Note. The camshafts can be turned without the risk of the valves colliding with the pistons when the crankshaft is brought to a position of 30°before TDC of the first cylinder.
Note. The timing chain can be replaced without dismantling the engine. Using the tools listed below, the new chain can be connected to the old chain, passed around the sprockets and minted.
Attention! If assembled incorrectly, the valves may collide with the piston crowns!
General information
Installation details of timing drive elements
1 - Setting marks for bringing the engine to the TDC position of the end of the compression stroke of the first cylinder; 2 - Rods with a diameter of 4 mm for fixing the camshafts; 3 - When installing the chain, make sure that the camshaft adjuster tabs are in position «delays».; 4 - The camshaft can be locked from turning with a key; 5 - Tightening the exhaust camshaft sprocket bolts (5) must be carried out with a force of 22 Nm (type A - TORX T30) or 20 Nm + 90° (type B - TORX T40); 6 - Plug tensioner; 7 - Plunger; 8 - Tensioner body; 9 - Pin with spring

- Do not turn the crankshaft and camshafts with the timing chain removed.
Servicing Timing Drive Components
1. Disconnect the negative cable from the battery.
2. For the purpose of simplification of cranking of the engine turn out all spark plugs.
3. Bring the crankshaft to the TDC position of the piston of the first cylinder (1).
4. Insert the locking rods into the camshafts (2) 4 mm in diameter.
5. When installing the chain, make sure that the camshaft adjuster lugs (3) were in position «delays».
Attention! If assembled incorrectly, the valves may collide with the piston crowns! 6. Locking the camshaft from turning can be done with a key (4).
7. Tightening the exhaust camshaft sprocket bolts (5) must be carried out with a force of 22 Nm (type A - TORX T30) or 20 Nm + 90° (type B - TORX T40).
Note. During repair work, type A bolts should be replaced with disposable type B bolts.
Note. The intake and exhaust camshaft sprocket mounting bolts are disposable and must be replaced without fail.
8. Before proceeding with the repair procedures, loosen the tensioner plug (6) for one full turn.
9. At the engine position 30°after TDC of the piston of the first cylinder, remove the tensioner assembly (see Section Timing chain tensioner).
10. Having completed the necessary reconditioning, install the tensioner.
11. Remove the tensioner spring-loaded plug (6).
12. Push plunger (7) into the tensioner (8) in the direction indicated by the arrow.
13. Install the tensioner housing and tighten it with a force of 80 Nm.
14. Install in the case (8) plunger (7).
15. Install remaining components (6) And (9) and tighten the plug to 40 Nm.
16. Do not forget to lubricate the central bolt of the crankshaft pulley and its washer before installation (s).
