General precautions
1. Disconnect the negative cable from the battery.
2. Remove the glow plugs to make it easier to turn the engine.
3. Unless otherwise stated, turn the engine in the normal direction.
4. Familiarize yourself with the requirements for tightening forces of threaded connections.
5. If equipped, mark the position of the CKP sensor before removing it.
6. Do not turn the crankshaft using the camshaft drive sprockets or devices.
7. Do not turn the crankshaft and camshaft with the timing chain removed.
8. After setting the valve timing, check the high-pressure fuel pump.
Valve timing installation procedures
Note: The timing chain can be replaced without removing the engine. Use the special tools from the list above. The new chain can be connected to the old one, put on the sprocket and then joined.
1. Bring the piston of the first cylinder [1] to the TDC position.
2. Insert the locking rod into the intake camshaft sprocket [2].
3. Make sure that the timing marks on the camshafts [3] and [4] are correctly aligned.
4. Before performing repair procedures, remove the tensioner assembly [5].
Note: The camshaft sprocket mounting bolts [6] cannot be reused and must be replaced with new ones.
5. After completing the repair work, install the tensioner [5].
The tightening force of the tensioner fastener is 80 Nm.
Tightening torque of the crankshaft pulley bolt [7]:
- Bolt classification 8.8 - 200 Nm + 90°;
- Bolt classification 10.9 - 325 Nm + 90°.
