Balancer shafts (on engines of 2,7 l) are installed on both parties of the block of cylinders and have the drive from a separate chain (see rice. Details of a forward part of the engine).
Removal
| PERFORMANCE ORDER |
| 1. Remove a natyazhitel of a chain N1, a guide, an asterisk of N1 and a chain of a cam-shaft. |
|
|
2. Record a plunger of a natyazhitel of a chain of the balancer shaft by means of the probe (1). |
|
3. Turn off a bolt and remove an uspokoitel of N2. |
|
4. Turn off bolts (are specified by shooters) and remove an uspokoitel of N3. |
|
5. Turn off a nut (it is specified by an arrow) and remove a natyazhitel of a chain. |
|
6. Turn off a bolt and remove the leading gear wheel of the top shaft and a chain.
|

7. Turn off bolts (are specified by shooters) and remove an uspokoitel of N4. |
|
Check
| PERFORMANCE ORDER |
| Chain and gear wheels |
| 1. The chain and gear wheels change in a set. The gear wheel is pressed from a shaft. Clear details. |
| 2. Check a condition of details. At detection of wear tracks replace. |
| 3. The chain should be changed after a run or at noticeable damages, and also in the presence of a side play of links. |
| Balancer shaft |
|
4. Check an axial side play of a shaft, having displaced it back and having put forward. |
|
5. Get both shaft. |
| 6. Carefully check a condition of shaft (if necessary address to car service). |

Installation
Prevention
Before installation of balancer shafts it is necessary to install the crankshaft, pistons with rods and to expose the piston of the 1st cylinder in compression step VMT so that counterbalances of balancer shafts were below.
| PERFORMANCE ORDER |
| 1. Establish shaft and tighten bolts of covers. |
| 2. Establish an uspokoitel. |
|
|
3. Establish a balanced chain, having combined tags (2) on an asterisk of the crankshaft (1) and on a gear wheel of the balancer shaft (3) with distinctive links of a chain. One more distinctive link arrange opposite to a big adjusting tag of the leading gear wheel of the balancer shaft. Insert the roller of the leading gear wheel into an opening in a persistent plate of the balancer shaft. Combine small tags of the leading gear wheel with tags on a gear wheel of the balancer shaft. |
| 4. Tighten a bolt of the leading gear wheel with the set moment. |
| 5. Establish an uspokoitel of N3, then an uspokoitel of N2, having tightened bolts. Get the probe from a plunger. |
