Extraneous sounds of the circuit may have the following reasons:
- Poor plunger purge.
- Worn plunger. Clogged airflow slot (ventilation slot).
- Ball valve defective.
- Too little or too much spring force.
Withdrawal
Loosen the plunger locking bolt.
Attention: The bolt is under strong spring pressure.
Remove the chain tensioner spring and plunger.
Examination
Measure the free length of the spring. It should be 155.5 mm.
To make sure the ball (H) moves freely, shake the plunger (TO).
Check valve operation. To do this, it is necessary to blow compressed air into the plunger from the side indicated in the figure by the number 1, while the valve should open. When air is blown in direction 2, the valve should close.
Otherwise, knock out the valve (F) from the sleeve (G) and clear it. Please note that the airflow slot (1) was clean.
Installation
Pour about 100 cm of oil into the hole in the engine block
Install the plunger with spring and new O-ring and screw on the locking bolt by hand.
Attention: The conical end of the spring must point towards the bolt.
After unscrewing the mounting bolts, remove the cylinder head cover and the camshaft gear cover.
Move the tensioner in both directions until oil appears at the locking bolt and resistance is felt.
Tighten the locking bolt to 35 Nm.
Install the cylinder head cover and camshaft gear cover.
