8.4.3. Check of a condition of driveshaftsAt emergence of vibrations at high speeds of movement it is necessary to check size of palpation of driveshafts first of all.
|
|
- To Poddomkratta the car also establish it on props (see an illustration the Scheme of an institution of props for car fixing 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 size of radial palpation of the driveshaft by means of a tsiferblatny measuring instrument of plunzherny type.
|
|
- If the result of measurement leaves for repartitions of an 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 size of radial palpation. If the result of measurement exceeds limiting admissible value according to Specifications (see. The transmission line), replace a shaft.
|
|
- Estimate size люфта in the kardanny hinge of a shaft — if люфт exceeds admissible value (see. The transmission line, Specifications), also make shaft replacement.
