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).

4.3.2.2Assembly of rotor shaft

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.

Remark: Do not use any force while mounting the shaft sleeve (8350-B) and no hammer to drive it in. These parts are very sensitive and should be handled with utmost care in order not to damage them during assembly. The parts should fit into each other smoothly and under light pressure by hand. If it is not possible to fit these parts by hand, disassemble the parts and check if the parts are not damaged or if there is any dirt between the fitting faces.
