8.6.2. Assembly of the agitator 

•

  Put the bearing stop ring (31) and the lip seal (88) in the base plate (42). 

•

  Next proceed to disassembly of bearings according to the case. 

 

- Agitator with bearing support with one ball bearing: 

 

 

Fit the ball bearing (70) and the elastic ring (66) on the half-shaft (26). 

 

After  the  half  shaft/ball  bearing  unit  has  been  assembled,  put  it  in  the  bearings  support  by  the  base 
plate side until it is positioned. Fit the unit of base plate (42), bearing stop ring (31) and lip seal (88) on 
the half shaft. Fit all through the countersunk screws (50). 

 

Mount  the  motor  (93)  on  the  bearing  support  (06)  and  fix  it  with  the  hexagonal  screws  (52)  and  flat 
washers (53). 

 

Joint the agitator shaft (05) with the half shaft using the allen studs (55A). 

 

Place the marine propeller (02) in the agitator shaft and tighten the allen studs (55). 

 

Fit the agitator over the tank. 

 

- Agitator with bearing support with two ball bearing: 

 

 

Fit  the  lower  elastic  ring  (66)  of  bottom  ball  bearing  (70)  with  suitable  pliers.  Enter  the  bottom  ball 
bearing (70) through the top part of the agitator shaft (05), and fix it through the elastic ring (66). Then 
repeat the same way for the upper ball bearing (70A). 

 

After  the  shaft  and  ball  bearings  unit  has  been  assembled,  put  it  in  the  bearings  support  by  the  base 
plate side until it is positioned. Fit the unit of base plate (42), bearing stop ring (31) and lip seal (88) on 
the agitator shaft (05). Fit all through the countersunk screws (50). 

 

Mount  the  motor  (93)  on  the  bearing  support  (06)  and  fix  it  with  the  hexagonal  screws  (52)  and  flat 
washers (53). 

 

Place  the  sawtooth  propeller  (02).  Firstly,  put  the  propeller  bucket (02A)  with  dragging  pivots  (02C)  at 
the  end  of  the  shaft.  Locate  the  holes  of  the  sawtooth  propeller  (02)  with  dragging  pivots  (02C).  The 
direction of rotation must consider. Next, locate the holes of the washer (02B) with the dragging pivots 
(02C) and, finally, tightening the hexagonal screw (52A). 

 

Fit the agitator over the tank.
