Fig. 3.67. Installation of a main shaft and shaft of differential
|
Establish a case of the main transfer and tighten fixture of a main shaft the nominal force 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 dynamometer key
|
Install special adaptation and a dynamometer or a dynamometer key (fig. 3.68). Make sure that preliminary loading – within norm.
If it not so, repeat operations, since adjustment of a tightness in bearings.
Preliminary loading: 1,4–1,9 N · m.
Indications of a dynamometer: 14–19 N.
Remove special adaptation.

Fig. 3.69. Measurement of loading of a main shaft by means of a dynamometer key
|
Install the transmission in the block with the main transfer, as shown in the figure 3.69, install special adaptation on a main shaft. Make sure that preliminary loading – within norm.
If it not so, repeat operations, since adjustment of a tightness in bearings.
Preliminary loading: 0,12–0,39 N · m.
Indications of a dynamometer: 1,2–3,9 N.
Remove special adaptation, a case of the main transfer, a main shaft and differential.
Establish a secondary shaft and a case of the main transfer, tighten fixture the nominal force 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 dynamometer key
|
Install special adaptation and a dynamometer or a dynamometer key (fig. 3.70). Make sure that preliminary loading – within norm.
If it not so, repeat operations beginning, with adjustment of a tightness in bearings.
Preliminary loading: 0,2–0,3 N · m.
Indications of a dynamometer: 2–3 N.
Remove special adaptation and a case of the main transfer.
