Adjusting the rotary bearing units

1. Remove the hinge housing assembly to the drive shaft (see. Section Removal and installation of the drive shafts of the front axle).
2. Fill in the axle sleeve corresponding guide ring of a special remnabora - ring must without any play cling to the cage rotor bearing.
3. If necessary, align the punch rotary arm (1).
4. Install the top bolt wheel axis of rotation (2) with 2-mm spacer ring (3) and without shim (4).

The lower bolt last five millimeters in the tightness of the hinge assembly is seated in the housing (5), so before measuring shims between it and the inner race of the bearing is necessary to install spacer ring thickness of 6 mm. Another ring of 4 mm to be planted between the swivel arm and swivel casing.

5. Put the bolt into the lever enough to fully select taking place backlash bearing swivel head.
6. To shrink the bearing housing hinge rotate in different directions.
7. With the probe blade, measure the gap "A" between the casing (5) and bolt (2), then use the remote rings (6) define a gap "B" between the casing (5) and the pivot arm (1), - record the results of measurements .
8. Calculate thickness of shims as follows:

Upper swivel
The gap "A" = 1.30 mm
Thumbwheel = 2.00 mm
Bearing preload = 0.15 mm
The estimated thickness of shim = 2.00 - 1.30 + 0.15 = 0.85 (mm)

Lower swivel
Gap "B" = 1.10 mm
The difference thickness spacers = 6 - 4 = 2.00 (mm) (see. Note above)
Bearing preload = 0.15 mm
The estimated thickness of shim = 2.00 - 1.10 = 1.05 ?� 0.15 mm

9. Remove the guide ring and replace the hinge assembly in the drive shaft housing (see. Section Removal and installation of the drive shafts of the front axle).
10. The further installation is made in the reverse order of dismantle of components.
