The damper is located inside the front part of the cylinder head on the left and is attached to it from the outside with two bolts
If the damper is worn or damaged, resonant vibrations of the leading branch of the chain may occur in some engine operating modes, which can lead to the chain jumping on the teeth of the camshaft sprocket and serious engine damage.
Remove the sprocket with the chain from the toe of the camshaft for this:
With a chisel bend back the edge of the lock washer of the camshaft sprocket mounting bolt (for clarity, the hoses of the cooling jacket outlet pipe are disconnected).
Use a 17 mm open-end wrench to loosen the camshaft sprocket mounting bolt.
Remove the bolt together with the washers.
To loosen the chain tension, unscrew the nuts securing the hydraulic tensioner to the cylinder head (see Replacing the tensioner Niva Chevrolet).
Do not disconnect the tensioner hydraulic tube.
To prevent the chain from jumping, tie it to the sprocket and remove the sprocket with the chain from the camshaft
Using a 10 mm socket, unscrew the two bolts (of the same length) securing the chain guide to the cylinder head
The bolt has a cylindrical shank for centering in the hole in the guide
Remove the damper
Install the damper in the reverse order
