4.3.5Assembly of the bearing bracket

1.Place the pump vertically on the workbench with the separation can (8330) pointed upwards.

2.Screw the 4 guiding pins (tool) into the threaded holes of the cap head screws (1410).

3.Screw a lifting eye bolt into the shaft end of pump shaft (0702).

4.Use a crane to fit the bearing bracket (1400) over the guiding pins to the intermediate cover from the top (see picture).

5.Remove the guiding pins and fit cap head screws (1410). Tighten cap head screws (1410) crosswise to fix the bearing bracket (1400) to the intermediate cover (8450).

6.Mount bearing bracket support (1700) to the bearing bracket (1400).

3.Calculate the required thickness of the shim (8100) between pump cover (4000) and pump casing (0010).

S = A – B + C. Axial clearance C between rotor shaft (0701) and pump cover (4000) – see table.
