5.11.3. Replacement of oil scraper caps

External sign of wear of oil scraper caps is short-term emergence of blue smoke from an exhaust pipe after launch of the engine and when braking by the engine after the long movement under loading. At the same time constant smoking usually is not observed. Indirect signs — the increased oil consumption in the absence of external leaks and greasy electrodes of spark plugs.
It will be required to you: all tools necessary for removal of a cover of a head of the block of cylinders (see. "Replacement of laying of a cover of a head of the block of cylinders"), the drive of the gas-distributing mechanism (see. "Replacement of a belt of the drive of the gas-distributing mechanism and a tension roller"), a back cover of a belt of the drive of the gas-distributing mechanism (see. "Replacement of laying of a head of the block of cylinders"), removals of a head of the block of cylinders (see. "Replacement of laying of a head of the block of cylinders"), and also tweezers (or the magnetized screw-driver) for extraction of crackers from plates of springs of valves …
… device for compression of springs of valves …
… device for removal and mandrel for installation of oil scraper caps.
1. Disconnect a wire of the minus plug of the rechargeable battery.
2. Turn out spark plugs (see. "Replacement and service of spark plugs").
3. Install the piston of the 1st cylinder in the provision of VMT of a step of compression (see. "Installation of the piston of the first cylinder in the provision of VMT of a step of compression").
4. Take off a belt of the drive of the gas-distributing mechanism (see. "Replacement of a belt of the drive of the gas-distributing mechanism and tension roller").
5. Remove pulleys of camshafts (see. "Replacement of laying of a head of the block of cylinders").
6. Remove a back protective cover of a belt of the drive of the gas-distributing mechanism (see. "Replacement of laying of a head of the block of cylinders").
7. Uncover a head of the block of cylinders (see. "Replacement of laying of a cover of a head of the block of cylinders").
8. Remove a block head (see. "Replacement of laying of a head of the block of cylinders").
9. Turn out a face head "on 8" twenty bolts of fastening of the case of bearings of camshafts...
10. … also remove the case.
11. Take out camshafts from support of a head of the block of cylinders.
12. Take hydropushers of valves from openings of a head of the block of cylinders.
13. Install the device for compression of springs of valves, having screwed a bolt of fastening of a cover of the bearing of the camshaft in one of block head openings and having hooked on adaptation for this bolt. Squeeze adaptation a valve spring.
14. Take out two crackers from the top plate of a spring by means of tweezers or the magnetized screw-driver. Then remove adaptation.

Good advice
If the effort of movement of the lever of adaptation considerably increases, and crackers do not leave a valve pro-point, strike easy blow with the hammer to a plate of springs that crackers were released.

15. Remove a plate of a spring.
16. Remove a spring.
17. Press an oil scraper cap from the directing valve plug.

Prevention
In the absence of the device for removal of caps accurately remove their passatizham. The effort needs to be put strictly up and not to turn caps not to damage the directing plugs of valves. Application for this purpose of two screw-drivers is forbidden!

Good advice
If the adjusting plug is included in the package of new caps, put on it a valve core to protect from damages a working edge of a cap by keen edges the protocheck under crackers on a valve core.

18. Dip an oil scraper cap into engine oil and insert it into a mandrel.
19. Carefully press a cap against the stop.

Note
If on a core of the valve installed the directing plug, remove it.

20. Establish springs and plates of springs.
21. Squeezing a spring adaptation, establish crackers so that they rose in valve core pro-points.

Good advice
After installation of crackers and removal of device for compression of valvate springs strike several weak blows with the hammer to a valve core end face that crackers were with guarantee recorded in a core pro-point. If the crackers established with a distortion remain unrecorded, at launch of the rassukharenny engine the valve will fail in the cylinder that will lead to serious failure of the engine.

22. Establish a valve hydropusher.
23. Similarly replace oil scraper caps of other valves.
24. Install a block head on the engine (see. "Replacement of laying of a head of the block of cylinders").
25. Oil engine support of camshafts in a head of the block and hydropushers.
26. Install camshafts in block head support so that cams of the 1st cylinder were directed from pushers of valves aside.

Note
The camshaft of inlet valves is supplied with a distinctive corbel.

27. Oil engine necks …
28. … and cams of camshafts.
29. Apply sealant like "Loktayt-574" on the surface of a head of the block of cylinders interfaced to the case of bearings of camshafts with roller with a diameter of 2 mm.

Prevention
It is allowed to launch the engine not earlier than in 1 h after putting sealant.

30. Install the case of bearings and tighten bolts of its fastening evenly cross-wise, since average support.

Note
The case of bearings is aligned by the plugs pressed in a head of the block of cylinders. Before installation of the case check their existence and correctness of a press fitting.

31. Establish the removed details of the gas-distributing mechanism (see. "Replacement of laying of a head of the block of cylinders") also adjust a tension of a belt of the drive of the gas-distributing mechanism (see. "Replacement of a belt of the drive of the gas-distributing mechanism and tension roller").
32. Establish the removed details of the drive of the generator and adjust a generator drive belt tension (see. "Check of a tension of a belt of the drive of the generator").
