Check and adjustment of backlashes of valves on engines of 1,8 and 2,0 l (MLA)

 PERFORMANCE ORDER

Check and adjustment of backlashes of valves spend on the cold engine (temperature of a cooling liquid 21С) and the head of cylinders established on the block of cylinders.

    Remove from the engine a casing.
    Uncover with маслоналивной mouths.
    Turn out screws and remove the central cover.
    Remove the top casing of a gear belt.
      Turn out bolts of fastening of the top casing of a gear belt and remove it.
    Uncover heads of cylinders.
      Disconnect high-voltage wires, thus do not put to them considerable efforts. Disconnect from a head of cylinders a ventilation hose картера. Disconnect from a head of cylinders an accelerator cable. Turn out bolts of fastening of a cover of a head of cylinders and uncover also a lining.

At applying of considerable efforts or a bend of high-voltage wires probably damage of the central vein of a wire.

    Establish the piston in the first cylinder in the top dead point in a compression step.
      Turn a cranked shaft clockwise and combine a groove on a pulley with a label T on the bottom casing of a gear belt.

b. Check up that the aperture on a camshaft pulley is combined with a label on a bearing cover, otherwise, turn a cranked shaft on one turn (360 ).

    Check up клапанные backlashes.
      Check up only клапанные the backlashes shown in drawing (the piston in the first cylinder is established in ВМТ in a compression step).
    Flat щупом measure a backlash between an adjusting lining of a pusher and the basis of a cam of a camshaft. Write down value of the measured backlash. This value буде is necessary for calculation of a demanded thickness of an adjusting lining.

Klapannyj backlash (temperature of a cooling liquid 20C):

– Inlet valves: 0,20 mm;
– Final valves: 0,28 mm.

Klapannyj backlash (temperature of a cooling liquid 80C):

– Inlet valves: 0,29 mm;
– Final valves: 0,34 mm.

Maximum permissible клапанный a backlash:

– Inlet valves: 0,12–0,28 mm;
– Final valves: 0,20–0,36 mm.

b. Turn a cranked shaft on one turn (360 ) clockwise and combine a groove on a pulley with a label T on the bottom casing of a gear belt.

c. Check up only клапанные the backlashes shown in drawing (the piston in the first cylinder is established in ВМТ in a compression step).

    Flat щупом measure a backlash between an adjusting lining of a pusher and the basis of a cam of a camshaft. Write down value of the measured backlash. This value will be necessary for calculation of a demanded thickness of an adjusting lining.
    Adjust backlashes of inlet and final valves.
      Turn a cranked shaft so that the contour of a cam of a camshaft on the adjusted valve has been directed upwards.

b. The special tool (09220 – 2D000) press a valve pusher, insert a stopper between a camshaft and a pusher and remove the special tool.

c. A small screw-driver or a magnet get an adjusting lining.

d. By a micrometer measure a thickness of the removed adjusting lining.
e. Calculate a thickness of a new adjusting lining so that клапанный the backlash was in limits of the set size.

Klapannyj backlash (temperature of a cooling liquid 20C)

T: the Thickness of the removed adjusting lining
A: Measured клапанный a backlash
N: the Thickness of a new adjusting lining
Inlet valves: N = T (And – 0,20 mm)
Final valves: N = T (And – 0,28 mm)

f. Choose a new adjusting lining with a thickness of the closest to the calculated value.

As spare parts adjusting linings of 20 sizes with a thickness, from 2,00 mm to 2,76 mm with step of 0,04 mm are delivered.

g. Establish a new adjusting lining on a valve pusher.
h. The special tool (09220 – 2D000) press a pusher of the valve and remove a stopper.
i. Repeatedly check up клапанный a backlash.

Klapannyj backlash (temperature of a cooling liquid 20C):

– Inlet valves: 0,20 mm;
– Final valves: 0,28 mm.

Maximum permissible клапанный a backlash:

– Inlet valves: 0,17–0,23 mm;
– Final valves: 0,25–0,31 mm.
