Fig. 2.124. Installation of the valve in a head of the block of cylinders

Insert the valve into a head of the block of cylinders (fig. 2.124).

Put on adaptation tip (Mot. 1511) on a valve core (internal diameter of a tip has to be equal to diameter of a core).

Fig. 2.125. Keeping of the valve in a saddle

Hold the valve pressed to a saddle (fig. 2.125).

Establish the maslootrazhatelny cap which is (not oiled) on a tip.

Fig. 2.126. Installation of a maslootrazhatelny cap

Advance a maslootrazhatelny cap before its transition through a tip (fig. 2.126).

Fig. 2.127. Removal of a tip of adaptation

Remove a tip (fig. 2.127).

Fig. 2.128. Installation of a mandrel on a maslootrazhatelny cap

Establish a mandrel on a maslootrazhatelny cap (fig. 2.128).

NOTE Internal diameter of a mandrel has to coincide with diameter of a core of the valve. Besides, the lower part of a mandrel has to rest against a maslootrazhatelny cap which serves as a basic washer of a spring of the valve partially.

Fig. 2.129. Napressovka of a maslootrazhatelny cap

Napressuyte a maslootrazhatelny cap, having knocked with a palm by the top part of a mandrel until the maslootrazhatelny cap adjoins to a head of the block of cylinders (fig. 2.129).

Repeat the operations stated above for all valves.

Fig. 2.130. Installation of a valvate spring

Establish springs and plates of springs (fig. 2.130).

Fig. 2.131. Installation of crackers

Insert crackers by means of curved nippers (fig. 2.131).

Install the thermostat block with new laying on a head of the block of cylinders.

Fig. 2.132. Order of tightening of bolts of fastening of the case of the thermostat

Tighten in the order shown in the figure 2.132 the required moment (10 N · l) bolts of fastening of the block of the thermostat on a head of the block of cylinders.

Establish a final collector with new laying.

Fig. 2.133. Order of tightening of nuts of hairpins of fastening of a final collector

Tighten in the order specified in the figure 2.133 the required moment (23 N · l) nuts of hairpins of fastening of a final collector.

Install the heat-shielding screen of a final collector.

Tighten the required moment (1 N · l) bolts of fastening of the heat-shielding screen of a final collector.

ATTENTION Make sure that the heat-shielding screen of a final collector is reliably fixed between the oxygen sensor and a collector (to avoid an overheat which can cause destruction of an electrical wiring of the top oxygen sensor).

Tighten the required moment (4,5 N · l) the oxygen sensor by means of adaptation (Mot. 1495).

Establish a pro-rate of an internal casing of the GRM drive.

Establish linings of cases of nozzles with new laying.

Install the oxygen sensor.

Fig. 2.134. Alignment of laying of cases of nozzles

Level a lining of cases of nozzles in relation to a head of the block of cylinders (from the GRM drive) (fig. 2.134).

Level the planes of interface of a lining of cases of nozzles in relation to a head of the block of cylinders.

Fig. 2.135. Order of tightening of bolts of fastening of a lining of cases of nozzles

Tighten in that order the required moment (21 N · l) bolts of fastening of a lining of cases of nozzles (fig. 2.135).
