Please note: The steering column can be disassembled and assembled either while it is installed on the vehicle or while it is removed; the procedure remains similar. The procedure described here applies to the column installed on the machine.
1. Remove the steering wheel from the steering shaft while the unit is removed from the vehicle as described previously (Section 8).
2. Remove the column switches (Section 9, paragraph 2).
3. Disconnect the mounting bracket from the switches.
4. Remove the safety plugs and remove the column switch housing by turning it to the left and pulling it (photo).

5. The double row ball bearing can be removed from its housing by first separating the two gripping devices. Remove the bearing using a piece of pipe as a punch.
6. Install the new bearing by performing these operations in reverse order. Please note the pusher gasket A (Figure 8.18).

10. When assembling, first insert the shaft into the column tube and then engage the lower part of the shaft with the flexible coupling, making sure that the recess in the shaft matches the bolt hole in the clamp.
11. Attach a temporary plastic centering gasket to the base of the column tube.
12. Install the locking cylinder and ignition shutter.
13. Install the switch housing into the column tube using new safety plugs.
14. Install the direction indicator and wiper switches and install the mounting bracket.
