Removal the timing belt cover
The purpose of the cover is to prevent foreign particles from getting inside, as this could damage the operation of the timing belt. Dismantling is carried out as follows:
- unscrew the 4 hex screws of the cover;
- remove the cover.
The toothed belt cover can be removed after unscrewing four screws or nuts. Three of them (1-3) are visible in the picture here.
Checking the condition of the timing belt
(The original text is available on the portal: «VWmanual.ru»)
Remove the timing belt cover.
The toothed belt must be free of cracks and not oiled.
The surfaces of the teeth must be intact, without signs of wear.
The engine crankshaft should be rotated to check the condition of the timing belt along its entire length.
If the timing belt is damaged, it must be replaced!
Timing Belt Tension Control
The control is carried out simultaneously with the inspection of the condition of the toothed belt. A special device VW 210 is used. With the help of this measuring device, the belt tension is checked at a certain length. The measurement is made between the camshaft pulley and the fuel pump pulley.
Remove the cover from the timing belt.
Using a rubber mallet, lightly tap the belt between the camshaft pulley and the fuel pump pulley.
Place the measuring device and record the reading.
Turn the crankshaft once. Turn only by the crankshaft V-belt pulley with a special key or by the wheel with the gear engaged.
Repeat the measurement.
Calculate the average value of the measurements taken.
If the value on the scale is 12-13, then everything is fine. If the value is different, the belt should be tightened additionally.
Checking the tension of a toothed belt without a device
Remove the cover from the timing belt.
Use a rubber hammer to hit between the camshaft pulley and the fuel pump.
At the same place, press your finger to determine the belt deflection. If the tension is correct, the deflection is 10 mm. Otherwise, additional tension is required.
In case of doubt, repeat the measurement after turning the crankshaft again.
The timing belt tension should be checked again with a measuring device as soon as possible.
