8.6.  DISASSEMBLY AND ASSEMBLY OF THE AGITATOR 

 

The  disassembly  and  assembly  of  the  agitators  should  only  be  carried  out  by  qualified  personnel 
using  only  appropriate  tools.  Ensure  that  staff  read  these  instructions  manual  attentively, 
particularly the instructions that relate to their work. 

 

Stop the motor from starting up when carrying out assembly and disassembly work on the agitator. 
Place the agitator switch in the “off” position. 
Lock out the electrical switchboard or place a warning sign. 

Remove the fuses and take them to the workplace. 

 

 

8.6.1. Disassembly of the agitator 

Once the motor is disconnected, disassembly work may begin: 

  Empty the tank. 

  Remove the propeller (02) that is screwed to the agitator shaft (05) knocking a blade lightly with a plastic 

hammer in counter-clockwise direction as seen from the front of the propeller. Take care to retain the O-
ring (80) in the agitator shaft (05). 

  Remove carefully the two parts of the mechanical seal (08), loosening the allen studs that hold them. 

  Remove shaft guards (47) together with its hexagonal screws (52B) and flats washers (53B). 

  Remove the hexagonal screws (52C) from the motor or gear motor and loosen the allen studs (55A) from 

the bearing support (70). 

  Move the motor or gear motor and the agitator shaft (05) backwards, taking  care not to hit or strain the 

agitator shaft.  

  Remove the allen studs (55) that fix the shaft to the motor and separate the motor or gear motor (93) of 

the agitator shaft (05). 

  Finally,  remove  the  hexagonal  screws  (52,  52A),  flat  washers  (53,  53A)  that  separate  the  flange  (23) 

from the lantern (04) and the latter from the bearing support (70). 

8.6.2. Assembly of the agitator 

  Assemble the agitator shaft (05) onto the motor or gear motor (93). Locate the threaded holes above the 

keyway. Introduce the  allen studs into these  holes and tighten until they  lock on the keyway. The  allen 
studs must not protrude from the external diameter of the shaft.

 

  Assemble  the  bearing  support  (70)  in  the  lantern  by  means  of  the  hexagonal  screws  (52A)  and  flat 

washers (53A), without tightening them.

 

  Introduce the agitator shaft and the motor through the bearing support (70) until the flange of the lantern, 

and firmly tighten the hexagonal screws (52C).

 

  Tighten the hexagonal screws (52A) of the bearing support (70).

 

  Next, place the flange (23) on the lantern centering (04) fixing through the hexagonal screws (52) and flat 

washers (53).

 

  Check  that  the  surfaces  of  the  agitator  shaft  (05)  and  the  flange  (23)  are  in  good  condition  (perfectly 

polished finish).

 

  When fitting the new seals, be sure to wet the O-rings with soapy water so that the fixed parts slide easily 

into their locations and the rotating parts onto the shaft.

 

  Place the stationary part of the mechanical seal (08) on its location on the flange (23).

 

  Place the rotating part of the mechanical seal (08) and fix it to the agitator shaft through its fixing studs as 

shown in the assembly instructions, figure 8.1.

 

  Locate the shaft guards (47) with the hexagonal screw (52B) and flat washers (53B) to the lantern (04).

 

  Place the O-ring (80) on the agitator shaft (05).

 

  Install the agitator in the flange of the tank.

 

  Finally, mount the propeller (02) firmly on the agitator shaft (05), checking that it will not become loose.
