1

Determine required thickness of thrust plate (34).
 

 To do so, place the synchronizer body (25), spacer sleeve (31), thrust plate (34), spacer sleeve (35) and synchronizer body (39) on the  feeler gauge (42) and check the protrusion (A).
Use thrust plate (34) with the appropriate thickness if the protrusion (A) does not match the specified value. Thrust plates are available in thicknesses of 5.70 to 6.15 mm in steps of 0.05 mm.

2

Press on spacer ring (19).

 Commercially available tools:
Workshop press.

3

Install 2nd gear needle roller bearing (20).

4

Fit friction ring (22) and cone ring (23) on 2nd gear idler gear (21).

 The cams of the friction ring (22) must point up (toward the output side). The cams of the cone ring (23) must engage in the notches of the 2nd gear idler gear (21).

5

 The teeth on the synchronizer ring (24) must point toward the 2nd gear idler gear (21). The cams of the friction ring (22) must engage in the notches of the synchronizer ring (24).

6

Put on synchronizer body (25).

 The inscription on the synchronizer body (25) must point up (toward the output side). The cams of the synchronizer ring (24) must engage in the notches of the synchronizer body (25).

7

Press on 2nd gear idler gear (21) together with synchronizer body (25) using  sleeve.

 When pressing on, squeeze the synchronizer body (25) and the 2nd gear idler gear (21) together so that the cams of the synchronizer ring (24), cone ring (23) and friction ring (22) do not slip out of their respective notches.
Commercially available tools:
Workshop press.

8

Press on spacer sleeve (31) using  drift.

 Commercially available tools:
Workshop press.

9

Install 1st gear needle roller bearing (32).

10

Install sliding sleeve (27) and thrust pieces (26).

 The orientation groove (arrow A) on the sliding sleeve (27) must point down (toward the drive side). Push on the sliding sleeve (27) so that the balls of the thrust pieces (26) then engage in the center groove of the sliding sleeve teeth (arrow B).

11

Mount synchronizer ring (28).

 The teeth of the synchronizer ring (28) must point up (toward the output side). The cams of the synchronizer ring (28) must engage in the notches of the synchronizer body (25).

12

Attach cone ring (30) and friction ring (29).

 The cams of the cone ring (29) must point up (toward the output side). The cams of the friction ring (30) must engage in the notches of the synchronizer ring (28).

13

Install 1st gear wheel (33).

14

Position thrust plate (34) with determined thickness and press on spacer sleeve (35) using  drift.

 Commercially available tools:
Workshop press.

15

Install reverse gear needle roller bearing (36) and reverse gear idler gear (37).

16

Install synchronizer ring (38).

 The teeth of the synchronizer ring (38) must point down (toward the drive side).

17

Press on synchronizer body (39) using  drift.

 The grooves of the synchronizer ring (38) must engage in the notches on the synchronizer body (39).
Commercially available tools:

18

Install sliding sleeve (41) and thrust pieces (40).

 The orientation groove (arrow C) on the sliding sleeve (41) must point down (toward the drive side). Push on the sliding sleeve (41) so that the balls of the thrust pieces (40) then engage in the center groove of the sliding sleeve teeth (arrow B).

19

Install 3rd gear needle roller bearing (15).

20

Place clutch body (13) on 3rd gear idler gear (14).

 The shoulder on the 3rd gear idler gear (14) must point up (toward the drive side). The teeth on the clutch body (13) must point down (toward output side).

21

Mount friction ring (12) and cone ring (11).

 The cams of the friction ring (12) must point up (toward drive side). The cams of the cone ring (11) must engage in the notches of the clutch body (13).

22

Mount synchronizer ring (10).

 The cams of the friction ring (12) must engage in the notches of the synchronizer ring (10).

23

Mount synchronizer body (9).

 The cams of the synchronizer ring (10) must engage in the notches of the synchronizer body (9).

24

Press on synchronizer body (9) along with 3rd gear idler gear (14) using  drift.

 When pressing on, squeeze the synchronizer body (9) and the 3rd gear idler gear (14) together so that the cams of the synchronizer ring (10), cone ring (11) and friction ring (12) do not slip out of their respective notches.
