- differential boxes;
- differential bearings;
- clutch housing;
- gearbox housing.
1. Press the differential bearing outer race out of the transmission housing and remove the adjusting rings. Use puller ST33290001.
2. Press the bearing outer race without adjusting rings using ST30611000 and ST30621000 mandrels.
3. Install the differential into the clutch housing.
4. Connect the clutch housing to the gearbox housing. Tighten the mounting bolts to the torque specified in Section "Clutch and gearbox housings".
5. Install the dial indicator leg onto the end of the differential case.
6. Insert the mandrel into the axle gear until it stops.
7. By moving the mandrel up and down, determine the difference in the indicator readings.
8. Select the adjusting ring. Ring thickness - indicator deviation + required bearing tension.
The tension value and available thicknesses of the adjusting rings are given in the section "Data for adjustments and control".
9. Install the selected adjustment ring (one or more) and the outer ring of the differential bearing.
10. Check the torque of resistance to turning the differential. To do this, install the differential in the clutch housing, connect the clutch and gearbox housings, tightening the bolts to the required torque, and measure the torque with a torque wrench. The torque of resistance for new bearings is given in the section "Data for adjustments and control".
When reinstalling old bearings, the torque may be slightly less.
The change in the moment of resistance per one revolution of the differential should not exceed 1 Nm and should not be periodic in nature.
