The damper is located inside the front of the block head on the left and attached to it from the outside with two bolts
If the damper is worn or damaged, under certain engine operating conditions, resonant vibrations of the leading branch of the chain can occur, which can lead to chain jumping on the teeth of the camshaft sprocket and serious engine damage.
You will need: a screwdriver, a wrench (preferably a socket) "10".
Remove the cylinder head cover (see "Replacing the cylinder head cover gasket").
Remove the camshaft drive chain tensioner (see Replacing the camshaft drive chain tensioner).
With a chisel, we bend the edge of the lock washer of the camshaft sprocket bolt (for clarity, the hoses of the outlet pipe of the cooling jacket are disconnected).
Using a 17 spanner, unscrew the camshaft sprocket bolt
Remove the bolt together with the washers.
To loosen the chain tension, unscrew the nuts securing the hydraulic tensioner to the cylinder head
At the same time, we do not open the tensioner hydraulic drive tube.
To prevent the chain from jumping, we tie it to the sprocket and remove the sprocket with the chain from the camshaft (see "Checking and setting the valve timing by marks").
To prevent the chain from jumping, tie it to the sprocket and remove the sprocket with the chain from the camshaft.
Using a 10 spanner, unscrew the two bolts (of the same length) securing the chain damper to the cylinder head.
The bolt has a cylindrical shank for centering in the damper hole
Taking out the pacifier
When removing the damper, hold it securely with your hand, otherwise the damper that has fallen into the oil pan will be very difficult to remove.
Inspect the removed dampener.
If its working surface has a deep wear from the chain and chips, or there are cracks and breaks on the damper body, replace the damper.
Pay attention to the original shape of the damper - it differs from the dampers previously used on VAZ engines.
Purchase exactly the same sedative
Install the new damper in the reverse order of removal.
Install previously removed parts in reverse order.
