Removal
| PERFORMANCE ORDER |
| 1. Remove the oil pallet and a maslozaborny branch pipe. |
| 2. Establish the N1 piston in VMT, having combined a sinkhronizatsionny label of a pulley with the index on a cover. |
| 3. Unscrew bolts and remove the block of an equilibration of the cranked shaft, located in the basis of the block of cylinders. Remove a dividing plate. |
|
Installation
| PERFORMANCE ORDER |
| 1. If you carried out any works with cranked shaft or establish the new block of an equilibration, you need to adjust a gap of a tooth gearing. |
|
|
2. If you establish the old block, turn shaft so that cuts on their ends were directed down and were on one line. |
| 3. Establish a dividing plate and establish the block. |
| 4. Tighten bolts. |
| 5. Establish a maslozaborny branch pipe and the oil pallet. |
|
Adjustment
The gap of gear wheels is regulated by thickness of the dividing plate established between the block of cylinders and the block of an equilibration.

If you establish the new block, use the thickest plate of N85.
| PERFORMANCE ORDER |
| 1. Establish the N1 piston in VMT and prepare the KM-949 tool. Establish the measuring lever on the right shaft. The lever should be in horizontal situation. Twist both wheels in shaft, and strong tighten. Arrange the measuring device so that its probe entered into a flute on the measuring lever. |
| 2. Turn the left shaft up to the end clockwise and establish the measuring device on a zero. Turn a shaft up to the end counter-clockwise and write down measuring instrument indications. |
| 3. Clean the measuring device, turn a cranked shaft on 45 ° (shaft will turn on 90 °). Weaken a castor of the right shaft and establish the measuring lever in horizontal situation. Carry out repeated measurement. |
| 4. Repeat the procedure described above two more times that at you four results of measurements turned out. |
| 5. All received results should be in limits of 0,02-0,06 mm. If the result at least one of measurements is beyond the specified interval, it is necessary to carry out adjustment. |
| 6. The size of the received measurements is directly proportional to thickness of an established plate. |
