21.10. Central bearing of the driveshaft

Check

PERFORMANCE ORDER
1. At wear of the bearing there is a characteristic noise and vibration. Remove the driveshaft and check a bearing condition.
2. Check that the bearing rotates evenly both without jammings and in it is absent люфт. In the presence of defects replace the bearing. Check a condition of a rubber protective cover and, if necessary, replace it.

Replacement


Prevention

For replacement of the central bearing of the driveshaft use of a stripper and a hydraulic press, and also the corresponding opravka is necessary.


Elements of the central part of the driveshaft
1–forward part of the driveshaft;
2–back part of the driveshaft;
3–nut of the shlitsevy coupling;
4–rubber protective cover;
5–protective cover;
6–protective cover;
7–arm of the central bearing;
8–bearing

PERFORMANCE ORDER
1. Remove the driveshaft.
2. Put combination labels on forward and back parts of the driveshaft. On some models on kardanny to a shaft already there are combination labels. The label on a forward part of the driveshaft should settle down between two labels on the universal hinge of a back part of the driveshaft (see fig. An arrangement of labels of combination on both parts of a power shaft the file).
3. Disconnect a rubber protective cover from a nut of the shlitsevy coupling, then unscrew a nut and separate both half of the driveshaft (see fig. Elements of the central part of the driveshaft).
4. Remove from the driveshaft a rubber protective cover.
5. Using a stripper, remove the central bearing with an arm from the driveshaft, noting its arrangement. Remove forward and back covers of the central bearing.
6. Establish an arm with the bearing on a support and, using a tubular opravka of the corresponding diameter, squeeze out the bearing from an arm.
7. Check a condition of all details and, if necessary, replace. It is necessary to replace protective covers of the central bearing and a rubber protective cover from their condition.
8. Establish an arm of fastening of the bearing on a support and, using a tubular opravka which leans on an external ring of the bearing, press the new bearing into an arm.
9. Clear the driveshaft and establish a new back protective cover.
10. Establish the central bearing with an arm on the driveshaft, using the tubular opravka leaning on an internal ring of the bearing.
11. Establish on the driveshaft a forward protective cover and a new rubber protective cover, having established it in driveshaft flutes.
12. Apply a thin film greasings on the basis of a molybdenum disulfide on a shlitsa of the driveshaft and connect two parts of the driveshaft according to the labels put earlier.
13. Insert a rubber protective cover into a flute of a nut of the shlitsevy coupling and establish the driveshaft.
