Check and adjustment
1. Remove the air filter.
2. Remove the ignition coils and cylinder head cover.
3. Turn the crankshaft until the alignment mark is aligned with the pointer on the timing belt cover.
4. Make sure that the alignment marks of the camshaft gears match, otherwise turn the crankshaft one turn.
5. Using a feeler gauge, check the valve clearances shown in the figure.
6. Rotate the crankshaft one turn and check the valve clearances shown in the figure.
Rated Clearance:
- intake valves - 0.18 + 0.05 mm
- exhaust valves - 0.25±0.05 mm
Note: Write down the number of the valve whose clearance differs from the nominal value and the clearance value of this valve.
7. If the gap differs from the nominal, replace the adjusting washers.
A) Turn the crankshaft, install the valve lifter with the notch inward, with the cam pointing up.
b) Turn the crankshaft, set the camshaft cam down, while drowning the valve down.
V) Install the special tool on the pusher from the inside, as shown in the figure. Turn the crankshaft and install the camshaft with the cam up, while the pushrod should be recessed down with the special tool.
G) Using a magnetic rod and a small screwdriver, pry out the shim.
d) Using a micrometer, measure the thickness of the removed washer.
e) Calculate the thickness of the new shim using the following formula:
A = B + (C - D)
- A is the thickness of the new pusher,
- B is the thickness of the removed pusher,
- C - measured clearance in this valve,
- D - average value of the nominal clearance (0.18 mm for intake valve and 0.25 mm for exhaust).
Note: shims are available in 41 sizes in 0.02 mm increments from 2.50 mm thick (№30) up to 3.30 mm (№70). The designation of the thickness of the washer is embossed on its inner side.
and) Install a new shim with the mark down.
h) Rotate the crankshaft with the camshaft cam down, remove the special tool.
8. Install a new gasket on «cylinder head seal, apply sealant in the areas shown in the figure.
9. Install the cylinder head cover and ignition coils.
10. Install the air filter.
