3.1.1.11. Head of the block of cylinders

GENERAL INFORMATION

Sequence of an inhaling of bolts of a head of the block of cylinders (engines of 1,3 l)


Sequence of an inhaling of bolts of a head of the block of cylinders (engines of 1,6 l and 1,8 l)


Prevention

Works are carried out on the cold engine.


Removal

PERFORMANCE ORDER
1. Disconnect the battery from weight.

Prevention

If the stereoradio tape recorder of the car is equipped with security system, before a battery detachment from weight be convinced that you know an activation code.


2. Merge cooling liquid and turn out candles (see subsection 2.8.2).
3. Merge from the engine oil and remove the oil filter (see subsection 2.5.2).
4. Remove the chamber of a butterfly valve, a nozzle and the fuel distributor (see subsection 5.12).
5. Remove soaking-up collector (see subsection 3.1.1.4).
6. Remove a final collector (see subsection 3.1.1.5).

Prevention

The soaking-up collector and final can be removed collectors together with a head of cylinders for final dismantling at the stand.


7. Remove a conducted gear wheel of a cam-shaft (see subsection 3.1.1.8) and a gear belt (see subsection 3.1.1.6).
8. Remove cam-shafts and pushers (cм. subsection 3.1.1.9, subsection 3.1.1.10).
9. Remove the generator and the ignition distributor (see subsection 3.3.6 and subsection 3.3.11).
10. Put labels and remove other details (fastenings of pipes of system of cooling, cables, hoses and conducting).
11. Put labels and remove other details (fastenings of pipes of system of cooling, cables, hoses and conducting).
12. Disconnect from a head of cylinders branch pipes of system of cooling. After performance of this operation it is possible to start a final stage of removal of a head of cylinders.
13. By means of a natural a six-sided head and the extension piece release bolts of a head of cylinders, turning on each bolt on 1/4 turns at one time. Release bolts in sequence, return specified for an inhaling (see fig. Sequence of an inhaling of bolts of a head of the block of cylinders (engines of 1,3 l) and fig. The sequence of an inhaling of bolts of a head of the block of cylinders (engines of 1,6 l and 1,8 l)) to avoid deformation and cracks in a head of cylinders.
14. Remove a head of cylinders. If the head does not give in to removal, very carefully hook a head from transmission for inflow, it is not allowed to separate a head in other places.
15. Remove from a head other details that is necessary for survey and careful cleaning. Operations on repair of a head of cylinders are described in subsection 3.1.2.7).

Installation

PERFORMANCE ORDER
1. Before installation carefully clear demountable surfaces of a head and the block of cylinders.
2. To Soskrebita deposit and remains of a material of laying. Demountable surfaces of a head and the block of cylinders should be absolutely pure to provide reliable consolidation.
3. Wash out a demountable surface of a head of cylinders solvent of varnishes or acetone. If on the plane of the block of cylinders oil traces remained, laying of a head will not condense a place of a joint of a head and the block and at operation oil leaks will start to develop. At works on the block of cylinders натолкайте in cylinders of pure rags to prevent hit of firm particles when cleaning. The dirt which has got to cylinders, remove with the vacuum cleaner or by means of other suitable device.
4. Check existence on the demountable planes of a head and the block of cylinders задиров, chips, hollows and other damages. It is possible to eliminate insignificant damages with a file, in the presence of serious damages the head or the block are subject to repolishing.
5. Close a sticky tape carving openings in a head of cylinders and blow the compressed air all channels and openings. Be convinced of purity of openings. At work with the compressed air dress goggles.
6. Banish a carving of each bolt a die, having clamped a bolt in a vice to remove corrosion and to restore the damaged carving. Dirt, a rust, the remains of consolidation and damaged strings of a carving complicate a wraparound of a bolt and can be at the bottom of erroneous indications of the moment at an inhaling.
7. Establish into place all details which have been removed at dismantling of a head.
8. Put on the block of cylinders new laying, focusing on pins. Pay attention to a label "UP" ("top") on laying.
9. Carefully put a head on the block of cylinders, without breaking the provision of laying.
10. Before a wraparound of bolts oil persistent surfaces of heads of bolts for the engine.
11. Wrap by hand bolts of a head of cylinders on their former places. Short bolts wrap on the party of inlet valves, and long - from final. Tighten bolts with the set moment in the specified sequence (see fig. Sequence of an inhaling of bolts of a head of the block of cylinders (engines of 1,3 l) and fig. Sequence of an inhaling of bolts of a head of the block of cylinders (engines of 1,6 l and 1,8 l)). On engines of 1,3 l bolts of a head of cylinders tighten in two steps, and on l engines 1,6 and 1,8 – in three steps. Value of the moment of an inhaling is specified in in subsection 3.1.1.1). On 2 and the 3rd stages of an inhaling bolts доворачиваются on 1/4 turns (90 °). At absence on your dinamometrichesky key of an angular scale it is possible to put with paint risks on a head of each bolt and to tighten so that risk turned on 90°от initial situation (stage 2). On engines of 1,6 l and 1,8 l tighten bolts for 90 °, i.e. each bolt should turn concerning the 1st stage of an inhaling on 180 °.
12. Other operations on assembly are carried out upside-down.

Prevention

If when dismantling the semicircular cap of a cam-shaft of inlet valves on a head of cylinders was removed, before installation into place grease a cap with RTV type hermetic.


13. Before installation of a cover of a head of the block of cylinders check and if necessary adjust gaps in the mechanism of a drive of valves (see subsection 2.1).
14. After the completion of works fill system of cooling with liquid and restore oil level in the engine (see subsection 2.3).
15. Start the engine, check, whether there are leaks. Establish the ignition moment (see subsection 3.3.7) and carry out test of road performance of the car, having made a trip.
