6.6 Hydraulic motor group assembly
- Place the new bellows (14) onto the chromium plated
shaft (4).
- Fit the bellows flange (26).
- Fit the piston (16) onto the bellows (14).
- Completely tighten the screw (18) and washer (17) into
the chromium plated shaft (4).
The operation enables the bellows (14) to fit completely
onto the shaft (4).
NOTES:
1) The inside diameter of the bellows is smaller than the
diameter of the shaft, hence it is impossible to fit it
manually.
2) Make sure the bellows is aligned with the motor shaft.
- Unscrew the screw (18) again; apply a layer of loctite
(medium) and then tighten completely.
- Position the takeup hub (28) and the lip seal (31).
- Position the pumping hub (32) and tighten the screws
(34) symmetrically and progressively.
IMPORTANT:
When positioning the lip seal, the piston must be com-
pletely moved back (towards the pneumatic motor)
because the inside diameter of the seal is much smaller
than the diameter of the piston.
The piston will fit into the seal on completion of assem-
bly, when the pump will be enabled.
