3.1.1.11. A head of the block of cylinders

Sequence of an inhaling of bolts of a head of cylinders

Removal

PERFORMANCE ORDER
1. Disconnect the battery from weight.
2. Remove chains.
3. Remove both cam-shafts.
4. To facilitate head dismantle it is recommended to remove both collectors (subsection 6.1.12 and subsection 6.1.13 see).
5. Disconnect a reception pipe of the muffler from a collector.
6. Remove the air filter (subsection 6.1.2 see).
7. On carburettor engines will perform following works:

  – Disconnect from the fuel pump fuel hoses;
  – Disconnect a cable of a drive throttle заслонки;
  – Disconnect sockets of conducting from the carburettor;
  – Disconnect hoses of the vacuum amplifier of brakes, cooling systems, отсоса inside картерных gases and other hoses from corresponding valves and branch pipes of a head of cylinders;
  – Remove a rack of a soaking up collector;
  – On cars equipped каталитическим neutralizer disconnect a socket from the oxygen gauge.
8. On инжекторных engines will perform following works:

  – Execute actions on декомпрессии fuel system and disconnect from the fuel distributor fuel hoses;
  – Disconnect a cable of a drive throttle заслонки;
  – Disconnect sockets of conducting from the chamber throttle заслонки, a soaking up collector and other details and units;
  – Disconnect hoses of the vacuum amplifier of brakes, cooling systems, отсоса inside картерных gases and other hoses from corresponding valves and branch pipes of a head of cylinders;
  – Remove a collector rack;
  – On cars equipped каталитическим neutralizer disconnect a socket from the gauge of the fulfilled gases.
9. Disconnect from a head of cylinders hoses of system of cooling.
10. Turn out bolt М6, in a forward left corner of a head of cylinders.
11. Working in sequence, return represented on fig. Sequence of an inhaling of bolts of a head of cylinders, ослабьте an inhaling of all ten basic bolts of fastening of a head of cylinders. Weaken bolts in stages, on 1/2 turns for reception, until then while bolts not begin to turn away by hand.
12. Get bolts and washers, having paid attention to their orientation.
13. Working together, remove a head of cylinders, a lining, adjusting pins and an oil atomizer (if landing of pins and an atomizer ослабла).
14. If the head understands for major repairs be guided by the description in section 3.1.2.6.

Preparation for assemblage

PERFORMANCE ORDER
1. Check up a condition of carvings of bolts of fastening of a head of cylinders, irrespective of the reason of removal of a head. Bolts are recommended to be changed at each removal of a head of cylinders.
2. Clear demountable surfaces of a head and the block, having closed all apertures to exclude dirt hit. Backlashes in pistons cover with greasing which then remove.
3. Check up presence of damages on demountable surfaces of a head and the block of cylinders (deep scratches, having chopped off, etc.). Insignificant damages leave надфилем, serious damages leave only polishing.
4. Check up deformation of demountable surfaces of a head and the block.

Installation

PERFORMANCE ORDER
1. Wipe dry demountable surfaces of a head and the block of cylinders. Be convinced available directing pins on both parties of a plane of the block of cylinders and insert an oil atomizer into the block centre.
2. Put on the block of cylinders a new lining, having combined apertures in a lining with pins and an oil atomizer.
3. With the assistant cautiously establish a head on the block of cylinders, having combined a head with directing pins.
4. Grease carvings and the bottom parts of heads of bolts with pure oil.
5. Dress on washer bolts so that the conic surface of washers has been turned from a bolt head.
6. Cautiously insert bolts into corresponding apertures in a head (bolts not to drop), tighten them by hand.
7. Tighten bolts of 1-10 heads of cylinders in the specified sequence (fig. Sequence of an inhaling of bolts of a head of cylinders see) with the moment of 1st stage of an inhaling. Bolts 11–15 with carving М6 yet do not tighten.
8. Tighten bolts with the moment of 2nd stage.
9. After a minute also release bolts in sequence of return specified in fig. Sequence of an inhaling of bolts of a head of cylinders. Weaken an inhaling gradually, on 1/2 turns for reception, until then while bolts not begin to turn away by hand.
10. Observing sequence, tighten bolts with the moment of 3rd stage of an inhaling.
11. Tighten bolts on a corner of 4th stage of an inhaling or tighten динамометрическим a key with the moment of 4th stage.
12. Observing sequence, tighten bolts М6 (bolts 11–15) with the set moment.
13. Attach hoses of system of cooling.
14. Execute following operations:

  – Attach acting in film conducting, hoses and cables on a soaking up collector;
  – Attach a cable throttle заслонки;
  – Attach a reception pipe of the muffler, a socket of the gauge of the fulfilled gases (if it is provided);
  – Establish the air filter and an air line.
15. Establish cam-shafts (subsection 3.1.1.10 see).
16. Establish chains and asterisks.

The prevention

If major repairs of a head of cylinders before installation of a cover of a head of cylinders check up backlashes in valves on the cold engine (see subsection 3.1.1.9) are executed.


17. Start the engine and warm up. Check up backlashes in valves on the heated-up engine (subsection 3.1.1.9 see).
