9. GEAR
During the dismantling-assembly handle every component carefully, avoiding shocks and
damages; use suitable equipment.
9.1. Vertical shaft disassembly (Tab. 06)
ATTENTION
When disassembling is suggested to put in a suitable area the dismantled components to make
easier finding them out and to verify the completeness of the assembly at the end of it.
To dismantle vertical shaft, first of all move the helical gear wheel (parts from 07.220.0 to
07.260.0) to the right side sliding it along the horizontal shaft (Tab. 07). Then proceed as
follows:
1)
Remove screws (06.300.0) and cage cover (06.280.0) with its gasket (06.270.0).
2)
Lift labyrinth (06.250.0) with its OR gasket (06.260.0).
3)
Remove elastic support assembly (06.190.0
06.240.0).
4)
Remove the spacer ring (06.180.0) and the frame ring (06.170.0).
5)
Extract vertical shaft (06.140.0) together with its ball bearings.
6)
Extract spheric support with all its parts (06.042.0 ÷ 06.065.0) by screwing a M10 screw
into its threaded hole.
7)
Remove the three screws (06.040.0) and then screw two of them on threaded holes of
bush (06.020.0).
9.2. Vertical shaft assembly (Tab. 06)
Before assembly vertical shaft accurately clean and check all parts, paying particular attention
to gaskets and ball bearings.
1)
Insert spheric support with all its parts (06.042.0 ÷ 06.065.0) into bush (06.020.0).
2)
Fix bush (06.020.0) with its OR gasket (06.010.0) to frame and fix it with the screw
(06.040.0)
3)
Assemble all parts from (06.070.0) to (06.160.0) on vertical shaft (06.140.0). The two
thrust ball bearings (06.080.0) must be set as shown in the figure below:
