4.3.2 Pre-assembly of the back-pull-out
4.3.2.1 Adjustment of the axial clearance of the
circulation pump
1. Place pump insert (8430) and radial bearing holder
(8350-C) in the intermediate cover (8450). Do not
use any shim (8470) at this stage.

Remark: There are two different inserts according to
the sense of rotation of the pump shaft (see sketch).

2. Fit cap head screws (8480) and tighten them cross-
wise to fix the radial bearing holder (8350-C) and
insert (8430) to the intermediate cover (8450).

3. Mount axial bearing (8350-A) into the insert (8430).
Do not use any force and be careful not to damage
the bearing faces while pushing part (8350-A) in until
the bearing faces are making contact.

4. Measure the distance between front face of the axial
bearing holder (8350-A)(front face gear tooth) and
the front face of the crescent of the pump insert
(8430).

5. Calculate the required thickness of the bearing
shim (8470): S = X – C.
