4.3.1Assembly of bearing bracket

1.Place pump shaft (0702) in vertical position on the workbench.

2.Place bearing cover (1430) over pump shaft (0702). The countersunk-holes should point in the direction of the flange.

3.Assemble ball bearing (1440) on the pump shaft. Use a pipe and a plastic hammer and drive the bearing via the inner bearing ring carefully over the pump shaft (0702) until the inner bearing ring makes contact with the shaft shoulder.

4.Place support ring (1460) over the pump shaft (0702) and secure the ball bearing (1440) with circlip

(1450) on the shaft. The circlip (1450) should be fitted under axial pre-load into the groove in the pump shaft (0702).

5.	Mount the outer magnetic rotor (8320) on the flange	8610
	of pump shaft (0702). Make sure that the locking pins
	(8600) are coinciding with the holes in the flange.	8600
6.	Screw cap head screws (8610) into the magnetic
	rotor (8320). Tighten these cap head screws (8610)	8320

with Loctite 243 crosswise with the specified torque to fix the magnetic rotor (8320) on the pump shaft (0702). (See chapter 3.21.3.1)
