3.2.1.11. A head of cylinders


The prevention

To facilitate assemblage, put labels on removed arms, and also to designate routes of packing of wires and hoses.


Removal

PERFORMANCE ORDER
1. Merge cooling liquid.
2. Remove cam-shafts (subsection 3.2.1.9 see).
3. Keep in mind that in the description resulted more low head removal in gathering with final and soaking up collectors is meant. Thus the amount of works on head removal decreases, but manipulations with a head because of the increased sizes and weight of all assemblage are at a loss. It is recommended to remove at first both collectors (subsection 6.1.12 and subsection 6.1.13 see).
4. On engines with preliminary preparation топливно – an air mix (single-channel system of injection) execute following actions:

  – cнимите the air filter;
  – Execute actions on декомпрессии fuel system and disconnect from the chamber throttle заслонки a hose of giving of fuel and a return hose (muffle all apertures to exclude losses of fuel and hit of a dirt in fuel system);
  – Disconnect a cable of a drive throttle заслонки;
  – Disconnect sockets of conducting from the chamber throttle заслонки, a soaking up collector and other details;
  – Disconnect hoses of the vacuum amplifier of brakes, systems of cooling and ventilation system картера from corresponding valves and the branch pipes mounted on a head of cylinders;
  – Remove a basic arm of a soaking up collector;
  – Disconnect from a final collector a reception pipe of the muffler.
5. On engines with direct injection of fuel (with multichannel system of injection) execute following actions:

  – Remove the air filter and an air line;
  – Execute actions on декомпрессии fuel system and disconnect from the distributor of fuel a hose of giving of fuel and a return hose (muffle all apertures to exclude losses of fuel and hit of a dirt in fuel system);
  – Disconnect a cable of a drive throttle заслонки;
  – Disconnect sockets of conducting from the chamber throttle заслонки, a soaking up collector and other details. Disconnect conducting from atomizers and take aside that did not disturb to removal of a head of cylinders;
  – Disconnect hoses of the vacuum amplifier of brakes, systems of cooling and ventilation system картера from corresponding valves and the branch pipes mounted on a head of cylinders;
  – Remove a basic arm () a soaking up collector;
  – Disconnect from a final collector a reception pipe of the muffler.
6. On the cars equipped with automatic transmission, disconnect a switching cable on a hill-climbing gear from the chamber throttle заслонки.
7. Ослабьте collars also disconnect hoses from the pump of a cooling liquid, from a radiator of a heater and from маслоохладителя (if it is provided). Disconnect also hoses of a radiator of system of cooling in a forward part of a head of cylinders.
8. On engines with direct injection of fuel of updating Phase I remove a starter (subsection 7.6) then ослабьте see and turn away a bolt of fastening of pipelines of a cooling liquid to a back part of the block of cylinders.
9. Disconnect sockets of conducting from the ignition distributor, from the coil of ignition and from a transistor power unit. Disconnect a sleeve of conducting from collars, take aside from a head of cylinders. Turn away bolts and remove all wires on the weight, fixed on a head of cylinders and on a soaking up collector.
10. Release bolts of fastening of an arm of the generator to a head of cylinders.
11. Ослабьте an inhaling also turn away bolts М6, крепящие a head of cylinders to a chain cover газораспределительного the mechanism (if these bolts are not turned on yet), turn on also a bolt in a forward part of a head of cylinders.
12. Working in sequence, return represented on the scheme, 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.
13. Get bolts and washers, having paid attention to their position in a head of cylinders.
14. Remove a head of cylinders. This operation is desirable for carrying out with the assistant, as a head in gathering with cam-shafts heavy enough (especially if collectors are not removed). Remove from the block of cylinders a lining, having paid attention to two adjusting pins. If pins get from apertures remove them, having remembered position of initial installation, and store with a head of cylinders. Will pay also attention to correct installation of oil atomizers in the block of cylinders. If atomizers are weakened also them it is possible to take out, remove them and store together with a head of cylinders.
15. 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.
16. If the head understands for major repairs be guided by the description in corresponding subsection.

