2.1.5.2. Removal and installation of a head of the block of cylinders

GENERAL INFORMATION

Knot of a head of the block of cylinders of the engine 2,3 - I-VR5

.1-top part of an inlet collector. The top part inlet first of all fastens to the lower part of an inlet collector, and then the collector assembled fastens to a head of the block of cylinders;
2–throttle case;
3–bolt, 10 Nanometers;
4–cover;
5–cover of a head of the block of cylinders. At cover installation, on cover perimeter in segment dredging it is necessary to put a WV-D454300a3 hermetic layer;
6–arm;
7–bolt, 25 Nanometers;
8–bolt of fastening of a head of the block of cylinders. At installation it is necessary to use new bolts and a tightening of bolts to make in a certain sequence in some stages;
9–head of the block of cylinders. At not planeness more than 0,1 mm it is necessary to make repolishing of a head of the block of cylinders. Minimum admissible height of a head of the block of cylinders of 139,5 mm;
10-round sealing ring. At installation it is necessary to use the new sealing ring greased with pure engine oil;

11-cover of a driving chain. Removal and installation of a cover of a driving chain can be made only on the established head of the block of cylinders. At installation of a cover of a driving chain it is necessary to fill openings in a cover end face with liquid VW-AMV18800102 hermetic;
12-device of a tension of a chain, 40 Nanometers. The engine can be turned only with the established device of a tension of a chain;
13-sealing ring;
14-water pump;
15-block of system of ignition;
16-thermostat casing;
17-sealing ring. At violation of tightness it is necessary to use a new sealing ring;
18-laying of a head of the block of cylinders. At installation it is necessary to use new laying of a head of the block of cylinders;
19-lower part of an inlet collector;
20-consolidation for the top part of an inlet collector. At damage it is necessary to use new consolidation;
21-bolt, 5 Nanometers;
22-the combined valve;
23-consolidation for the lower part of an inlet collector. At damage it is necessary to use new consolidation;
24-mechanism of a tension of a maple belt;
25-bolt, 5 Nanometers;
26-arm;
27-vacuum executive mechanism

Sequence of a tightening of bolts of fastening of a head of the block of cylinders on the VR5 engine


Prevention

Operations on removal and installation of a head of the block of cylinders of the VR5 engine are similar to operations on removal and installation of a head of the block of cylinders on the four-cylinder petrol engine. In this section differences for removal and installation of a head of the block of cylinders on VR5 engines are stated only.


PERFORMANCE ORDER
1. Remove hinged elements from a head of the block of cylinders and a cover of a head of the block of cylinders.
2. Unscrewing of bolts of fastening of a head of the block of cylinders make in sequence, return to their tightening (see fig. Sequence of a tightening of bolts of fastening of a head of the block of cylinders on the VR5 engine).
3. Clear openings (are specified by shooters) in diameter of 3 mm of hermetic in an end face of a cover of driving chains.
4. Fill openings in an end face of a cover of a driving chain with liquid VW-AMV18800102 hermetic.

Prevention

After installation of a head of the block of cylinders of an opening for hermetic in an end face of a cover of a driving chain are half closed.


5. Before installation of laying of a head of the block of cylinders check that in openings 15 and 16 (see fig. Sequence of a tightening of bolts of fastening of a head of the block of cylinders on the VR5 engine) the block of cylinders directing plugs are established.
6. Being careful, establish a head on the block of cylinders. Insert and tighten manually bolts with washers of fastening of a head of the block of cylinders.
7. In a certain sequence (see fig. Sequence of a tightening of bolts of fastening of a head of the block of cylinders on the VR5 engine) tighten all bolts the moment of a tightening of 30 Nanometers, then tighten all bolts the moment of a tightening of 50 Nanometers and in summary in two steps tighten all bolts, each time on 90 °.
