1. The complete drive unit is secured vertically to a table (or the like) (200) with a hole enabling the shaft (5) to point vertically
down and to be secured vertically (201) in the correct distance (438 ± 2 mm).
2. The gear motor screw cover (1A) is removed.
3. The screw (21) is unscrewed from the shaft (5).
4. The washer (22), which consists of two parts attached to each other with some silicone, is removed. It is important that the
parts are positioned as shown on Figure 4 when assembled.
5. The bushing that follows the gear motor seen on Figure 5 (together with position 21 and position 22) is removed and the
surfaces between the shaft (5) and the hollow shaft of the gear motor 1 is lubricated using some thin oil – that eases
the disassembling of the two parts.
6. The fasteners (18, 19 and 20) is unscrewed (during assembly they must be tightened sequentially to 51 Nm using some
Loctite).
7. The gear motor (1) is carefully lifted. It is important that the shaft (5) is not bumbed hard from side to side as the shaft surfaces
collide easily with the fragile mechanical seal parts (30).
