2.4.4.2. Removal of shaft of inlet and final valves

As the axial gap of the camshaft is very small, for prevention of jamming and/or damage of a shaft at its dismantle it is necessary to hold a shaft in horizontal position, for this purpose it is necessary to observe the procedure of dismantle stated below.

Fig. 2.249. Adjusting tags on the leader and conducted gear wheels of camshafts: 1 – tags


For removal of a shaft of inlet valves of a back head of the block of cylinders combine adjusting tags on the leader and conducted gear wheels of camshafts, as shown in the figure 2.249.

Fig. 2.250. Fastening of an auxiliary gear wheel: 1 – main gear wheel; 2 – auxiliary gear wheel; 3 – technological bolt


Attach an auxiliary gear wheel of the camshaft of final valves to the main gear wheel a technological bolt (fig. 2.250).
The recommended technological bolt:
diameter of a carving – 6 mm;
carving step – 1,0 mm;
bolt length – 16–20 mm.
Before removal of the camshaft of inlet valves be convinced of reliable fixing of an auxiliary gear wheel by a technological bolt.

Fig. 2.251. Order of weakening of bolts of fastening of covers of bearings of inlet valves of a back head of the block of cylinders


Evenly weaken and remove ten bolts of fastening of covers of bearings in several passes, in the sequence specified in the figure 2.251.
Remove five covers of bearings and the camshaft.

Fig. 2.252. Order of weakening of bolts of fastening of covers of bearings of final valves of a back head of the block of cylinders


For removal of a shaft of final valves of a back head of the block of cylinders evenly weaken and remove ten bolts of fastening of covers of bearings in several passes, in the sequence specified in the figure 2.252.
Remove five covers of bearings, an epiploon and the camshaft.

Fig. 2.253. Adjusting tags on the leader and conducted gear wheels of camshafts: 1 – tags


For removal of a shaft of inlet valves of a forward head of the block of cylinders combine adjusting tags on the leader and conducted gear wheels of camshafts.


Fig. 2.254. Fastening of an auxiliary gear wheel: 1 – main gear wheel; 2 – auxiliary gear wheel; 3 – technological bolt


Attach an auxiliary gear wheel of the camshaft of final valves to the main gear wheel a technological bolt (fig. 2.254).
The recommended technological bolt:
diameter of a carving – 6 mm;
carving step – 1,0 mm;
bolt length – 16–20 mm.
Before removal of the camshaft of inlet valves be convinced of reliable fixing of an auxiliary gear wheel by a technological bolt.

Fig. 2.255. Order of weakening of bolts of fastening of covers of bearings of inlet valves of a back head of the block of cylinders


Evenly weaken and remove ten bolts of fastening of covers of bearings in several passes, in the sequence specified in the figure 2.255.
Remove five covers of bearings and the camshaft.

Fig. 2.256. Order of weakening of bolts of fastening of covers of bearings of final valves of a back head of the block of cylinders


For removal of a shaft of final valves of a back head of the block of cylinders evenly weaken and remove ten bolts of fastening of covers of bearings in several passes, in the sequence specified in the figure 2.256.
Remove five covers of bearings, an epiploon and the camshaft.
