Removal and installation of heads of cylinders

REMOVAL

 PERFORMANCE ORDER

1. Take off a V-shaped belt (see the Head Routine maintenance).
2. Remove a pulley of a cranked shaft (see the Section Removal and installation of a pulley of a cranked shaft).
3. Uncover the GRM driving belt (see the Section Removal and installation of forward covers of the GRM drive).
4. Remove assembly of a belt of the GRM drive (see the Section Removal and installation of a belt of the GRM drive, check of a condition of components).
5. Remove a camshaft cogwheel (see the Section Removal, check of a state and installation of cogwheels of camshafts).
6. Disconnect the inlet pipeline (see the Head of the Power supply system and release).
7. Turn out bolts of fastening of an arm of the K/V compressor to a head of cylinders.
8. Remove assembly of yokes (see the Section Removal, check of a state and installation of elements of the drive of valves).
9. Remove a camshaft (see the Section Removal and installation of camshafts).

10. Working in strictly certain order, turn out 6 bolts bolts of fastening of a head of cylinders.

 Bolts (1) and (2) leave wrapped up on three-four rounds for the purpose of fixing of a head at the last stage.

11. Having tapped a head on perimeter a hammer with soft brisk, separate it from the block of cylinders.
12. Finally turn out the remained bolts and remove a head.
13. Remove sealing laying of a head of cylinders.

 Try not to scratch the interfaced surfaces of a head and the block!

14. Working in a similar manner, remove the right head of cylinders.

Preparation for installation

 PERFORMANCE ORDER

1. Carefully smooth out and wipe dry the interfaced surfaces of a head and the block of cylinders. For removal of all traces of material of old laying and a deposit use a firm plastic or wooden scraper. Also clear the bottoms of pistons. Be extremely careful, - it is easy for surface to damage. Remember that dirt should not get to maslotok, water galleries, channels and carving openings - a zakuporta their traffic jams or stick with an adhesive tape. For prevention of hit of a deposit in gaps between pistons and cylinders, fill the last of dense greasing which upon completion of procedure of cleaning will be easy to be removed with a rigid brush. Upon completion of cleaning wipe all surfaces pure dry rags.
2. Survey the interfaced surfaces of a head and the block on existence of deep scratches, cracks and other damages. Small defects can be eliminated with a small shaber, in more serious cases the head should be pierced, or to replace.
3. Make sure of purity and dryness of carving openings, - just in case blow them compressed air (it is possible to use the bicycle pump). Presence at deaf openings of traces of greasing can lead to destruction of the block at a tightening of bolts as a result of increase of hydraulic pressure.
4. By means of a steel ruler and the probe of lezviyny type check planeness of the interfaced head surface (see the Section Service of a Head of cylinders of the present Chapter).

INSTALLATION

 PERFORMANCE ORDER

1. Having replaced sealing laying, establish a head of cylinders on the regular place on the block.
2. Motive oil carving parts of fixing bolts, persistent surfaces of their heads and a washer.

3. Screw bolts and tighten them in strictly certain order, with effort of 29 Nanometers, then, in the same order hold on with effort of the second stage (69 Nanometers).

4. In two steps release bolts, turning everyone on 180 ° for approach.
5. Tighten bolts (1) and (2) with effort of 34 Nanometers, then tighten bolts (3), (4), (5) and (6) with effort of 15 Nanometers. Further hold on all bolts in ascending order of serial numbers 80 ÷ 90 (no more) than degrees.

6. At the final stage it is necessary to hold on bolts for 80 ÷ 90 degrees in the order specified illustrations.

 The total corner of a dotyagivaniye of bolts at the last two stages should not exceed 180 °!


7. Further installation is made as it should be, the return to an order of dismantle of components.
