Disassemble

1

Detach cluster gear (9) using a three-arm puller from the intermediate shaft (15).

 Place matching thrust piece onto intermediate shaft (15).
Otherwise the thread of the intermediate shaft (15) may be damaged.

 A screw M10 with matching deep socket can be used as the thrust piece.

2

Remove tapered roller bearing (8) from cluster gear (9).

3

Remove the spacer ring (12) and shim (13) from intermediate shaft (15).

4

Detach tapered roller bearing (14) from intermediate shaft (15) using suitable thrust piece.

 The following special tools are required for this:  Hand pump,  hydraulic cylinder,  hydraulic hose (assembly),  adapter,  adapter,  adapter,  gripper

5

Remove tapered roller bearing outer race (14.1) from cluster gear (9) using the  internal extractor and the  counter stay.

6

Remove spacer ring (11) and retaining ring (10) from the cluster gear (9).

7

Remove tapered roller bearing outer race (8.1) from the cluster gear (9) using the  internal extractor and the  counter stay.

Assembly

8

Install circlip (10) in cluster gear (9).

9

Insert spacer ring (11).

10

Using a suitable drift, drive the tapered roller bearing outer race (14.1) in as far as the stop in the cluster gear (9).

11

Rotate cluster gear (9) and drive in tapered roller bearing outer race (8.1) using suitable drift up to end stop in cluster gear (9).

12

Insert tapered roller bearings (8, 14) into tapered roller bearing outer races (8.1, 14.1) and readjust.

 Readjust tapered roller bearings (8, 14) in cluster gear (9) using a press with max. 1 t.

13

Use vernier caliper to measure from cluster gear (9) to tapered roller bearing (14) and set vernier caliper to 0.

14

Use the vernier caliper to measure from the cluster gear (9) to the contact surface of the tapered roller bearing (8) = dimension (A).

15

Remove tapered roller bearings (8, 14) from the cluster gear (9).

16

Put the tapered roller bearings (8, 14), spacer ring (12) and shim (13) on top of each other.

17

Use vernier caliper to measure height of both tapered roller bearings (8, 14) with spacer ring (12) and shim (13) = dimension (B).

18

Determine axial play. Dimension (B) must be greater than dimension (A)  by the end play specified in the table.

 Compensate for any deviations by installing an appropriate shim (13). The end play should be in the region of the lowest tolerance limit.

19

Heat up tapered roller bearing (14) to approx. 80 °C.

20

Mount heated tapered roller bearing (14) on intermediate shaft (15) and reposition up to the stop using a suitable drift.

21

Let tapered roller bearing (14) cool down and then lubricate.

22

Fit determined shim (13), spacer ring (12) and cluster gear (9) onto intermediate shaft (15).

 Observe installation position of cluster gear (9).

23

Heat up tapered roller bearing (8) to approx. 80 °C.

24

Mount heated tapered roller bearing (8) on intermediate shaft (15) and reposition up to the stop using a suitable drift.

25

Let tapered roller bearing (8) cool down and then lubricate.

26

Check cluster gear (9) for ease of movement.

If the cluster gear (9) moves sluggishly.



Disassemble cluster gear (9) again and then assemble again.
