Dismantling
PERFORMANCE ORDER |
1. Merge oil from картера the steering mechanism. Fix картер on arm А.74076/R with support А.74076/1. |
2. Having turned away a nut of fastening the helmsman сошки 2 (fig. of the Detail of a reducer of the steering mechanism see) and having removed a spring washer, stripper А.47043 remove сошку (fig. Removal сошки see). |
3. Having turned away fastening bolts, uncover 12 (fig. of the Detail of a reducer of the steering mechanism see) картера the steering mechanism together with the adjusting screw 8, an adjusting plate 9, a lock washer 10 and a counternut. |
4. Take out from картера 1 shaft 7 сошки in gathering with a roller. |
5. Having turned away fastening bolts, uncover 3 persistent bearings of a shaft of a worm together with adjusting linings 4. |
6. Shaft 11 worms push out from картера an external ring 5 bearings and take out a shaft together with separators of 6 bearings. |
7. Remove an epiploon 15 shaft of a worm and an epiploon 16 shaft сошки. |
|
8. The adaptation 3 (оправкой 67.7853.9541) выпрессуйте an external ring of the top bearing 2 (1 – картер the steering mechanism). |
|
Assemblage
PERFORMANCE ORDER |
1. Assemblage of the steering mechanism spend on arm А.74076/R in sequence, return dismantling. |
2. An external ring of the top bearing of a worm запрессовывайте оправкой 67.7853.9541, having rearranged a nozzle on the handle оправки an underside. |
3. After installation of a worm in картер the steering mechanism and fastening of the bottom cover, check up by means of a dynamometer 02.7812.9501 and heads А.95697/5 (fig. the Control of the moment of a friction of a worm a dynamometer see) the moment of a friction of a shaft of a worm; it should be in limits 19,6–49 Н·см (2–5 кгс·см). |
|
4. If the moment appears less specified, reduce a thickness of adjusting linings 2; if more – increase (1 – a bearing cover; 3 – a worm). |
5. After shaft installation сошки check up absence of a backlash in gearing of a roller with a worm in positions of a shaft of the worm turned to the right and to the left on 30 ° from neutral position сошки. |
6. A possible backlash in gearing eliminate the adjusting screw 2 (fig. the Cut картера the steering mechanism see) and tighten a counternut 3. |
7. After backlash adjustment in gearing of a roller and a worm check up a dynamometer the moment of a friction of a shaft of a worm which should be equal 88,2–117,8 Н·см (9–12 кгс·см) at turn of a shaft of a worm on 30 ° both to the left, and to the right from average position and should decrease smoothly to 68,6 Н·см (7 кгс·см) at turn from a corner 30 ° against the stop. |
8. Upon termination of assemblage check up angles of rotation сошки from neutral position which should make 32°10’±1 ° both to the left, and to the right against the stop сошки in heads of bolts, fill in in картер the steering mechanism of 0,215 l трансмиссионного oils ТАД-17и. |
