 Oil needle bearings (13) and thrust collar of 1st gear gearwheel (14).

4

Push on synchronizer body (15).

 The long collar of the synchronizer body (15) must point towards the 1st gear gearwheel (14).

5

Install determined retaining ring (16).

6

Install sliding sleeve (17).

7

Push reverse gear gearwheel (19) with needle bearing (18) onto main shaft (12).

 Oil needle bearing (18) and thrust collar of reverse gear gearwheel (19).

8

Press tapered roller bearing with pulse wheel (20) and sun gear (21) onto main shaft (12).


When pressing on, the centering pin (26) of the  pulling device (25) must engage in the oil hole (arrow A) of the main shaft (12).
Otherwise the thread of the main shaft (12) could be damaged.

 Position the sun gear (21) so that the chamfer on the internal toothing points towards the tapered roller bearing with pulse wheel (20) and the flat side faces the retaining ring (22).
