Removal and installation of camshafts

1. Remove the engine covers, refer to the appropriate section.
2. Remove the nozzle, refer to Section Removal and installation of atomizers.
3. Remove the cylinder head cover, refer to the appropriate section.
4. Set the first cylinder to TDC.

5. Secure the intake camshaft. To do this, insert the locking pin (1) through the cover of the first bearing in the camshaft sprocket hole in the shaft of inlet valves (2).

6. Remove the chain tensioner, refer to the appropriate section.
7. Remove the front cover, refer to the appropriate section.
8. Remove the upper slide guide, refer to the appropriate section.
9. Mark camshaft sprocket towards the chain.

If, during subsequent works camshaft should not rotate, tie connector cable sprocket and chain.

10. Remove the asterisk from the exhaust camshaft and remove it. At the same time aware of the guide pin. Remove an asterisk together with a chain.

Engine 611: Remove the camshaft bearing caps: ?� Remove the cover bolts E1, E3, E5 and A1, A3 and A5. At the same time pay attention to the marking of caps for installation. ?� Loosen the screws of bearing caps E2, E4 and A2, A4 in stages, each time for one revolution so that counterpressure remove the camshaft. Make sure that when loosening bolts camshafts are not skewed. Fully unscrew the bolts and remove the cover.

Engine 612: Remove the camshaft bearing caps as follows: ?� Remove the cover bolts E1, E3, E4, E6, and the A1, A3, A4 and A6. At the same time pay attention to the marking of caps for installation. ?� Loosen the screws of bearing caps E2, E5 and A2, A5 in stages, each time for one revolution so that counterpressure remove the camshaft. Make sure that when loosening bolts camshafts are not skewed. Fully unscrew the bolts and remove the cover.

13. Remove the camshafts intake and exhaust valves.

1. Grease a pusher, and basic necks of camshafts clean motor oil. Check the ease of a push rod stroke.
2. Install the camshafts intake and exhaust valves and set them on the thrust bearings. At the same time pay attention to the location of the shaft. Marking shafts affixed at a point of contact with the thrust bearing.

01 inlet camshaft
00 exhaust camshaft.

3. Install the camshafts so that the holes (3) in the camshaft sprockets are against each other and match marking the camshaft and bearing caps. The camshafts are very sensitive to overvoltages and could be destroyed. Therefore, take care to installation does not lead to an overload of shafts.

4. Turn the crankshaft in the opposite direction to the position of the piston of the first cylinder 30 ?� before TDC.

5. Install the bearing caps according to their labeling. Bearing caps are asymmetrical. Make sure that they were not biased.

?� Tighten the caps E2, E4; A2 and A4 in stages, each time for one revolution. Tighten the cap torque 9Nm. Make sure that when tightening the screws not to warp the camshafts.
?� Tighten bearing caps E1, E2, E5, and the A1, A3, A5 9Nm moment.

8. Establish the piston of the first cylinder to TDC.
9. Secure the intake camshaft. To do this, insert the locking pin through the cover of the first bearing in the hole in the inlet camshaft sprocket.
10. Install chain sprocket on the intake camshaft, while pay attention to the guide pin.
11. Attach the new sprocket bolts to 18Nm. If necessary, cut off and remove the connector cable.
12. Install the top guide, refer to the appropriate section.
13. Install chain tensioner with a new seal, refer to the appropriate section.
17. Replace the engine covers, refer to the appropriate section.
