the leak of gas caused by pressure decrease прилегания.
|
|
|
Length клапанной springs in a free condition:
- Norm: 36.83 mm (1.4500 inches)
- Limit: 35.67 mm (1.4043 inches)
Preliminary loading клапанной springs:
- Norm: 10.7 – 12.5 kg for 31.5 mm (23.6 – 27.5 pounds on 1.24 inches)
- Limit: 9.3 kg for 31.5 mm (20.5 pounds on 1.24 inches)
|
Perpendicularity of a spring:
|
|
- Use a square and разметочную a plate to check up each spring on perpendicularity from the point of view of a backlash between the end клапанной springs and a square. If the backlash is more than the limit specified more low, клапанные springs should be replaced. A perpendicularity limit клапанных springs: 2.0 mm (0.079 inches).
|
|
|
