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

THE GENERAL DATA

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

1 – the top part of an inlet collector. The top part inlet first of all fastens to the bottom part of an inlet collector, and then the collector  in gathering fastens to a head of the block of cylinders; 2 – the throttle case; 3 – a bolt, 10 Nanometers; 4 – a cover; 5 – a cover of a head of the block of cylinders; 6 – an arm; 7 – a bolt of fastening of a head of the block of cylinders. At installation it is necessary to use new bolts; 8 – a head of the block of cylinders. At неплоскостности more than 0,1 mm  it is necessary to make repolishing of a head of the block of cylinders. Is minimum admissible height of a head of the block of cylinders of 139,5 mm; 9 – a sealing ring. At  installation it is necessary to use the new sealing ring    greased with pure engine oil; 10 – a sealing ring; 11 – the Hall gauge;

12 – the 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 – the water pump; 14 – a sealing ring. At tightness infringement it is necessary to use a new sealing ring; 15 – the block of system of ignition; 16 – a bolt, 25 Nanometers; 17 – a cover приводной chains. Removal and cover installation приводной can be made chains only on the established head of the block of cylinders. At cover installation приводной it is necessary for chain to fill apertures in a cover end face with liquid hermetic VW-AMV18800102; 18 – a thermostat casing; 19 – a lining of a head of the block of cylinders. At installation it is necessary to use a new lining of a head of the block of cylinders; 20 – the bottom part of an inlet collector; 21 – linings of the bottom part of an inlet collector; 22 – the valve for switching of channels of an inlet collector; 23 – the vacuum executive mechanism

Arrangement of apertures for hermetic in a cover приводной chains


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


Operations on removal and installation of a head of the block of cylinders of engine VR5 are similar to operations on removal and installation of a head of the block of cylinders on the four-cylinder petrol engine. In this subsection differences for removal and installation of a head of the block of cylinders on engines VR5 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, to return their tightening, Sequence of a tightening of bolts of fastening of a head of the block of cylinders fig. see engine VR5. 3. Clear apertures in diameter of 3 mm of hermetic in a cover end face приводных chains, fig. the Arrangement of apertures for hermetic in a cover приводной chains see. 4. Fill apertures in a cover end face приводной chains with liquid hermetic VW-AMV18800102. The prevention After installation of a head of the block of cylinders of an aperture for hermetic in a cover end face приводной chains are half closed. 5. Before installation of a lining of a head of the block of cylinders check up that in apertures 15 and 16 blocks of cylinders it is established directing plugs, Sequence of a tightening of bolts of fastening of a head of the block of cylinders fig. see engine VR5. 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 certain sequence (Sequence of a tightening of bolts of fastening of a head of the block of cylinders fig. see engine VR5) 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 .
