2.7.3. Removal and camshaft installation (on the established engine)The shaft can be removed and mounted on the engine established on the car. To perform this work it is necessary as follows:
- To turn a cranked shaft until any of pistons will not be in ВМТ;
- To disconnect the top part of a protective guard of a gear belt;
- To dismantle a cover of a head of the block of cylinders;
- To turn away a bolt of a pulley of a camshaft;
- To weaken a tension of a gear belt as it is described in the previous subsection;
- To dismantle a gear belt and to remove a gear pulley from a camshaft;
- To remove the ignition distributor (подразд. 7.2.5);

- Using fig. 32, slowly serially раскрепить on each party and to remove covers of bearings № 5, 1 and 3. To turn out both bolts 1 (fig. 86) from a cover of the forward bearing;
- To weaken in regular intervals, cross-wise nuts of covers of bearings № 2 and № 4 to an outright release of both covers. To remove covers and to take out a shaft. To examine covers. Wide бурт And (fig. 32 see ) is on the party of an admission of the engine. Cover number In should be read from outside engine release;
- If it is necessary, to take out pushers. Посколку it is impossible to interchange the position of pushers, they should be marked, is better to designate lines on an inside, for example, the first pusher is designated by one line, the second — two etc. At storage pushers to stack on planes of contact to cams that oil did not change the position. It is necessary to operate, since the drive party газораспределительного the mechanism.
At installation распределительно a shaft to execute the following:
- To grease necks of a camshaft with engine oil and to establish a shaft in bed of bearings;
- To take serially in hands of a cover of bearings and to establish, on what party is wide бурт And, specified in fig. 32. It is necessary on the party of an admission of the engine. To establish covers according to sequence of numbering. Numbers () should be clearly visible from outside a final collector;
- To check up, whether is any of pistons in ВМТ, and to tighten covers of bearings № 2 and № 4 serially, cross-wise the moment of an inhaling equal 6 Нм;
- To tighten covers of bearings № 3, 1 and 5 serially, cross-wise the moment equal 6 Нм;
- To tighten all nuts serially on 1/4 turns (90 );
- To establish and tighten both bolts 1 (fig. 86 see ) the moment 10 Нм;
- Again to establish приводной a belt as it is described above, and to perform other works in sequence, return to dismantle.
The note
If new hydropushers are established, do not start up the engine within approximately 30 minutes, otherwise pistons can hit about valves.
