15.17. A steering reducer (and/m without the hydraulic booster) - dismantling
1. Unscrew a stopper from the removed reducer and merge oil
2. Release a lock-nut of the adjusting screw of a shaft of a reducer and turn out bolts of a cover of a reducer (photo).
3. Turn out the adjusting screw, rotating clockwise and uncover.
4. Remove a shaft of a soshka and get the adjusting screw.
5. By means of a special key unscrew an adjusting nut (photo).
6. Get a leading shaft of a reducer together with an adjusting nut (photo).
Do not allow shift of balls to end faces of worm cutting. Otherwise the worm part of a shaft will be damaged, in case of wear or damage and a worm it is necessary to replace a ball nut.
7. Needle bearings of a shaft of a soshka to remove it is not allowed in case of wear of bearings replace all reducer.
8. Turn out an adjusting nut and bring down from a nut an epiploon.
9. Hook and get an epiploon from the reducer case.
10. Wash out all details.
11. Examine teeths on a soshka shaft, check existence on them of cracks or agnails.
12. Check a condition шлицов a soshka shaft.
13. Check a cutting condition on the leader to a shaft, existence of cracks, agnails and other damages. Check freedom of rotation of a ball nut on a worm. Believe freedom of moving of balls, gradually overturning a shaft in vertical situation, balls should roll down under the influence of a body weight. Otherwise replace a leading shaft.
16.6 Extraction of a leading shaft of a reducer together with an adjusting nut
16.18 Creation of a preliminary tightness in bearings of a leading shaft of a steering reducer
At check do not allow a ball skatyvaniye in the end of tooth of worm cutting.
14. Check freedom of rotation of bearings of a reducer. In case of jamming replace the bearing assembled with an external holder.
15. Before assembly grease all details. Establish new epiploons so that the party with letters was turned outside. In epiploons put greasing.
16. Establish a new epiploon on an adjusting nut.
17. Establish a leading shaft assembled a nut in a reducer. Screw a nut on a carving in a reducer.
18. Create in bearings of a leading shaft of a reducer a preliminary tightness (photo). For this purpose gradually wrap an adjusting nut until then while the moment of resistance of a provorachivaniye of a shaft does not become equal specified in Specifications.
The moment is measured by a dinamometrichesky key with a scale in some N of m after a provorachivaniye of a leading shaft in both directions on some turns. To improve gearing шлицов with a key insert into a key head a slice of a plastic card.
16.20 Check of an axial gap of a shaft of a soshka 1. Adjusting washer 2. Люфт shaft of a soshka 3. Towards a reducer cover
16.27 Check the moment of resistance a provorachivaniya of a shaft of a soshka, gradually rotating the adjusting screw 1. Screw-driver
19. Grease a ring lock-nut with fixing structure and draw in it an adjusting nut, without allowing a provorachivaniye of an adjusting nut. Again check a preliminary tightness in bearings.
20. Establish in T - figurative cut of a shaft of a soshka the adjusting screw and check an axial gap of the screw in cut (photo). Compensate this gap to norm, having picked up an adjusting washer on thickness (see. Specifications).
16.22 Before cover installation on a shaft wrap the screw, rotating counter-clockwise
21. Establish in a shaft of the case of a steering reducer a new epiploon.
22. Rotating the adjusting screw counter-clockwise, establish on a shaft a case cover, screw a lock-nut (photo).
23. Establish on a cover laying, having greased from both parties with hermetic.
24. Turn a leading shaft by hand and establish a ball nut in average situation. Establish a soshka shaft with the screw. Be convinced that the central tooth on a shaft of a soshka entered into gearing with the central flute of a ball nut. At performance of this procedure do not damage an epiploon edge.
25. Tighten cover bolts with the set moment.
26. Fill in oil in a reducer and wrap a stopper.
27. Create a preliminary tightness in bearings of a shaft of a soshka, rotating the adjusting screw (photo). Resistance to a provorachivaniye of a shaft of a soshka should correspond specified in Specifications. The moment is checked at the provision of a shaft of a soshka in the provision of driving on a straight line.
28. Tighten a lock-nut and again check a tightness.
