Withdrawal
1. Remove the top part of the toothed belt guard.
2. Set the crankshaft to TDC on the piston of cylinder No. 1.
3. Remove the toothed belt gear. When unscrewing the pinion fixing bolt, keep it from turning, for example, using a locking device 3036). For six-cylinder engines, remove the toothed belt gear with a puller.
4. Remove the cylinder head.
5. Loosen the toothed belt tension and remove it from the camshaft gear.
6. Disconnect the vacuum brake booster pump mounted on the cylinder head (only five-cylinder engines).
7. Disconnect the Hall sensor on the left cylinder head of the six-cylinder engine.
8. 4- and 5-cylinder engines. Remove bearing caps 1 and 3 first (when viewed from the front), then covers 2 and 4, working in a cross order.
9. 6-cylinder engine. First remove bearing caps 2 and 3 (when viewed from the front), and then 1 and 4, also acting in a cross order.
Installation
Install the camshaft as follows:
10. 4 and 5-cylinder engines. Install the camshaft in place so that the cams of the piston of cylinder No. 1 face evenly up.
11. 6-cylinder engine. Reinstall the camshaft with the larger hole in the lock plate facing the opposite cylinder head. When reinstalling the driveshaft bearing caps, be sure that the hole in the caps is not centered on all engines.
12. Establish covers of bearings of a camshaft into place, being guided by corresponding marking.
13. 4- and 5-cylinder engines. First tighten the bolts of covers 2 and 4 in a cross order, and then of covers 1 and 3. The tightening torque is 20 Nm.
14. 6-cylinder engines. First tighten the bolts of covers 1 and 4 in a crosswise order, and then of covers 2 and 3. The tightening torque is 20 Nm.
15. 4- and 5-cylinder engines. Camshaft gear (if filmed) tighten with a torque of 65 Nm. When reinstalling the gear, make sure that the wedge on the shaft fits into the hole in the gear.
16. 6-cylinder engine. Install the camshaft gear together with the lock plate and tighten to 70 Nm.
17. All engines. Check without fail the adjustment of the gas distribution mechanism.
18. Start the engine not earlier than 30 minutes after installing the camshaft. This time is necessary for «sat down» hydraulic pushers.