Preparation for assemblage

PERFORMANCE ORDER
1. The manufacturer recommends to measure bolts of fastening of a head of cylinders for the purpose of definition of their further suitability. Measure length of each bolt (preliminary having removed washers) from an internal surface of a head of a bolt to an end face of a carving part. If length of all bolts less than 158,2 mm bolts can be used. If the length at least one of bolts exceeds 158,2 mm in the complete set it is necessary to replace all bolts. Taking into account those efforts which test bolts of a head of cylinders, insistently it is recommended to replace them irrespective of a condition.
2. Before installation of a head of cylinders on the engine carefully clear demountable surfaces of a head and the block. Remove the rests of a deposit and a lining material firm plastic or wooden шпателем, clear also of a deposit of the bottom of pistons. At clearing observe extra care as surfaces can be damaged easily. Also take the measures excluding hit of the deleted deposit in oil channels or channels of system of cooling in the block of cylinders, blocking of channels and infringement of greasing of details of the engine otherwise is possible. A sticky tape and a paper close apertures of oil channels, channels of system of cooling and an aperture under bolts in the block of cylinders. To exclude dirt hit in a backlash between the piston and the cylinder cover a backlash консистентной with greasing on edge of the bottom of the piston. After clearing of pistons remove a brush greasing from a backlash and wipe the rests of greasing pure rags.
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. If there are suspicions on deformation of demountable surfaces check up a deviation of these surfaces from a plane by means of calibre.

Installation

PERFORMANCE ORDER
1. Wipe dry demountable surfaces of a head and the block of cylinders. Put into place two adjusting pins (if acted in film) and insert oil atomizers into the block of cylinders.
2. Put on the block of cylinders a new lining, having combined apertures in a lining with pins.
3. With the assistant cautiously establish a head on the block of cylinders, having combined a head with adjusting pins.
4. Grease carvings and the bottom parts of heads of bolts with pure oil. Dress on bolts of a washer and cautiously insert bolts into corresponding apertures in a head of cylinders (to drop bolts in apertures it is not supposed). Wrap bolts and tighten by hand.
5. Tighten the basic 10 bolts of fastening of a head of cylinders in the specified sequence, with the moment corresponding to 1 stage of an inhaling. To tighten динамометрическим a key with a face head.
6. After performance of 1st stage of an inhaling tighten bolts with the moment of 2nd stage.
7. Wait minute and release bolts in sequence of return specified on the scheme of a tightening of bolts in item 5. Weaken an inhaling gradually, on 1/2 turns for reception, until then while bolts not begin to turn away by hand.
8. Again tighten 10 bolts by hand, then tighten, observing sequence, with the moment of 3rd stage of an inhaling.
9. After performance of 3rd stage, tighten bolts on a corner specified for 4th stage of an inhaling. The inhaling at the given stage is recommended to be carried out a key with an angular scale to provide exact performance of requirements to an inhaling. In the absence of a key with an angular scale put a label paint on a head of a bolt and on a surface of a head of cylinders. Labels should settle down under the set corner. On these labels it is necessary to be guided at performance of 4th stage of an inhaling.
10. After performance of 4th stage of an inhaling of the basic bolts of a head of cylinders tighten bolts with the moment of 5th stage, observing the specified sequence.
11. After a definitive inhaling of the basic bolts of a head of cylinders wrap bolts М6 in a forward part of a head of cylinders and tighten them with the set moment.
12. Lay conducting on a former route, connect conducting sockets to the ignition distributor, to the coil of ignition and to a transistor power unit. Fix conducting in a place обвязками and collars.
13. Attach to a head of cylinders and to a collector the wires going on weight, reliably tighten bolts.
14. On engines with direct injection of fuel of updating Phase I screw in the block of cylinders a bolt of fastening of a branch pipe of system of cooling and reliably tighten. Establish a starter (subsection 7.6 see).
15. Attach hoses of system of cooling, observing an initial order of their installation, fix hoses collars.
16. Being guided by a corresponding Part in Chapter 4, execute following operations:

  – Attach all conducting, hoses and management cables to details of fuel system and to a soaking up collector;
  – Establish a basic arm of a soaking up collector;
  – Attach a reception pipe of the muffler to a final collector;
  – Establish the air filter and the air line channel (if it is provided).
17. On the cars equipped with automatic transmission, attach and adjust a switching cable on a hill-climbing gear.
18. Establish cam-shafts (subsection 3.2.1.9 see).
