3.11.2. Removal and installation on the car

Head of cylinders remove from the engine on the car if for malfunction elimination it is not necessary to remove the engine or if it is necessary to remove only a deposit from a surface of the chamber of combustion and valves.

Removal

PERFORMANCE ORDER
1. Merge cooling liquid from a radiator and the block of cylinders and remove the air filter.
2. Disconnect wires from the storage battery, spark plugs and from the gauge of the index of temperature of a cooling liquid.
3. Disconnect a cable of a drive air заслонки from the carburettor.
4. A key 67.7812.9514 turn out spark plugs and the gauge of temperature of a cooling liquid.
5. Disconnect draughts of a drive throttle заслонки from the intermediate lever on a cover of a head of cylinders and uncover.
6. Turn a cranked shaft before label combination on a pulley with a long label on a cover of a drive of a camshaft (fig. the Arrangement of labels for ignition installation see), and labels on an asterisk of a camshaft with a label on the case of bearings of a camshaft (Check of coincidence of an adjusting label fig. see an asterisk of a camshaft with a label on the case of bearings).
7. Disconnect a hose from a tube of a supply of a liquid to a heater, and from a final collector – an arm of fastening of a tube of tap of a liquid from a heater.
8. Disconnect hoses from the carburettor, the inlet pipeline and from a final branch pipe of a cooling shirt of a head of cylinders.
9. Disconnect from a final collector a protective guard of a starter and a reception pipe of mufflers.

The prevention

The final collector and the inlet pipeline with the carburettor is better for leaving on a head. They can be removed later at dismantling of a head of cylinders.


10. Release колпачковую a nut натяжителя chains, wring out an assembly shovel a rod натяжителя and fix it колпачковой a nut.
11. Remove an asterisk of a camshaft and the case of bearings together with a camshaft.
12. Turn away bolts of fastening of a head of cylinders to the block and remove a head.

Installation

PERFORMANCE ORDER
1. Again to establish and fix a head on the block of cylinders, perform the described operations in return sequence, thus:
      – Do not forget to put a lining of a head of cylinders and a lining of a cover of a head;
      – Tighten bolts of fastening of a head in the sequence specified in rice the Order of a tightening of bolts of a head of cylinders, and nuts of hairpins of the case of bearings of a camshaft – in the sequence specified in fig. the Order of a tightening of nuts of the case of bearings of a camshaft.
2. Bolts of fastening of a head of cylinders tighten in two steps:
      – Preliminary the moment 33,3–41,16 Н·м (3,4–4,2 кгс·м) bolts 1–10;
      – Definitively moment 95,94–118,38 Н·м (9,79–12,08 кгс·м) bolts 1–10 and the moment 31,36–39,1 Н·м (3,2–3,99 кгс·м) a bolt 11.
3. At installation of a chain pay attention to coincidence of adjusting labels (Check of coincidence of an adjusting label fig. see an asterisk of a camshaft with a label on the case of bearings and fig. &nbspррёяюыюцхэшх labels for ignition installation). Pull a chain as it is specified in subsection 3.12.3.
4. At installation of a cover of a head of cylinders with a lining, nuts of fastening of a cover tighten the moment no more than 7,85 Н·м (0,8 кгс·м) not to cause lining rupture on fixing apertures and коробление a cover. At repair of the engine it is recommended to replace a cover lining new.
5. After installation of a head of cylinders check up and adjust the ignition moment.
