3.1.2.1.12. Dismantling, repair and assemblage of a head of the block of cylinders Dismantling

PERFORMANCE ORDER

1. To arrange a head of the block of cylinders in forward and back parts on two wooden брусках. 2. To remove an inlet collector together with the carburettor, and also a final collector. 3. To remove the distributor and the fuel pump. 4. To uncover the camshaft bearing from outside a flywheel. 5. To remove a pulley of a drive of a camshaft, holding with its special core serving for installation timing. 6. To remove a plastic casing and маслопровод. 7. To remove five covers of bearings of a camshaft, and then to take a camshaft. 8. By means of a special sucker to take pushers. To designate pushers, and also adjusting plates. 9. Using the standard adaptation, to compress a valve spring. 10. To take valve crackers. 11. To remove the adaptation for compression of springs and to remove the top plate of a spring. 12. To take клапанную a spring. 13. To take the bottom plate of a spring of the valve. 14. From a head underside to take the valve. Valves act in film one after another, since the drive party газораспределительного the mechanism. Valves are necessary for marking a sticky tape or to spread out so that at assemblage they have risen on the places. 15. To remove маслоотражательные caps. 16. To take from the oil channel the additional oil filter. 17. To clear surfaces of connection of a head of the block of cylinders (it is necessary to use means Magnus Magstrip or Framet Decaploc). 18. To clear and carefully to blow compressed air all details. The prevention It is impossible to use adaptations which can scratch cleared details. 19. By means of a ruler and щупа to check up planeness of the bottom surface of connection of a head of the block of cylinders. Maximum неплоскостность makes 0,05 mm. The manufacturer does not suppose grinding of the bottom surface of connection of a head of the block of cylinders at service repairs.

Replacement of directing valves

In case of detection of too big backlash of valves in the directing it is necessary to replace the directing. This operation is necessary for entrusting a specialised car repair shop.

---

The prevention

At replacement directing the valve repolishing of a saddle of the valve corresponding to it is obligatory.

---

Grinding in of valves

Grinding in of valves is necessary for making with application only fine-grained polishing paste.

PERFORMANCE ORDER

1. A surface of a saddle of the valve to grease with a small amount of paste and to establish the valve in a corresponding saddle. Densely to press to a valve plate a rubber sucker and to rotate the valve in one or other party. 2. After the termination of process of grinding in all details carefully to clear of a dirt and paste and to check up a saddle and a valve plate. The continuous matte ring on both details which specifies width of a facet of the valve should be visible. 3. To put on a ring of a plate of the valve strokes a pencil on distance about 1 mm in regular intervals on a circle, then to insert the valve into directing plug and to turn it on 90 °, slightly thus pressing the valve. 4. To get the valve and to check up presence of strokes. If all strokes are erased, the valve can be finalised. Otherwise it is necessary to repeat grinding in operation. 5. To check up width прилегания valve plates. 6. To check up tightness прилегания. 7. After grinding and grinding in of valves it is necessary to clear a head of the block of cylinders carefully.

Assemblage of a head of the block of cylinders

Installation маслоотражательного a cap on a valve core

PERFORMANCE ORDER

1. To execute actions in return sequence in relation to dismantling process. 2. For each valve to execute actions in a following order:       – To arrange the valve in directing, observing corresponding position;       – To establish on a valve core new маслоотражательный a cap;       – To establish the bottom plate, a spring and the top plate;       – The special adaptation to compress a spring of the valve and to insert crackers. 3. To remove the adaptation for compression of springs. 4. To establish pushers on their former places (as before dismantling) together with corresponding adjusting plates. 5. To establish a camshaft, to fix covers of bearings and a lateral flange of a camshaft, to tighten covers of bearings the moment of 15 Nanometers. 6. To establish bearing consolidation from outside timing (the adaptation 7.0153). 7. To establish a pulley. 8. To check up and adjust a backlash of valves. Final actions on assemblage of a head of the block of cylinders to execute in return sequence in relation to dismantling process, i.e. to establish маслопровод, a bearing cover from outside a flywheel, the fuel pump, the distributor, inlet and final collectors (it is necessary to replace linings). 9. To establish gauges of temperature of a cooling liquid (if they have been removed). 10. To establish in an oil highway of a head the additional oil filter. 11. A special core to fix a camshaft pulley in installation position timing.
