6.  Peel the required number of layers off the bearing shim 

(8470) to adjust the thickness of the shim S to the required 
value.

7.  Un-tighten cap head screws (8480) and remove radial  

bearing holder (8350-C) from the intermediate cover 
(8450).

8.  Assemble radial bearing holder (8350-C) again in the same 

way with the shim placed between holder and intermediate 
cover (8450).

9.  Place front axial bearing holder (8350-A) into the pump 

insert (8430) until the axial bearing faces are making contact 
and check if the axial clearance C of the circulation pump is 
correct. Dimension X should be within the range of dimen-
sion C. (See point 5).

1.  Place the shaft rotor on the workbench in vertical  

position, put a thin layer of grease on all sliding faces of  
the bearings.

2.  Place the disk rotor (8420) into the chamber of the pump 

insert (8430).

3.  Check that the axial contact faces of the axial bearing holder 

(8350-A) and shaft sleeve (8350-B) are undamaged and 
free of any dirt.

4.  Place the disk rotor (8420), the front axial bearing holder 

(8350-A) and the bearing arrangement over the shaft rotor 
(0701). Make sure that the pin (8410) in the rear face of 
the rotor is fitting into the hole of the axial bearing holder 
(8350-A).

5.  Push shaft sleeve (8350-B) carefully from the rear side  

into the radial bearing holder (8350-C). Do not use any 
force or a hammer while fitting the rotor shaft (0701) into 
the bearings.
