| 1. Protective covers of power shafts are very important elements since they protect hinges of equal angular speeds (SHRUS) from hit on them a dirt, water and other extraneous subjects causing damages. External pollution of protective covers by oil and greasings can lead to premature failure of a material of covers, therefore it is recommended to wash periodically covers with water with soap. | | 2. Examine covers on presence of ruptures and cracks, and also the weakened collars. In case of detection of signs of cracks or leak of greasing the cover should be replaced. |
| 3. At the same time check up the general condition of hinges of equal angular speeds, holding a shaft and simultaneously trying to turn a wheel. Repeat attempt, holding the internal hinge of equal angular speeds and turning a shaft. Any appreciable люфт specifies in deterioration of the hinge, deterioration in grooves of a shaft or отворачивание a lock nut of a shaft. | |
