General Precautions
1. Disconnect the negative cable from the battery.
2. Turn out glow plugs for the purpose of simplification of cranking of the engine.
3. Unless otherwise noted, turn the engine in the normal direction.
4. Familiarize yourself with the torque requirements for threaded connections.
5. If equipped, mark the position of the CKP sensor before removing it.
6. Do not rotate the crankshaft using camshaft drive sprockets or devices.
7. Do not turn the crankshaft or camshaft with the timing chain removed.
8. After installing the valve timing, check the injection pump.
Valve Timing Procedures
Note. The timing chain can be replaced without dismantling the engine. Use the special tools listed above. The new chain can be connected to the old one, draped over the sprocket and then docked.
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 alignment marks of the camshafts [3] and [4] are aligned correctly.
4. Before proceeding with the repair procedures, remove the tensioner assembly [5].
Note. The camshaft sprocket bolts [6] cannot be reused and must be replaced with new ones.
5. After completing the repairs, install the tensioner [5].
The tightening force of the tensioner fasteners is 80Nm.
Tightening torque of the crankshaft pulley bolt [7]:
- Bolt classification 8.8 - 200 Nm + 90°;
- Bolt classification 10.9 - 325 Nm + 90°.
