Measurement of the load of the primary, secondary shaft and the shaft of the differential housing of the main transfer
Install the input shaft to the gears and the differential in the clutch housing.
| Fig. 3.67. Installing the primary shaft and the shaft of the differential
|
Install final drive housing and tighten fasteners primary shaft rated torque (Fig. 3.67). The inhaling moment: 37,3-52,0 Nm.

|
Install special tool and the dynamometer or a torque wrench (Fig. 3.68). Make sure that the pre-load - within limits. If not, repeat the operation, starting with the adjustment of a tightness in the bearings. Preload: 1.4-1.9 Nm. Indications dynamometer: 14-19 N. Remove special adaptation.

Place the gearbox in unit with the main gear, as shown in Figure 3.69, set a special device on the input shaft. Make sure that the pre-load - within limits. If not, repeat the operation, starting with the adjustment of a tightness in the bearings. Preload: 0,12-0,39 Nm. Indications dynamometer: 1,2-3,9 N. Remove special adaptation, housing the main transmission input shaft and differential. Install the secondary shaft and main gear housing, tighten the fasteners nominal torque. The inhaling moment: 37,3-52,0 Nm.
| Fig. 3.70. Measurement of the load of the secondary shaft with a torque wrench
|
Install special tool and the dynamometer or a torque wrench (Fig. 3.70). Make sure that the pre-load - within limits. If not, repeat the procedure starting with the adjustment of a tightness in the bearings. Preload: 0.2-0.3 Nm. Indications dynamometer 2-3 N. Remove the special tool and the main transmission housing.
