8.4.3. Check of a condition of driveshaftsAt emergence of vibrations at high speeds of the movement it is necessary to check the size of a beating of driveshafts first of all.
|
|
- The car also establish to Poddomkratta it on props (see the illustration Scheme of an Institution of Props for fixing of the car in the lifted situation).
- Attentively examine driveshafts on existence of deformations and other mechanical damages.
|
- Manually turning a connecting flange of the corresponding main transfer, measure the size of a radial beating of the driveshaft by means of the dial measuring instrument of plunger type.
|
|
- If the result of measurement goes beyond repartitions of admissible range (see. The transmission line, Specifications), disconnect a shaft from a flange of the main transfer, turn it on 180 ° and again connect. Repeat measurement — at negative results of measurement replace a shaft.
|
|
- If noise in the central bearing took place, make its replacement.

|
Check on a workbench
|
|
- Remove the driveshaft, lay it in V-shaped blocks and measure the size of a radial beating. If the result of measurement exceeds limit value, admissible on Specifications (see. Transmission line), replace a shaft.
|
|
- Estimate side play size in the cardan hinge of a shaft — if the side play exceeds admissible value (see. The transmission line, Specifications), also make replacement of a shaft.
