Removal and installation

PERFORMANCE ORDER

Prevention

These details can be removed without dismantle of a head of cylinders. For this purpose the valve should be held compressed air or adaptation.


1. Uncover a head of cylinders.
2. Turn out a spark plug from that cylinder on which details of the valvate mechanism, or all candles will change.
3. Install the piston of the 1st cylinder in compression step VMT. If all oil scraper caps change, then begin replacement with the 1st cylinder and further change consistently, installing each cylinder in VMT according to an engine operating procedure.
4. Screw in an opening for a candle an adapter.
5. Remove the roller(s) and a yoke (a), get a pusher(s) bar(s).
6. Give to the cylinder which is in VMT, compressed air, holding the crankshaft with a key.
7. Valves have to nestle on saddles.
8. In the absence of compressed air enter a piece of a thick kapron rope into an opening before the piston reaches VMT. Then tighten the crankshaft to feeling of resistance to pulling of a rope.
9. Muffle rags all openings in a head of cylinders and squeeze a spring adaptation. Remove crackers.
10. Remove adaptation, a glass of a maslootrazhatel, a spring and a cap.

Prevention

If at this stage air leak (if it is applied) is found, then the head of cylinders should be removed for dismantling and repair.


11. Dump air pressure, having wound the valve with a tape, or slightly turn the crankshaft in the direction of normal rotation.
12. Check a condition of a core of the valve and its deformation, having turned the valve in the plug.
13. Check freedom of forward movement of the valve in the plug. If the valve jams, then either will bend the valve, or the plug is damaged. The head of cylinders in this case should be removed for dismantling and repair.
14. Again fix the valve (having given air or having pushed a rope piece).
15. Grease a core and dress a new cap.
16. Establish a spring (it has to be turned down by color marking (2)) and a glass (1 – up).
17. On final valves (2) the rotator (3) is installed, on cores of these valves there is one flute. On inlet valves (1) the plate (4) is established, on cores of these valves there are 2 flutes (engine 3F-E).
18. Establish crackers (the drawing at the left, 1 – a cracker of the inlet valve, 2 – a cracker of the final valve), having recorded them lubricant (a photo on the right).
19. Remove adaptation establish all removed details upside-down.
20. Start the engine, be convinced of lack of a leak and listen to operation of the valvate mechanism.
