1

Remove tapered roller bearing outer race (8.1) from cover (6) and remove compensating washer set (8.2) from cover (6).

2

Measure thickness of removed compensating washer set (8.2) and note down as dimension A.

3

Calculate thickness of compensating washer set required for test (8.2) and note down as dimension B.

 Dimension B = Dimension A - 0.06 ... 0.08 mm.

4

Place compensating washer set (8.2) for test with dimension B into cover (6).

 The compensating washer set (8.2) with dimension B creates a bearing play, which can then be measured during the test.

5

Install tapered roller bearing outer race (8.2) again.

6

Clean sealing surfaces on cover (6) and through drive (7) and mount cover (6)  .

7

Use suitable tool (22) to spin drive shaft (9) several times.

8

Mount drive flange (3) without radial shaft sealing ring onto drive shaft (9), while doing so tighten the collar nut (2) to 200 Nm and do not yet lock.

9

Position dial indicator (24) with dial indicator holder (23) on through drive so that the tip of the dial indicator makes slightly pressurized contact with the drive shaft (9).

10

Set scale of dial indicator (24) to "0".

11

Position lever (25) between drive flange (3) and cover, and push drive flange (3) upwards and hold there.

12

While the drive flange (3) is pushed up, read off the axial play on the dial indicator (24) and note down as dimension C.

13

Detach dial indicator (24), collar nut (2) and drive flange (3).

14

Detach cover (6) again.

15

Remove tapered roller bearing outer ring (8.1) and compensating washer set (8.2) with dimension B from cover (6).

16

Calculate thickness of compensating washer set (8.2) required to achieve the required bearing pre-load and note down as dimension D.

Dimension D = Dimension B + dimension C + 0.02 mm

17

Insert compensating washer set (8.2) with dimension D into bearing cap (6).

18

Install tapered roller bearing outer ring (8.1) up to contact surface on compensating washer set (8.2) in cover (6).
