3.3.8. Natyazhitel of a belt, asterisks and intermediate pulleys
ASTERISKS OF CAMSHAFTS
Asterisk of the camshaft of the right head of cylinders
|
|
The adjusting pin of a shaft of final valves has to enter a cut 1, and a pin of a shaft of inlet valves – a cut 2. |
Asterisk of the camshaft of the left head of cylinders
|
|
The adjusting pin of a shaft of final valves has to enter a cut 4, and a pin of a shaft of inlet valves – a cut 3. |
Removal
| PERFORMANCE ORDER |
| 1. Take off a gas-distributing belt. Turn a bent shaft approximately on 60 ° back. Thus, the probability of contact of valves with pistons decreases. |
|
2. Stop a camshaft asterisk by means of the self-made tool. |
|
3. Stop the camshaft of the removed asterisk by means of a wrench. |
|
4. Unscrew an asterisk bolt. |
|
5. Remove an asterisk. |
| 6. In the similar way remove other asterisks. |
|
Installation
| PERFORMANCE ORDER |
| 1. Check and, if necessary, replace epiploons of camshafts. |
| 2. Asterisks of camshafts of the right head of cylinders have marking 1 and 2, and asterisks of camshafts of the left head of cylinders – marking 3 and 4 (see rice. Asterisk of the camshaft of the right head of cylinders and rice. Asterisk of the camshaft of the left head of cylinders). Asterisks of both shaft on each head are identical. On each asterisk there are two tags. The table on use of these tags is given below. |
|
3. Establish asterisks. Adjusting pins have to be inserted into the corresponding cuts (are specified by shooters). |
|
4. Insert bolts. The corresponding synchronizing tags have to be combined with cuts in a cover (are specified by shooters). |
|
5. Tighten bolts till the necessary moment of an inhaling. |
|
6. Hold on bolts on a necessary corner. |
| 7. Establish a gas-distributing belt and an external cover. |
