| 1. Carefully examine, whether there is no on working surfaces of a roller and a worm of wear tracks, a jamming, dents or рисок. The worn out and damaged details replace. |
| 2. Check up backlash size between plugs and shaft сошки which should not exceed 0,10 mm. If a backlash more specified, replace plugs, using оправкой А.74105. |
| 3. On an internal surface of plugs of a shaft сошки there are spiral flutes which leave only on one party of the plug. At запрессовке plugs have so that their end faces having an exit of flutes, were in an aperture картера, and exits of flutes have been located against each other. End faces of plugs should roll in an aperture картера on 1,5 mm. |
| 4. New plugs before запрессовкой grease трансмиссионным with oil. |
| 5. After запрессовки in картер definitively process plugs development А.90336 till the size of 28,698-28,720 mm. The assembly backlash between shaft сошки and plugs should be within 0,008–0,051 mm. |
| 6. Check up ease of rotation of a roller of a shaft сошки. |
| 7. Ball bearings of a worm and a roller should rotate freely, without jamming and on a surface of rings and balls there should not be a deterioration and damages. |
| 8. Check up palpation of a basic neck of a shaft of the steering mechanism concerning average diameter шлицевого apertures of a tip of a shaft. |
| 9. For check the bottom end of a shaft put on on special оправку which is established on призьму. At проворачивании оправки on a prism palpation of a basic neck of a shaft should not exceed 3 mm. |
| 10. Check up an axial backlash between a head of the adjusting screw 8 (fig. of the Detail of a reducer of the steering mechanism see) and a shaft groove сошки 7. The backlash should not exceed 0,05 mm. If it more, replace an adjusting plate 9 with a plate большей thickness. |
The prevention  In spare parts adjusting plates of eleven sizes, thickness from 1,95 mm to 2,20 mm are delivered; the increase in each size makes 0,025 mm.
