Check and adjustment of gaps of valves carry out on the cold engine (temperature of cooling liquid 21°С) and the head of cylinders established on the block of cylinders. |
|
|
Remove from the engine a casing.
|
|
|
Uncover a maslonalivny mouth.
|
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 hose of ventilation of a case.
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 laying.
|
|
During the applying of considerable efforts or a bend of high-voltage wires possibly injury 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 well-aimed «T» on the bottom casing of a gear belt.
|
|
|
b. Check that the opening on a pulley of a camshaft is combined with a label on a bearing cover, otherwise, turn a cranked shaft on one turn (360 °).
|
Check klapanny gaps.
Check only klapanny gaps shown in drawing (the piston in the first cylinder is established in VMT in a compression step).
Flat shchupy measure a gap between adjusting laying of a pusher and the basis of a cam of a camshaft.
Write down value of the measured gap. This value awaking it is necessary for calculation of the demanded thickness of adjusting laying.
Klapanny gap (temperature of cooling liquid 20°C):
– inlet valves: 0,20 mm;
– final valves: 0,28 mm.
Klapanny gap (temperature of cooling liquid 80°C):
– inlet valves: 0,29 mm;
– final valves: 0,34 mm.
Maximum permissible klapanny gap:
– 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 well-aimed «T» on the bottom casing of a gear belt.
|
|
|
c. Check only klapanny gaps shown in drawing (the piston in the first cylinder is established in VMT in a compression step).
|
Flat shchupy measure a gap between adjusting laying of a pusher and the basis of a cam of a camshaft.
Write down value of the measured gap. This value will be necessary for calculation of the demanded thickness of adjusting laying.
|
|
Adjust gaps of inlet and final valves.
Turn a cranked shaft so that the contour of a cam of a camshaft on the adjusted valve was directed up.
|
|
|
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 adjusting laying.
|
d. By a micrometer measure thickness of the removed adjusting laying.
e. Calculate thickness of new adjusting laying so that the klapanny gap was in limits of the set size.
Klapanny gap (temperature of cooling liquid 20°C)
T: Thickness of the removed adjusting laying
A: The measured klapanny gap
N: Thickness of new adjusting laying
Inlet valves: N= T + (And – 0,20 mm)
Final valves: N= T + (And – 0,28 mm)
f. Choose new adjusting laying with a thickness of the closest to the calculated value.
|
|
As spare parts adjusting laying of 20 sizes with a thickness, from 2,00 mm to 2,76 mm with a step of 0,04 mm is delivered. |
g. Establish new adjusting laying on a valve pusher.
h. The special tool (09220 – 2D000) press a pusher of the valve and remove a stopper.
i. Repeatedly check a klapanny gap.
Klapanny gap (temperature of cooling liquid 20°C):
– inlet valves: 0,20 mm;
– final valves: 0,28 mm.
Maximum permissible klapanny gap:
– inlet valves: 0,17–0,23 mm;
– final valves: 0,25–0,31 mm.
