|
Fig. 3.67. Installation of primary shaft and differential shaft
|
Establish a case of the main transfer and tighten fixture of primary shaft nominal effort of an inhaling (fig. 3.67). Inhaling moment: 37,3–52,0 N · m.
|

Fig. 3.68. Measurement of loading of a shaft of differential by means of a dinamometrichesky key
|
Establish the special adaptation and a dynamometer or a dinamometrichesky key (fig. 3.68). Be convinced that preliminary loading – within norm.
If it not so, repeat operations, since tightness adjustment in bearings.
Preliminary loading: 1,4–1,9 N · m.
Dynamometer indications: 14–19 N.
Remove the special adaptation.

Fig. 3.69. Measurement of loading of primary shaft by means of a dinamometrichesky key
|
Establish a transmission in the block with the main transfer, as is shown in drawing 3.69, establish the special adaptation on primary shaft. Be convinced that preliminary loading – within norm.
If it not so, repeat operations, since tightness adjustment in bearings.
Preliminary loading: 0,12–0,39 N · m.
Dynamometer indications: 1,2–3,9 N.
Remove the special adaptation, a case of the main transfer, primary shaft and differential.
Establish a secondary shaft and a case of the main transfer, tighten fixture nominal effort of an inhaling.
Inhaling moment: 37,3–52,0 N · m.

|
Fig. 3.70. Measurement of loading of a secondary shaft by means of a dinamometrichesky key
|
Establish the special adaptation and a dynamometer or a dinamometrichesky key (fig. 3.70). Be convinced that preliminary loading – within norm.
If it not so, repeat operations beginning, from tightness adjustment in bearings.
Preliminary loading: 0,2–0,3 N · m.
Dynamometer indications: 2–3 N.
Remove the special adaptation and a case of the main transfer.
