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 performed 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, then 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 oil from the engine and remove an oil filter (see subsection 2.5.2).
4. Remove the camera of a butterfly valve, a nozzle and the distributor of fuel (see subsection 5.12).
5. Remove the 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 collectors can be removed together with a head of cylinders for final dismantling at the stand.
7. Remove the conducted cam-shaft gear wheel (see subsection 3.1.1.8) and a gear belt (see subsection 3.1.1.6).
8. Remove cam-shafts and pushers (cm. subsection 3.1.1.9, subsection 3.1.1.10).
9. Remove the generator and the distributor of ignition (see subsection 3.3.6 and subsection 3.3.11).
10. Put tags and remove other details (fastenings of pipes of the cooling system, cables, hoses and conducting).
11. Put tags and remove other details (fastenings of pipes of the cooling system, cables, hoses and conducting).
12. Disconnect cooling system branch pipes from a head of cylinders. 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 key with a six-sided head and the extender release bolts of a head of cylinders, turning off each bolt on 1/4 turns at one time. Release bolts in the sequence, return specified for an inhaling (see rice. Sequence of an inhaling of bolts of a head of the block of cylinders (engines of 1,3 l) and rice. 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, then very carefully hook a head from transmission for inflow, it is not allowed to separate a head in other places.
15. Remove other details from a head 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. Scrape off a deposit and the remains of material of laying. Demountable surfaces of a head and the block of cylinders have to 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, then laying of a head will not condense the place of a joint of a head and the block and at operation oil leaks will begin to develop. When working on the block of cylinders to a natolkayta in cylinders of pure rags to prevent hit of firm particles when cleaning. Remove the dirt which got to cylinders 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 of zadir, chips, hollows and other damages. Insignificant damages can be eliminated with a file, in the presence of serious damages the head or the block are subject to regrinding.
5. Close an adhesive tape carving openings in a head of cylinders and blow compressed air all channels and openings. Be convinced of purity of openings. During the work with compressed air put on 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 the damaged strings of a carving complicate a wraparound of a bolt and can be the reason of wrong indications of the moment at an inhaling.
7. Establish into place all details removed when dismantling a head.
8. Put new laying on the block of cylinders, focusing on pins. Pay attention to a tag of "UP" ("top") on laying.
9. Carefully put a head on the block of cylinders, without violating 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. Wrap short bolts on the party of inlet valves, and long - from final. Tighten bolts with the set moment in the specified sequence (see rice. Sequence of an inhaling of bolts of a head of the block of cylinders (engines of 1,3 l) and rice. 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 tighten bolts of a head of cylinders 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 the 2 and 3 inhaling stages bolts dovorachivatsya on 1/4 turns (90 °). At absence on your dynamometer key of an angular scale it is possible to apply 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 has to 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, then before installation into place grease a cap with sealant like RTV.
13. Before installation of a cover of a head of the block of cylinders check and if necessary adjust gaps in the mechanism of the drive of valves (see subsection 2.1).
14. After completion of works fill the cooling system with liquid and restore oil level in the engine (see subsection 2.3).
15. Start the engine, check whether there are leaks. Determine the ignition moment (see subsection 3.3.7) and carry out test of road performance of the car, having made a trip.
