Prevention
At installation of an asterisk of a camshaft and a new directing chain it is necessary to use new bolts.
TOP CHAIN AND ASTERISKS
Removal
| PERFORMANCE ORDER |
| 1. Remove a weight wire from the accumulator. Uncover heads. |
| 2. Establish the piston of the first cylinder in the top dead point in a step of compression and fix a cranked shaft. |
3. For improvement of access to a cover of an asterisk of the fuel pump execute the following actions:
– remove a casing of the air filter and a forward exhaust pipe;
– remove an auxiliary driving belt;
– unscrew a nut of fastening of a support of the power unit on the right side of the engine, raise the engine as far as possible not to deform hoses and tubes. |
| 4. Remove the top and bottom natyazhitel of a chain. |
| 5. Unscrew an auxiliary rack of a pulley of the mechanism of a tension, the bottom and sharnirny bolt of a basic plate and remove the tension mechanism from the engine. |
|
6. Unscrew bolts of fastening of a cover of an asterisk of the fuel pump |
|
7. Uncover asterisks of the fuel pump. |
| 8. Establish blocking pins in asterisks of the fuel pump and a camshaft. |
| 9. Unscrew bolts and remove top directing to a chain from the top part of a head of the block of cylinders. |
Prevention
Before unscrewing of the top bolts of them directing to a chain it is necessary to heat up to soften the structure interfering unscrewing of bolts.
|
|
10. Heat up the top bolts directing to a chain for simplification of their unscrewing. |
|
11. Unscrew bolts of fastening of the top directing chain. |
|
12. Remove top directing to a chain. |
|
13. Using a wrench, fix a camshaft from provorachivaniye and weaken a bolt of fastening of an asterisk of a camshaft. Check that the chain is correctly established on an asterisk of a camshaft and, using a soft wire, adhere a chain to an asterisk. If blocking pins are used, remove them before weakening of bolts of fastening of an asterisk and establish into place after weakening of a bolt. |
|
14. Take pins of blocking of the fuel pump and weaken the bolts, fixing asterisks of the fuel pump to a pump ledge. Unscrew bolts and remove an asterisk of the fuel pump. Remove a chain from an asterisk of the fuel pump then remove an asterisk from a camshaft and take it together with a chain from the top part of a head of the block of cylinders. |
|
BOTTOM CHAIN AND ASTERISKS
Removal
| PERFORMANCE ORDER |
| 1. Remove the top chain and asterisks. |
| 2. Uncover chains. |
| 3. Put combination labels on a chain and asterisks. |
|
4. Remove an asterisk of the fuel pump together with a chain. |
|
5. Remove an asterisk from a cranked shaft. |
|
6. Remove a segment shponka from a cranked shaft. |
|
Check
| PERFORMANCE ORDER |
| 1. Check a condition of teeths of asterisks on wear and damage. In the presence of defects of asterisks, it is necessary to replace asterisks and a chain. |
| 2. Check a condition directing to a chain and edges of the mechanism of a tension on existence of wear and damages. |
|
TOP CHAIN AND ASTERISKS
Installation
| PERFORMANCE ORDER |
| 1. If new details are established, transfer on them combination labels from earlier standing details. Check that the cranked shaft is fixed in the provision of the top dead point of the piston of the first cylinder. Establish an asterisk of the fuel pump together with a chain through the top part of a head of the block of cylinders. |
| 2. Establish an asterisk of the fuel pump and dress on it a chain. |
| 3. Check that earlier made labels are combined, and establish an asterisk of the fuel pump and a camshaft. Remove a wire adhering a chain to an asterisk of a camshaft. |
|
4. Combine an adjusting label of an asterisk of the fuel pump with an opening in a pump ledge (it is specified by an arrow) and tighten fastening bolts by hand. |
|
5. Establish a new bolt of fastening of an asterisk of a camshaft and tighten it by hand. |
| 6. Establish the bottom natyazhitel of a chain. |
|
7. Establish top directing to a chain and fix bolts, having tightened them the demanded moment (it is specified by an arrow). |
| 8. Establish pins of blocking of the pump, a camshaft and a cranked shaft. If necessary adjust a drive of the mechanism of a gazoraspredeleniye. |
| 9. Establish the top natyazhitel of a chain. |
| 10. Check that interfaced surfaces of a cover of an asterisk of the fuel pump and a chain cover, pure and dry. Establish a cover with use of thin laying or a thin layer of hermetic. Tighten bolts of fastening of a cover the demanded moment. |
| 11. Establish the mechanism of a tension of a driving belt. |
| 12. Convert the right support of the power unit to a head of the block of cylinders. |
| 13. Establish a cover of a head of the block of cylinders. |
| 14. Establish a forward exhaust pipe, a casing of the air filter and the sensor of a cranked shaft. |
|
BOTTOM CHAIN AND ASTERISKS
Installation
| PERFORMANCE ORDER |
| 1. At installation of new details transfer on them combination labels from earlier removed details. |
| 2. Establish a segment shponka in a groove of a cranked shaft and establish an asterisk of a cranked shaft, combining a groove on an asterisk with a segment shponka. |
| 3. Check that the asterisk of the fuel pump is correctly combined, and the cranked shaft of the engine is fixed in the provision of the top dead point of the piston of the first cylinder. |
| 4. Check combination of labels, establish a chain on an asterisk of the fuel pump and establish an asterisk into place. Check that all labels made before removal, are correctly combined. |
| 5. Establish a cover of a chain and establish the top chain of a drive of the mechanism of a gazoraspredeleniye. |
