4.6 - CHANGING THE PUMPING GROUP
In order to replace the pump group proceed as follows:
Before performing this operation stop the
pump and than shut-down the engine.
The operator must be carefully trained before
doing this operation.
Before the opening of a coupling, check that there is no
pressure inside the hoses and that no one stands too
close to the hoses.
This operation, that could be dangerous, must be carefully
carried on by qualifi ed personnel.
• Raise the vibrating slieve, the protection grill in the hopper
and lock it by using the hook.
• Remove the fi xing screw between the worm and the
agitator shaft.
• Fully loosen the clamp regulation bolts (33) and then
enlarge the clamp using the two relative screws (41) .
• Remove the material outlet collector by loosening the
nuts (42) on the two rods.
Take the stator / rotor
assembly and put it in
a vice, block the stator and
with a 12 mm rod of suitable
length (80 cm) threaded into
the worm fi xing eye to the
cardan coupling of the agitator
shaft unscrew the worm until
removing it.
Check if the be worm is
still usable (there must not
more than 3 mm wear) and
if necessary change the rotor
together with the stator.
You may check this data by laying the rotor on an horizontal
plane and by checking that the edges of the screw
(43) are
not further than:
- 78 mm for the 60.12 worms.
For mounting the worm smear it well with Vaseline or tire
grease (do not absolutely use mineral oil or grease).
The stator would be damaged beyond repair and than with
the same procedure that use to disassemble the lot refi t
the worm inside the stator.
The stator must be mounted with the embrasure side
towards the hopper.
